Copper is a relatively pure copper, generally can be approximated as pure copper. It’s better conductivity and plasticity, but the strength and hardness is ideal.
According to the composition, China's copper production materials can be divided into four categories: ordinary copper, oxygen-free copper, oxygenated copper and special copper which increase a few alloying elements (such as arsenic copper, tellurium copper, silver copper) . Copper's electrical and thermal conductivity is second only to silver, and it is widely used in the manufacture of electrically and thermally conductive devices.
Brass rod is a rod shaped object made of copper and zinc alloy, named for its yellow color. Brass rod has good mechanical properties and wear resistance. It is mainly used in the manufacture of precision instruments, ship parts, auto parts, medical accessories, electrical accessories and all kinds of mechanical auxiliary materials, automotive synchronizer tooth rings.
