Imports of metallic copper, copper ingots, copper rod, copper strip, copper powder, copper strip long-term supply of imported metal copper, copper ingots, copper rod, copper strip, copper powder, copper bars, copper chloride, pure copper, bronze powder, brass powder, standard copper cathodes, high purity copper cathode, copper hydroxide, copper oxide, copper acetate, copper sulfate, copper cathodes, symbol: Cu; color: red; density: 8.96, metallic copper, atomic weight 63.54, specific gravity 8.92 melting point 1083Co. Pure copper pale rose or pink. Copper has many valuable physical and chemical properties, for example, have a high thermal conductivity, chemical stability, tensile strength, easy to weld, and corrosion resistance, plasticity, ductility. The pure copper can be pulled into the very fine copper wire, made of a thin copper foil. With zinc, tin, lead, manganese, cobalt, nickel, aluminum, iron and other metals to form an alloy, forming the alloy is mainly divided into three categories: the brass is a copper-zinc alloy, bronze is a copper-tin alloy, copper-nickel alloy is a copper-cobalt-nickel alloy.
