Metal stamping is a manufacturing process that employs a specialized press, as well as tool and die set, to form sheet metal into a specified shape and size. Industry professionals employ metal stamping processes to produce a wide range of industrial parts and products. When looking for a metal stamping partner, there are several considerations to bear in mind. You’ll want to vet a company that offers the greatest value for your project.
The following piece provides an overview of some of the key factors to consider when choosing a metal stamping partner. In addition to metal stamping capabilities, qualities such as a broad selection of other fabrication and finishing services, extensive industry experience, and high quality standards are indicative of a high-value partner.
Partner vs. Supplier
When sourcing a metal stamping company, it is important to know the difference between a supplier and a partner. While a supplier has the metal stamping capabilities necessary to fulfill the project, a partner offers the required metal stamping services and more. The latter should be able to assist with all project needs, including design and engineering assistance, manufacturing, and/or finishing services. These offerings help shorten production timelines and reduce production costs.
Advanced Stamping Capabilities
While specialization is good, narrow specialization is not. For example, some projects may not overtly indicate which metal stamping process is appropriate. A metal stamping company that offers a wide range of in-house stamping capabilities—e.g., bending, blanking, coining, piercing, etc.—is better able to accommodate such projects. However, for projects that required advanced metalworking—i.e., deep draw stamping—it is essential to work with a specialist to ensure greater precision and accuracy in the finished parts.
Tooling Design and Development Services
Metal stamping companies that maintain an in-house tooling design and development team have greater control over part and process quality. As they have the ability to create custom tooling for every project, they are better able to ensure production proceeds as intended.
As indicated above, a metal stamping partner should ideally offer more than just metal stamping capabilities. These secondary operations—provided in-house or through a network of reliable vendors—allow clients to receive a full-service stamping solution. Some of the other fabrication and finishing processes a partner may offer include:
Forming and welding
Painting and electrocoating
Passivation and sterilization
Pre-plating and post-plating processes
Precious and non-precious metalwork
Specialty edge cleaning and deburring
Kitting & Custom Packaging
Regardless of whether you [the customer] are in the aerospace, automotive, construction, appliance, or other industry, any potential metal stamping partner should have experience producing parts and products for your industry. This quality ensures the partner is familiar with any requirements or restrictions specific to the industry (e.g., using FDA compliant materials for medical devices).
Both the type of equipment employed and the lead time for raw material orders estimated affect a company’s production capacity. A metal stamping partner should utilize metalworking equipment that allows them to complete projects efficiently without sacrificing precision or accuracy.
The International Organization for Standardization (ISO) develops and publishes standards aimed toward ensuring the quality, safety, and efficiency of products and services. The ISO 9000 family of standards focuses on quality management principles regarding a company’s products and processes. Companies certified to ISO 9001 comply with the ISO’s criteria for quality management systems, meaning they are knowledgeable about best practices regarding quality and sustainability, and are actively and adequately working to integrate them.

Precision metal stamping is a manufacturing process that utilizes a custom tool and die set installed in a stamping press to turn sheet metal into the desired components. It is used in a wide range of industries to create large quantities of parts and products with high precision, accuracy, and speed. While this process offers manufacturing advantages, it is not appropriate for every production project.
The following article discusses some of the considerations to keep in mind when determining whether precision metal stamping is right for your project. It provides an overview of the process, the benefits it offers, and the typical industries that use it.
An Overview of Precision Metal Stamping
Metal stamping—also sometimes referred to as pressing—relies on specialized tooling (i.e., a tool and die set) and equipment (i.e., a press) to form metal sheets and coils into the required shape and size. The pressure exerted on the workpiece by the press forces the material to conform to the shape formed by the tool and die. This process can occur in a single stage or across several stages, depending on the simplicity or complexity of the end product. Precision metal stamping operations largely rely on the use of automated equipment, which ensures the finished components are both precise and accurate.
In addition to higher precision and accuracy, some of the other advantages the precision metal stamping process demonstrates over other manufacturing processes include:
Greater product and process quality. Accuracy offered by the precision metal stamping process translates to a lower error rate during production. This means there is a smaller chance of producing faulty or flawed parts making it into the hands of customers.
Lower production costs. A generally automated process, precision metal stamping mitigates the need for manual labor. This quality also results in a lower error rate, which translates to less material utilization and waste during a production run.
As indicated above, the precision metal stamping process finds application in a wide range of industries. Some of the industries that regularly employ the process for the production of their parts and products include:
In the automotive industry, stamping is used to create a variety of structural and functional parts used in vehicle bodies and frames, electrical systems, steering systems, and more. Some examples of typical automobile parts made in metal stamping operations include:

