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、Tin brass:Adding tin to brass can significantly improve the heat resistance of the alloy, especially the ability to improve the corrosion resistance of seawater, so tin brass is called "navy brass".
Tin can be dissolved into copper - based solid solution and play the role of solid solution strengthening. However, with the increase of tin content, brittle r phase (CuZnSn compound) will appear in the alloy, which is not conducive to the plastic deformation of the alloy, so the tin content of tin brass is generally in the range of 0.5% ~ 1.5%.Commonly used tin brass are HSn70-1, HSn62-1, HSn60-1 and so on. The former is an α alloy with high plasticity and can be processed by cold or hot pressure. The latter two types of alloys have (α+β) two-phase microstructure, and often a small amount of r phase, not high plasticity at room temperature, can only be deformed in the hot state.
3、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.
4、Iron brass：In iron brass, iron is precipitated by iron-rich particles, which is used as the crystal nucleus to refine the grain, and can prevent the recrystallization grain growth, so as to improve the mechanical properties and technological properties of the alloy. Iron brass usually contains less than 1.5% iron, and its structure is (α+β). It has high strength and toughness, good plasticity at high temperature, and deformation at cold state. The common brand is Hfe59-1-1.
