Hollow brass rod is a kind of non-ferrous metal processing rod, which has good processing performance and high conductivity. Mainly divided into brass rods (copper-zinc alloy, cheaper), copper rods (higher copper content). Hollow brass rod is a rod-like object made of the alloy of copper and zinc, named for its yellow color. The melting point of brass with 56% to 68% copper content is degree. Brass has good mechanical and wear resistance, and can be used to manufacture precision instruments, ship parts, shell of guns and so on. Zinc content is different, there will be different colors, such as 18% - 20% of zinc content will be red and yellow, and 20% - 30% of zinc content will be brown. In addition, brass sounds unique, so the gongs, cymbals, bells, horns and other instruments in the East, as well as brass wind instruments in the West are made of brass.

Tin bronze is a non-ferrous metal alloy with the smallest shrinkage. It is used to produce castings with complex shape, clear outline and low air tightness. Tin bronze is very corrosion resistant in atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and marine parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear-resistant and elastic parts of high precision working mothers. Lead-tin bronze is often used as wear-resistant parts and sliding bearings. Zinc tin bronze can be used as high air tightness casting!
