H62 brass tube chemical composition: 　　 copper Cu: 60.3 antimony Sb: ≤0.08 　 boron P: ≤0.2～30 　　 heat treatment specification: hot working temperature 650～850℃; annealing temperature 600 ～700℃; low temperature annealing temperature to eliminate internal stress 270～300℃.Brass is an alloy of copper and zinc Brass is an alloy of copper and zinc; the simplest brass is copper-zinc binary alloy, called simple brass or ordinary brass.08 　　 lead Pb: ≤0. By changing the content of zinc in brass, brass with different mechanical properties can be obtained.5 phosphorus P: ≤0.01 bismuth Bi: ≤0. In order to improve certain performance of brass, brass with other alloy elements added on the basis of one-yuan brass is called special brass.5 　 　 zinc Zn: residual lead Pb: ≤0.0～60.15 　　

beryllium Sb: ≤0.2～30mm) 　　 Grade: H62 　　 Standard: GB/T 1527-1997 　　Characteristics and scope of application: 　　 has good mechanical properties, good plasticity in hot state, acceptable plasticity in cold state, good machinability , Easy fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; adding aluminum to manganese brass can also improve its performance and obtain a smooth surface casting. The higher the zinc content in brass, the higher its strength and the slightly lower plasticity. H59 brass standard: GB/T 2041-1989 Characteristics and Copper Tape For Transformer scope of application: 　　

H59 is the cheapest brass with high strength, hardness and good plasticity, but it can still withstand pressure processing and corrosion resistance under hot conditions Generally, other properties are similar to H62.003 Note: ≤1. H59 brass chemical composition: 　　 copper Cu: 57. The zinc content of brass used in the industry is not more than 45%, and even higher zinc content will produce brittleness and deteriorate the performance of the alloy. Tin can also improve the cutting performance of brass. Phosphorus copper belt Phosphorus copper belt Brass belt 1 Brass belt 2.002 　≤0. Brass can be divided into two types of products: casting and pressure processing.01 　 iron Fe: ≤0.0 (impurity) gravity Properties:
