Brass is an alloy of copper and zinc
White copper is an alloy of copper and nickel
Bronze is an alloy of copper and elements other than zinc and nickel, mainly tin bronze, aluminum bronze, etc.
Copper is a copper with a high copper content, and the total content of other impuritiesisbelow1%.
Copper is pure copper, also known as copper. The density of pure copper is 8.96 and the melting point is 1083 °C. It has good electrical conductivity and thermal conductivity, excellent plasticity, easy to hot and cold pressure processing, and is widely used in the manufacture of wires, cables, brushes, electro-etched copper for electric sparks and other products requiring good electrical conductivity.
Named after the purple color. It is not necessarily pure copper, and sometimes a small amount of deoxidizing elements or other elements are added to improve the material and properties, so it is also classified as a copper alloy. Chinese copper processing materials can be divided into: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), adding a small amount of alloy Elemental special copper (arsenic copper,berylliumcopper,silvercopper)fourcategories.

The copper alloy with zinc as the main additive element has a beautiful yellow color, collectively referred to as brass. The copper-zinc binary alloy is called ordinary brass or simple brass. Brass with more than three yuan is called special brass or complex brass. Brass alloys containing less than 36% zinc are composed of solid solution and have good cold workability. For example, brass containing 30% zinc is commonly used to make bullet casings, commonly known as cartridge brass or seven-three brass. Brass alloys containing between 36 and 42% zinc are composed of solid solution, the most common of which is 40% brass with 40% zinc.
