Which elements can copper form alloy phases？
Brass is a copper alloy with zinc as the main additive element, which has a beautiful yellow color and is 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. Cupronickel is a copper alloy with nickel as the main additive element. The copper-nickel binary alloy is called ordinary cupronickel; the cupronickel alloy with manganese, iron, zinc, aluminum and other elements is called complex cupronickel. Bronze originally refers to copper-tin alloys, and later copper alloys other than brass and cupronickel are called bronzes, and are often given the name of the first main added element before the name of bronze. Tin bronze has good casting performance, anti-friction performance and good mechanical performance, and is suitable for manufacturing bearings, worm gears, gears, etc. Lead bronze is a widely used bearing material for modern engines and grinders. Aluminum bronze has high strength, good wear resistance and corrosion resistance, and is used for casting high-load gears, bushings, marine propellers, etc. Phosphor bronze has high elastic limit and good electrical conductivity, and is suitable for the manufacture of precision springs and electrical contact components. Beryllium bronze is used to manufacture non-sparking tools used in coal mines and oil depots. Beryllium copper is a supersaturated solid solution copper-based alloy with good mechanical properties, physical properties, chemical properties and corrosion resistance;
