ProductsRaw Materials

Raw material of production of copper and copper alloys includes ingots such as electrolytic copper and zinc and scrap. Scrap may be, again, divided into lumps produced from manufacturing process, chips in the form of powder scattered from cutting work and waste products after use. Copper alloy industry should be basically termed recycling industry in view of the fact that such scrap is to be collected to be melted, together with electrolytic copper and zinc ingots, then to be cast; it is also a pro-environment industry from the point of view of the recent Green Round regime that globally puts a special emphasis on importance of resources recycling. In conclusion, copper alloy industry is a processing one in which coper, as main material, is melted and cast together with zinc, lead, tin, nickel, etc., as subsidiary materials, and processed via pressing, extruding, drawing, etc., to be final products including plate, tape, rod, pipe, wire, etc.
