Copper alloys exist in more than 400 varieties. Each copper alloy variety has specific properties that suit a number of manufacturing processes, environments and applications.

Carbon steels are steels that contain only carbon as their major alloying element. These steels also contain small quantities of copper, nickel, molybdenum, aluminium and chromium. Traces of 0.4% silicon and 1.2% manganese can also be found in these steels.
Steels of the type A2, A3, A4, A6, A7, A8, A9, and A10 are known as air-hardening, medium alloy, cold work steels or group A steels.
Carbon steels are steels having carbon as primary alloying element. They are designated by AISI four-digit numbers. They also contain 0.4% silicon and 1.2% manganese.
Steels containing mostly carbon as the alloying element are called carbon steels. They contain about 1.2% manganese and 0.4% silicon.
Air-hardening, medium alloy, cold work steels or group A steels include the A2, A3, A4, A6, A7, A8, A9, and A10 steels.

Low-carbon mold steels or group P steels comprise different types that include P2, P3, P4, P5, P6, P20, and P21 steels. Chromium and nickel are the main alloying elements found in group P steels.
Alloy steels comprise a wide range of steels having compositions that exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C allocated for carbon steels. In comparison with carbon steels, alloy steels are a lot more responsive to mechanical and heat treatments.
