brass plate classification
1、Lead brass：Lead is actually insoluble in brass and distributed on the grain boundary as a free particle. Lead brass can be divided into α and (α+β) according to its structure. α lead brass due to the harmful effect of lead, high temperature plasticity is very low, so it can only be cold deformation or hot extrusion. (α+β) lead brass has good plasticity at high temperature and can be forged. 2、Manganese brass:Manganese has a greater solubility in solid brass. The strength and corrosion resistance of brass alloy can be significantly improved by adding 1% ~ 4% manganese without reducing its plasticity.Manganese brass with (α+β) structure, commonly used HMn58-2, cold and hot state pressure processing performance is quite good.
