The materials of copper sculptures mainly include the following:
Bronze: Bronze refers to copper alloys other than copper-nickel alloys and copper-zinc alloys. The main types are tin bronze, aluminum bronze and special bronze (also known as high copper alloys).
Red copper: Red copper has good conductivity and ductility, but low strength and hardness. Red copper contains very few other components and can usually be identified as pure copper.
Brass: Brass is an alloy composed of copper and zinc, which can be divided into simple brass and complex brass. Complex brass may contain a third component, such as nickel brass, silicon brass, etc.
White copper: White copper refers to copper-nickel alloy, a copper-based alloy with nickel as the main additive, which is silvery white and has a metallic luster.
