The lead content of environmental protection in China is within 300ppm

The lead content of EU environmental protection is within 90ppm

Main features:

The brass strip has strong wear resistance. It has high strength, hardness and chemical corrosion resistance. In addition, the machining mechanical properties are also prominent. Brass has very good plasticity (the best of brass) and high strength, good machinability, easy welding, very stable to general corrosion, but prone to corrosion cracking; Brass Belt is an alloy of copper and zinc, named for its yellow color.

Purpose:

The mechanical properties and wear resistance of brass belt are very good. It can be used to manufacture precision instruments, ship parts, gun shells, shrapnel, metal stamping, etc. Brass sounds good, so gongs, cymbals, bells, trumpets and other musical instruments are made of brass. According to the chemical composition, brass is divided into ordinary copper and special brass.
