Knowledge introduction of various copper alloys
brass
Brass is a copper alloy of copper and zinc, named for its yellow color. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, parts of ships, shell casings of guns, etc. Brass sounds nice when knocked, so musical instruments such as gongs, cymbals, bells, and horns are all made of brass.
nautical brass
An alloy of copper, zinc, and tin is resistant to seawater erosion and can be used to make ship parts and balancers.
bronze
The alloy of copper and tin is called bronze, named for its blue color. Bronze generally has good corrosion resistance, wear resistance, castability and excellent mechanical properties. Used in the manufacture of precision bearings, high pressure bearings, seawater corrosion-resistant mechanical parts on ships, and various plates, pipes, bars, etc. Bronze also has an anomalous property - "heat shrinks and expands with cold", which is used to cast statues and expands after cooling, which can make eyebrows clearer.
Phosphor bronze
The alloy of copper, tin and phosphorus is hard and can be used to make springs.
Cupronickel
Cupronickel is an alloy of copper and nickel. Its color is the same as that of silver. It is shiny silver and not easy to rust. Commonly used in the manufacture of electrical appliances, instruments and decorations.
