Introduction to various copper alloys

Brass

Brass is a copper alloy of copper and zinc, named after the yellow color. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, and shells for guns. Brass knocks up and sounds good, so instruments such as cymbals, cymbals, bells, and numbers are made of brass.


Nautical brass

Copper alloy with zinc and tin, resistant to seawater erosion, can be used to make ship parts and balancers.


Bronze

The alloy of copper and tin is called bronze, which is named for its color. Bronze generally has good corrosion resistance, wear resistance, castability and excellent mechanical properties. It is used to manufacture precision bearings, high-pressure bearings, mechanical parts resistant to seawater corrosion on ships, and various plates, pipes, bars, etc. Bronze also has an anomalous property - "heat shrinking and cold expansion", which is used to cast a statue, and expands after cooling to make the eyebrows clearer.


Phosphor bronze

The alloy of copper with tin and phosphorus is hard and can be made into spring.


White copper

White copper is an alloy of copper and nickel. Its color is the same as silver, and its silver is shiny and not easy to rust. Often used in the manufacture of electrical appliances, instruments and decorations.
