When choosing the best material for metal stamping, it’s important to consider the complexity of the final product and the characteristics you need it to exhibit. Copper, steel, and aluminum alloys are all common material options for metal stamping. Here, we will describe each material and its benefits to help you determine which metal is right for your next metal stamping project.

Choosing the Best Metal for Stamping

The material you choose for your metal stamping project greatly affects the final outcome of the finished product. To ensure that you select the right metal based on your project’s requirements, it’s important to ask yourself the following questions:

  • How much does the material cost and will it fit into your project’s budget?
  • Will the material be easy to work and shape into the desired product?
  • How strong and durable does the material need to be?
  • What sort of environmental conditions will the material need to withstand?
  • What long-term benefits does the material need to offer?
  • How will clients use the finished product?

By answering the above questions, you can narrow down your search for the appropriate metal stamping material. Since there are so many material options, it can be challenging to find the one with the exact characteristics you need. Because of this, it’s always a good idea to work with a trusted metal stamping manufacturer, as they have the necessary knowledge and experience to guide you toward the best material for your needs.

Copper Alloys for Metal Stamping

Copper and its alloys, like brass and bronze, have appealing characteristics that make them ideal for many metal stamping projects.

Steel Alloys Used in Metal Stamping

Steel lateral plate made from laser cuttingOne of the most commonly used metals for metal stamping is steel. However, not all steel alloys are alike, and each type has its own unique qualities. Selecting a steel alloy for a metal stamping project depends on the application’s specific requirements. The most common types of steel used for metal stamping include carbon steel, alloy steel, and stainless steel.

Types of Steel for Metal Stamping

When choosing the right steel for a metal stamping project, consider whether you want carbon, alloy, or stainless steel. The following offers a breakdown of their differences to help you determine which is suitable for your application.

Carbon Steel

Most applications that involve steel production use carbon steel. This metal contains various trace elements of different alloy products. Depending on your specific requirements, there are three subcategories of carbon steel, including:

  • High Carbon Steel. This carbon steel features carbon content comprising 0.60% to 1.4% of the total weight. While the high carbon content makes it the most durable of the carbon steel alloys, it’s also the least workable.
  • Medium Carbon Steel. Carbon contents for medium carbon steel are between 0.25% and 0.60% of the steel’s mass. This type of carbon steel is normally combined with other alloys such as chromium and molybdenum to increase its strength and resistance to wear.
  • Low Carbon Steel. Low carbon steels feature carbon contents of 0.03% to 0.08%. The low carbon content makes them highly resistant to corrosion, and they are far more workable than high carbon steel.

Alloy Steel

These steel materials are made with different types of alloying elements such as copper, titanium, nickel, aluminum, and manganese, which can change the properties of the steel. Some of these alloys may contribute to the metal stamping material’s overall strength, workability, weldability, and corrosion or overall wear resistance. Alloy steels are commonly used for a variety of parts, including transformers, electric motors, pipelines, and automotive parts.

Stainless Steel

Stainless steel is a type of steel alloy that contains approximately 18% chromium. This chromium content makes stainless steel both highly resistant to corrosion and visually appealing with a notable luster. Stainless steel is often more costly to use than other alloys, but the increased durability and corrosion resistance make it worth the higher price. Depending on your steel stamping needs, there are a few different stainless steel types available:

  • 301. This stainless steel features high tensile strength along with corrosion and rust resistance. It’s available in three subcategories including hard, half hard, and full hard.
  • 304. For products that need moderate tensile strength in addition to corrosion and rust resistance, 304 grade stainless steel is ideal. It’s frequently used for stainless steel disc stamping and various food-grade steel products.
  • 316 and 316L. This stainless steel grade serves as an enhanced version of 300 series stainless steel. This particular grade features molybdenum content that lends additional strength and corrosion resistance, and it’s often used for applications involving marine and pharmaceutical environments, along with food processing.

Sheet Metal Stamping Process

Stamped sheet metal parts

The process of turning sheets of metal into a useful part or component is called sheet metal stamping. The metal is fed into a press, where the stamping tool, also known as a die, creates the desired shape. The die is pressed into or through the metal with tremendous force. The force used in the process is measured in tons.
Except for some specialized processes, sheet metal stamping doesn’t use heat. Instead, it is done with a cold-forming technique. Even though no heat is used, the part can come out hot because of the friction that’s created between the metal and the die from the force of the press.

What Is Sheet Metal Stamping?

Common Sheet Metal Stamping Process

There are basically only three components to sheet metal stamping—the sheet metal, die, and press machine—but any single part can require multiple steps to arrive at its final form. The following guide explains a few common processes that might occur during metal stamping.

