Copper and copper alloys
Copper is divided into four categories according to its alloy system: red copper (pure copper), brass, bronze and white copper.
Red copper includes ordinary pure copper, oxygen-free copper, phosphorus deoxidized copper, silver copper, etc.
Brass refers to a copper alloy with zinc as the main added element, which is divided into ordinary brass and complex brass. Complex brass includes lead brass, aluminum brass, tin brass, iron brass, silicon brass, manganese brass, and nickel brass.
Bronze refers to copper alloys with other elements besides zinc and nickel as the main added elements, including tin brass, beryllium bronze, aluminum bronze, silicon brass, magnesium bronze, titanium bronze, chromium bronze, zirconium bronze and cadmium bronze, etc.
Cupronickel refers to copper alloys with nickel as the main added element, including ordinary cupronickel, iron cupronickel, zinc cupronickel, aluminum cupronickel, etc.
