Varied metals and metal alloys can be formed into sheets and used to fabricate sheet metal parts. The choice of materials depends on the requirements of the application and factors in material selection include:
Stand and spring-like stainless steel are the two categories used in sheet metal fabrication.
The process of cold rolling steel is used to smooth the finish of hot rolled steel as well as to hold a tighter tolerance when forming. CRS is available in 1008 and 1018 alloys.
This sheet metal material is either hot-dip galvanized steel or galvannealed steel, which is galvanized and then annealed.
A moderately-priced material, aluminum has a range of characteristics across several grades to meet application requirements. Grade 1100 offers relatively low strength but is chemical and weather-resistant, and weldable and ductile, allowing deep drawing. Grade 3003 is stronger and formable, weldable, corrosion-resistant, and affordable. Grade 5052 is significantly stronger while still formable, weldable, and corrosion-resistant. Grade 6061 is a structural alloy that is corrosion-resistant and strong, but not formable. It is weldable, though it sacrifices some strength when welded.
Designers and engineers who want a “red” metal typically choose electrolytically tough pitch (ETP) copper, either C110 or C101. In less frequent cases, cartridge brass is used as an alternative.