  • Forming: Forming describes the process of transforming the flat metal into another shape by applying force. It is accomplished in one of several ways, depending on the design specifications for the part. With a series of operations, the metal can be altered from a relatively simple shape into a complex one.
  • Blanking: Blanking is the most basic technique and initiates when the sheet or blank is fed into the press where the die cuts out the desired shape. The resulting piece is called a blank. The blank may be the desired part, also known as a fully finished blank, or it may continue to the subsequent step of forming.
  • Drawing: Drawing is a more complicated operation and is how vessels or deep depressions are formed. Tension is used to carefully draw the material into a cavity to change its shape. Though the material might stretch while it’s drawn, technicians try to avoid stretching as much as possible to keep the material intact. Sinks, cooking equipment, and oil pans for vehicles are usually made with drawing.
  • Piercing: Piercing is almost the opposite of blanking, but instead of saving the blanks, technicians use the material around the outside of the punched area. As an example, think of cutting biscuits from a rolled-out circle of dough. During blanking, the biscuits are saved; during piercing, on the other hand, the biscuits are discarded, and the hole-riddled remains are the desired outcome.

Materials

Though virtually any metal, including gold, can be stamped, sheet metal is by far the most common. The type of metal used depends on the type of part that’s needed and its desired properties, such as corrosion- and heat-resistance.

Sheet metal stamping can produce parts from the following materials:

Applications of Sheet Metal Stamping

In the stamping process, sheet metal is transformed into complex parts using highly specialized computer-aided drafting and manufacturing programs. Sheet metal stamping produces superior, resilient, heavy-duty parts quickly and efficiently. The results are so precise, they’re typically more reliable and consistent than manual machining.

The following industries use components that are created via sheet metal stamping:

  • Automotive
  • Renewable energy
  • Medical
  • Industrial
  • Aerospace
  • Hardware
  • Home improvement

This list is by no means exhaustive. There is a considerable demand for sheet metal stamping, and the range of industries that depend on it is vast.

Aluminum Alloys Used in Metal Stamping

Radiator frame assemblyMetal stamping is a metalworking process used to form various parts and products from sheet metal. It accommodates a wide range of materials, including aluminum.

Aluminum is highly suitable for stamping operations due to its strength and workability. Stamped aluminum components find application in nearly every industry, including aerospace, automotive, electronics, marine, medical, and more. Below we provide an overview of the aluminum stamping process, including typical metal stamping materials employed and the properties they exhibit.

Commonly Used Aluminum Alloys in Metal Stamping Operations

For stamping operations, pure aluminum is often alloyed with other metals to add or enhance certain material properties to improve the performance of the end product. Typical alloying materials include copper, iron, magnesium, manganese, silicon, and zinc. Each alloy is assigned a unique four-digit number, the first digit of which is determined by the primary alloying element. For example:

  • 1xxx is used for 99% pure aluminum with no alloying element
  • 2xxx is used for aluminum alloyed with copper
  • 3xxx is used for aluminum alloyed with manganese
  • 4xxx is used for aluminum alloyed with silicon
  • 5xxx is used for aluminum alloyed with magnesium
  • 6xxx is used for aluminum alloyed with magnesium and silicon
  • 7xxx is used for aluminum alloyed with zinc
  • 8xxx is used for aluminum alloyed with other elements

The four-digit number may also include a letter tagged onto the end. This letter is indicative of the alloy’s temper designation. For example, fabricated is represented by F, annealed is represented by O, strain hardened is represented by H, solution heat-treated is represented by W, and heat treated (not applicable to F, O, or H designations) is represented by T.

Some of the most commonly used aluminum alloys in metal stamping operations are:

  • 1100: This commercially pure aluminum exhibits high ductility, material softness, and workability. It is ideal for forming operations involving intricate part or product designs, such as for flatware or decorative components.
  • 3003: This aluminum-manganese alloy has greater strength than aluminum 1100. It also demonstrates good corrosion resistance and workability. Some of its typical applications include cooking instruments, kitchen equipment, and chemical handling products.
  • 5052: This aluminum-magnesium alloy has higher strength than any of the other common non-heat-treatable variations. It also offers better fatigue strength, high corrosion resistance, and good workability and finishing characteristics. Typical use cases include aircraft parts, home appliances, and heavy-duty cooking implements.
  • 6061: This aluminum alloy is heat treatable. It is highly versatile due to its numerous advantageous mechanical and chemical properties, including corrosion resistance, formability, and weldability. It is widely used for making structural parts such as the bodies and frames of automobiles.
