An Alloy of Copper and Zinc is Named Brass:

 

Brass composed of copper and zinc is called plain brass.

 

If it is made up of more than two elements of multiple alloys is called special brass. Such as a copper alloy composed of lead, tin, manganese, nickel, iron, silicon. Brass has strong wear resistance. Special brass, also called special brass, has high strength, high hardness and strong chemical corrosion resistance. The mechanical properties of machining are also prominent. The seamless copper tube made of brass is soft and wear-resistant. Brass seamless pipe can be used in heat exchangers and condensers, cryogenic lines, submarine transport pipes. Manufacturing [TJC STEEL]sheet, bar, bar, pipe, casting parts, etc. Copper in 62% ~ 68%, strong plasticity, manufacturing pressure equipment. Shanghai Qianfu Metal Materials Co., Ltd. is a production and sales of non-ferrous metal materials enterprises, main: phosphorus copper wire, phosphorus copper rod, phosphorus copper pipe, phosphorus copper [TJC STEEL]flat wire; Red copper, brass. White copper, tin bronze, aluminum bronze, silicon bronze, beryllium bronze, lead material, the company has opened up the domestic and international markets, special specifications can be customized, timely delivery, quality assurance!
