    The selection of surface treatments for copper and copper alloys is generally based on application requirements for appearance and corrosion resistance. This article describes cleaning, finishing, and coating processes for copper and copper alloys. For the other materials, such as copper, brass, aluminum and C45 carbon steel, corrosion rates were similar. None of the materials was affected by corrosion to a significant degree, which was assessed as corrosion resistance grade 2 – materials with high corrosion resistance – Table by: 2.

Breedis, in Encyclopedia of Materials: Science and Technology, (b) Coefficient of thermal expansion (CTE) All copper alloys expand by nearly the same amount as they are heated; this behavior is a consequence of interatomic bonding in the copper alloy matrix structure.

Unlike iron–nickel alloys, copper cannot be alloyed to significantly alter the CTE property. Chromium Copper is the primary copper alloy for high level production spot and seam welding of clean mild steel, low alloy steels, stainless steel, low conductivity brasses and bronzes, nickel-silver, nickel, nickel alloys, and monel.
