α single-phase brass (from H96 to H65) has good plasticity and can withstand hot and cold processing, but α single-phase brass is prone to moderate temperature brittleness during hot processing such as forging. The specific temperature range varies with the amount of Zn, generally between 200 and 700℃. Therefore, the temperature should be higher than 700℃ during hot working. The reason for the occurrence of mid-temperature brittle zone in single-phase α-brass is that there exist two ordered compounds, Cu3Zn and Cu9Zn, in the α-phase zone of Cu-Zn alloy system. In addition, trace harmful impurities of lead and bismuth in the alloy form low melting point eutectic films with copper, which are distributed on the grain boundary, resulting in intergranular fracture during hot working. The practice shows that adding a trace of cerium can effectively eliminate the middle temperature brittleness.
In two-phase brass (from H63 to H59), in addition to α phase with good plasticity, β solid solution based on electronic compound CuZn appears in the alloy structure. The β phase has high plasticity at high temperature, while the β 'phase (ordered solid solution) at low temperature is hard and brittle. Therefore (α+β) brass should be forged in hot state. β brass with zinc content of more than 46% ~ 50% can not be processed by pressure because of its hard and brittle properties.
For alpha brass, both σb and δ increase with the increase of zinc content. For (α+β) brass, the strength at room temperature increases until the zinc content increases to about 45%. If the zinc content is further increased, the strength of the alloy decreases sharply due to the appearance of more brittle r phase (solid solution based on Cu5Zn8 compound) in the microstructure. The room temperature ductility of (α+β) brass decreases with the increase of zinc content. So the copper zinc alloy containing more than 45% zinc has no practical value.
Common brass has a wide range of uses, such as water tank belt, water supply and drainage pipes, MEDALS, bellows, serpentine pipes, condensing pipes, shells and various shapes of complex punch products, hardware and so on. With the increase of zinc content from H63 to H59, they are well able to withstand hot processing, mostly used in mechanical and electrical parts, stamping parts and Musical Instruments.
