Carbon is the primary alloying element present in the carbon steels. They contain 0.4% silicon and 1.2% manganese. Small quantities of molybdenum, chromium, nickel, aluminium, and copper are also present in these steels.
Aluminum alloys are known for strong corrosion resistance. These alloys are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F), and tend to lose some of its strength.
Copper alloys are available in more than 400 varieties. Each copper alloy variety has specific properties that suit a number of manufacturing processes, environments and applications.
Aluminum alloys are known for their strong corrosion resistance characteristics and have high electrical conductivity. These alloys lose some of their strength when exposed to high temperatures and experience an increase in strength at subzero temperatures, and thus are good low-temperature alloys.
Copper beryllium alloys have high strength and good thermal and electrical conductivities. High conductivity alloys and high strength alloys are the two major types of copper beryllium alloys.
Copper casting alloy UNS C87300 is a cast alloy of copper and silicon. Brasses have attractive color and can be shaped according to the architects’ need.
Aluminum alloys contain have strong corrosion resistance characteristics and high electrical conductivity.
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. These steels contain elements such as chromium, cobalt, nickel, etc.

Alloy steels are designated by AISI four-digit numbers. They comprise different kinds of steels having compositions exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels.
Copper has the ability to be formed into alloys more freely than most metals, and can be combined with a broad range of alloying elements. This metal has excellent electrical and thermal conductivity of any commercial metal.
