Brass
Brass is an alloy of copper and zinc, named for its yellow color. Brass has good mechanical properties and wear resistance, and can be used to make precision instruments, ship parts, gun shells and so on. Brass sounds good when struck, so gongs, cymbals, bells, horns and other musical instruments are made of brass.
Nautical brass
An alloy of copper, zinc and tin, it 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 green color. It was a common alloy in ancient times (e.g. Bronze Age in China). 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, as well as a variety of plates, tubes, rods and so on. Bronze also has a perverse property – “heat shrinkage and cold expansion”, used for casting statues, expansion after cooling, can make the brow clearer.
Phosphor Bronze
An alloy of copper with tin and phosphorus, hard enough to make springs.
White Bronze
White copper is an alloy of copper and nickel, its color and silver, silver, not easy to rust. It is often used to make coins, electrical appliances, instruments and decorations.
18K Gold (18K Gold or Rose Gold)
An alloy of 6/24 copper and 18/24 gold. Reddish yellow in color and hardness, it can be used to make jewelry and decorations.
