Metal stamping is a cold forming process that uses dies and punches to stretch and form sheet metal into a specified shape. The metal stamping process involves placing flat metal in blank form into a stamping machine. In a press, a punch pushes the metal into a die, turning the metal into a finished part.

The most common metals in metal stamping include aluminum, stainless steel, mild steel, copper and brass.

aluminum

Aluminum is a non-ferrous metal that is relatively inexpensive and has an excellent strength-to-weight ratio, making parts durable, strong, and lightweight. Another advantage of using aluminum in metal stamping is that it is corrosion-resistant and non-toxic. It has the added benefit of not requiring a coating during finishing, although it can be anodized to enhance its appearance and improve its corrosion resistance. The lightweight strength of aluminum is critical to the automotive and aerospace industries, where eliminating excess weight can improve fuel economy.

Stainless steel

Stainless steel is a ferrous metal that contains large amounts of chromium, molybdenum and nickel. Stainless steel offers desirable properties for metal stamping, including corrosion resistance, non-magnetic properties, very good wear resistance, no need for electroplating, and heat treatability.

Stainless steel is often the material of choice for metal stampings when used in the aerospace and defense, lawn and garden sealing equipment, and plumbing and valve industries.

Low-carbon steel

There are two types of low carbon steel materials: flat and coil. Mild steel offers several benefits for metal stamping, including as a low-cost, high-strength material. It can be used to manufacture a wide variety of parts at a lower unit price. Mild steel is a very durable metal commonly used in sealing technology, automotive, lawn and garden applications.

copper and brass

Copper is easy to form, ideal for rapid production of one-piece seamless components, and is compatible with the cold forming process, which hardens the metal. Copper is a corrosion-resistant, low-maintenance, durable metal with natural hygienic properties for use in the medical, food and beverage industries.

Brass is a copper-zinc alloy that retains many of the beneficial properties of copper. Brass has a smooth surface, resists corrosion and provides electrical conductivity, making it suitable for a wide range of electronic applications.

Choosing the Right Material for Deep Drawing Metal Stamping

Adaptable and efficient deep drawing metal stamping is a metal forming method suitable for parts with high depth to diameter measurements and large volumes. A variety of metals can be used in the deep drawing process. At Paveto Stamping, we can produce high quality deep drawn parts from a variety of metals as summarized below.

Stainless Steel 304, 305, 310, 316 – Stainless steel is an ideal material for a variety of applications, offering a range of corrosion, high and low temperature resistance properties, as well as high strength, great aesthetics and ease of manufacture.
Cold Rolled Steel 1008-1010 – Cold rolled steel offers good ductility, good strength and versatility for a variety of coatings at a very low cost.
Aluminum 1100, 2024, 3003, 5052, 6061 – These aluminum alloys have good drawability, good corrosion resistance and low cost. Aluminum 6061-0 can be heat treated for high strength.
Brass 85/15 and 70/30 – Brass 85/15 (red brass) and 70/30 (yellow cartridge brass) have good stretchability and weldability.
Copper C110 – Copper is corrosion resistant, particularly ductile, and offers very good dimensional repeatability. Due to the softness of copper, different wall thicknesses can be achieved.
Nickel Silver – Corrosion resistance, high electrical conductivity, elasticity and strength, excellent ability to weld, stamp or etch.
The benefits of using the deep drawing metal stamping process

Deep drawing metal stamping offers several significant manufacturing advantages, as it can quickly and economically mass produce simple, complex or complex parts while adhering to strict design specifications with high precision.
