Stamping Aluminum Sheet Metal

Ironing is the basic process used to make beverage cans see figure 2.

Stamping aluminum sheet metal.

Providing sheet metal having opposite major surfaces and being made of steel aluminum or any other desired elemental or alloyed metal. Stamping includes a variety of sheet metal forming manufacturing processes such as punching using a machine press or stamping press blanking embossing bending flanging and coining. Aluminum metal stamping is a cold working process that utilizes work hardening of the material to accentuate the metal s beneficial qualities.

Aluminum parts that have been stamped provide greater physical strength than unworked raw aluminum material. After the desired thickness is obtained the sheet metal then is rolled into a large coil. Stamping also known as pressing is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. It features high electrical conductivity advanced corrosion resistance and easy work ability.

2024 aluminum alloyed with copper for applications that require high strength to weight ratio and strong fatigue resistance. The method comprises providing a paint film. Pieces of flat sheet metal typically referred to as blanks is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape. When aluminum is ironed it almost compressively flows like a hot liquid down the wall of the die cavity and punch and it shines to a mirrorlike surface finish.

Metal stamping is a cold forming process that makes use of dies and stamping presses to transform sheet metal into different shapes. Laminating the paint film onto a major surface of the sheet metal to form a painted sheet metal laminate comprising a first portion and a second portion. Aluminum is a silvery white metal that has comparable strength to carbon steel but at roughly one third the density. 1100 aluminum a strong alloy considered commercially pure aluminum.

Since the sheet metal has thickness of 019 inches there must be a gap between the two dies that allows the sheet metal to fit during the stamping process. This alloy is very ductile and malleable making it ideal for precision stamping processes. 3003 aluminum a general purpose alloy commonly used in sheet metal applications. Although most stamping operations use sheet steel special dies can cut and form steel bars up to 3 in.

Typical sheet metal thicknesses used in stamping are 0 001 in.
