Brass is an alloy of copper and zinc. If only brass made of copper and zinc is called ordinary brass. Brass is often used in the manufacture of valves, water pipes, air-conditioning inside and outside machine connecting pipes and radiators. A better understanding of the properties of brass is of great importance for the use of brass and the development of the brass industry.


Mechanical properties of ordinary brass properties: The mechanical properties of brass are different due to the different zinc content. Figure 7 shows the mechanical properties of brass as a function of zinc content. For alpha brass, as the amount of zinc increases, both σb and δ increase. For (α+β) brass, the room temperature strength is continuously increased before the zinc content is increased to about 45%. If the amount of zinc is further increased, the r phase having a greater brittleness (solid solution based on a Cu5Zn8 compound) appears in the alloy structure, and the strength is drastically lowered. The room temperature ductility of (α+β) brass always decreases with increasing zinc content.


The performance of special brass: the α phase and the β phase in special brass are multi-component complex solid solution, and the strengthening effect is large, while the α and β phases in ordinary brass are simple Cu-Zn solid solution, and the strengthening effect is low. . Although the zinc equivalent is equivalent, the properties of the multiple solid solution are not the same as those of the simple binary solid solution. Therefore, a small amount of multi-component strengthening is a way to improve the properties of the alloy.


Lead brass characteristics: Lead is practically insoluble in brass and is distributed on the grain boundaries in the form of free particles. Lead brass has two kinds of α and (α+β) according to its structure. Because of the harmful effects of lead, alpha lead brass is very low in temperature and plasticity, so it can only be cold deformed or hot extruded. (α+β) lead brass has good plasticity at high temperatures and can be forged. Tin Brass: The addition of tin to brass can significantly improve the heat resistance of the alloy, especially the ability to resist seawater corrosion. Therefore, tin brass is known as “navy brass”.


Manganese Brass Properties: Manganese has a greater solubility in solid brass. Adding 1% to 4% manganese to brass can significantly improve the strength and corrosion resistance of the alloy without reducing its plasticity.


Characteristics of iron brass: In iron brass, iron precipitates as iron-rich phase particles, which acts as crystal nuclei to refine grains and prevent recrystallized grains from growing, thereby improving the mechanical properties and process properties of the alloy. The iron content in iron brass is usually below 1.5%, its structure is (α+β), it has high strength and toughness, it is very plastic at high temperature, and it can be deformed in cold state. The commonly used grade is Hfe59-1-1.


Nickel Brass Properties: Nickel and copper form a continuous solid solution, significantly expanding the alpha phase region. The addition of nickel to brass significantly improves the corrosion resistance of brass in the atmosphere and seawater. Nickel also increases the recrystallization temperature of the brass, which promotes the formation of finer grains. HNi65-5 nickel brass has a single-phase α structure, which has good plasticity at room temperature and can also be deformed in the hot state.