An aluminum alloy is a chemical composition in which other elements are added to pure aluminum to enhance its properties—primarily to improve its strength. The elements often added to aluminum include:
They can sometimes make up at least 15% of the final alloy by weight.
Every aluminum alloy is assigned a four-digit number. The first digit identifies the general class, or series, that is characterized by its main alloying elements. The types of alloys include:
Commercially pure alloys
Temper designations for non-heat-treatable alloys are indicated by a suffix added to the alloy number.
Some key characteristics of aluminum alloys are:
High strength-to-weight ratio
Flexible and malleable
Shiny and smooth decorative finish that requires little maintenance
Thermal and electrical conductivity
Low temperature resistance
Aluminum alloys provide a variety of benefits, particularly for applications that need strength without heavy weight. The alloys are one of the lightest metals used in commercial projects, and they often appear in applications for the transportation industry because reductions in weight help with fuel savings. Furthermore, aluminum alloys’ light weight and natural corrosion resistance result in the parts lasting longer as well as allowing them to be made from significantly less raw material. Since aluminum is flexible and malleable, metal stamping can form aluminum and aluminum alloys into complex geometric shapes.
Aluminum alloy applications include, but are not limited to, the following:
1100: Commercially pure aluminum. It is ductile and soft, with good workability. It’s useful for applications that require intricate forming because it hardens slower than other alloys. Common applications include kitchenware, decorative trim, and giftware.
3003: The most frequently used of all aluminum alloys. It is commercially pure aluminum with manganese added, which increases its strength by about 20% over 1100. It has great corrosion-resistance and workability, allowing it to be welded, deep drawn or spun, or brazed. Common applications include cooking utensils, kitchen equipment, and chemical equipment.
5052: The highest strength alloy of the common non-heat-treatable grades. Its fatigue strength is better than other alloys, and it has excellent resistance to the marine atmosphere and saltwater corrosion. It has optimal workability and good finishing characteristics. Its common applications include aircraft components, home appliances, and heavy-duty cooking utensils.
When choosing an aluminum grade, there are a few factors to consider:
Its level of formability or workability
Its level of corrosion-resistance
Typical end-use applications

Steel is one of the most widely used alloys and is comprised of carbon (less than 2%) and manganese (1%). Other small amounts of silicon, phosphorus, sulphur, and oxygen are also present. Steel is an integral component to almost all forms of production and construction, ranging from surgical equipment to household items.
This type of metal is 100% recyclable, and steel products last for approximately 40 years. It is produced from either the Blast Furnace Basic Oxygen Route (BF-BOF) or from the Electric Arc Furnace (EAF) route. Both of these routes contribute to the production of crude steel. The Blast Furnace Basic Furnace Oxygen Route utilizes the following to manufacture crude steel:
The Electric Arc Furnace Method utilizes all of these and electricity for crude steel manufacturing.
Since the magnetic properties remain unchanged, this metal can be continuously recycled. Recycled steel can serve as input for BF-BOF and EAP methods, contributing to the production of many new steel products. They contain approximately 37% of recycled steel. Because of its lightweight structure, cost efficiency, corrosion resistance, and energy efficiency, steel is used in almost every type of building and construction process. Applications constructed with this material include:
Buildings and infrastructure
Types of Steel Alloys
There are more than 3,500 grades of steel that are integral to engineering and construction projects. All contain forms of sulphur, phosphorus, and manganese. Manganese is beneficial to steel’s sustainability; however, too much phosphorus and sulphur in the alloy can have detrimental effects on steel’s durable properties.
There are four categories of this material:
Carbon Steels are used in 90% of steel production and contain trace elements of alloy products. They are classified into three subcategories: low, medium, and high. Low carbon steels contain up to 0.3% carbon, medium steels contain 0.3-0.6% carbon, and high steels contain more than 0.6%. They can be formed into a variety of shapes, ranging from Flat Sheet to Structural Beam.
Alloy Steels are used for pipelines, transformers, auto parts, power generators, and electric motors. Heat applications soften the material for welding and cutting applications. They contain:
Stainless Steels are extremely resistant to corrosion, due to its high chromium content (10-20%). They are grouped into three subcategories, based on crystalline molecular structure:
Martensitic (cutting tools, dental, and surgical equipment)
Tool Steels are durable and heat resistant. The addition of tungsten, molybdenum, cobalt, and vanadium makes the raw material suitable for the production of dental and surgical equipment.

Copper is widely regarded as one of the oldest metals used by man. For centuries, copper has been forged and shaped into a variety of useful everyday items from tools and jewelry to, more recently, electrical equipment and household appliances.
Copper possesses a broad range of desirable mechanical and chemical properties, making it one of the most versatile and extensively used engineering materials. The properties of copper can be further enhanced by alloying it with other metals, creating solutions for applications that would otherwise be unsuitable for either material alone.
The construction industry is the single largest consumer of copper, with an annual consumption rate of 47%. The electrical industry is also known for its heavy reliance on copper, with an annual usage of 23%. Other sectors such as the transportation, consumer products, and machining industries account for the remainder of copper usage.
The usage of copper and its alloys continues to grow exponentially, with the total annual consumption across all industries currently exceeding 18 million tons per annum.
Copper alloys usually come in the form of brass, phosphor bronze, aluminum bronze, silicon bronze, cupronickel, and nickel silvers. Each of these alloys enhances the properties of copper and can be stamped for use in numerous applications across a broad spectrum of industries. Typical applications for copper alloys include, but are not limited to:
Electrical wiring and circuitry
Refrigeration tubing and coils
Power transmission lines
Arms and ammunition
Compared to other metals, copper possesses the highest level of electrical conductivity. second only to silver—the conductivity of copper is 97% that of silver. This attribute, coupled with other unique properties make copper ideal for electrical components such as connectors, coils, and terminals.
Copper is also widely praised for its excellent corrosion resistance, especially in freshwater and high-temperature environments. When exposed to air and moisture, copper forms a thin, durable, and tightly adherent oxide film known as patina. The patina layer acts as a barrier which blocks moisture from coming into contact with the underlying material, thus preventing further corrosion.
Finally, the copper property most pertinent to metal stamping is its formability. Copper is highly malleable and ductile, allowing it to be formed into a variety of shapes for almost any application. Copper alloys such as brasses, bronzes, and nickel silvers increase in strength during cold working in a process known as work hardening. This process readjusts the copper’s crystalline structure, making it resistant to further deformation. Deep drawing, coining, bending, and stretching are some of the forming methods used to create a wide range of components, such as bathroom fixtures and household appliances.
Other desirable properties of copper include excellent biofouling resistance, non-magnetic structure, superior thermal conductivity, and ease of joining (bolting, welding, riveting, brazing, soldering).
