The brass rod is a rod-like object made of an alloy of copper and zinc.It is named after its yellow color. Brass rods have good mechanical properties and wear resistance. They are mainly used to manufacture precision instruments, ship parts, gun shells, auto parts, medical parts, electrical parts, and various mechanical supporting materials, automobile synchronizer teeth Ring and so on.

Red copper is a relatively pure type of copper, which can generally be approximated as pure copper.It has good electrical conductivity and plasticity, but its strength and hardness are relatively poor. At present, my country's copper processingmaterials can be divided into: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP), adding a small amount of alloying elements Four types of special copper (arsenic copper, tellurium copper, silver copper). Since the electrical conductivity and thermal conductivity of copper are second only to silver, copper rods are mainly used to make electrical and thermal equipment.

Cupronickel rod is a copper alloy with nickel as the main alloying element, and is a continuous solid solution formed by Cu and Ni. Ordinary cupronickel rods have good corrosion resistance, medium strength, high plasticity, cold and hot pressure processing, and good electrical properties. In addition to being used as structural materials, they are also important high-resistance and thermocouple alloys.
