According Cu-Zn binary state (Figure 6), there are three brass tissue temperature: less than 35% zinc content in brass microstructure at room temperature by a single α-phase solid solution composition, called α yellow copper; zinc content in the range of 36% to 46% of the brass, the microstructure at room temperature by the (α + β) two-phase, called the (α + β) brass (two-phase brass); containing more than 46% zinc and 50% brass, room temperature microstructure consists of only phase β, called β brass. (2) single-phase pressure processing performance α brass (from H96 to H65) with good ductility, can withstand hot and cold processing, but the α single-phase brass prone to embrittlement in the temperature in the hot forging process, the specific temperature range with Zn-containing different amounts vary, generally between 200 ~ 700 ℃. Therefore, when the thermal processing temperature should be above 700 ℃. The main reason for the single-phase α brass brittle zone temperature generated in the Cu-Zn alloy system α phase region exists Cu3Zn and Cu9Zn two ordered compounds, occurs when the low temperature heating orderly transition of the alloy brittle; addition alloy in the presence of trace amounts of lead, bismuth and copper harmful impurities form low melting point eutectic films distributed in the grain boundaries, intergranular fracture during thermal processing. Practice shows that the added amount of cerium can be effectively eliminated in the temperature brittleness. Two-phase brass (from H63 to H59), in addition to having plastic alloy good α-phase, but also by the emergence of electronic compounds β CuZn-based solid solution. β-phase having a high ductility at high temperature, low temperature and the β 'phase (ordered solid solution) hard and brittle nature. Therefore, (α + β) brass forged in the hot state. Greater than 46% zinc and 50% of β brass brittle because of performance, the pressure can not be processed. (3) the mechanical properties of brass, zinc content, the mechanical properties are not the same, FIG 7 is a brass mechanical properties change with the zinc content of the curve. For α brass, with the increase in zinc content, σb and δ are constantly increased. For the (α + β) brass, when the zinc content increased to about 45%, room temperature strength continues to increase. If more further increase the zinc content, since the greater to the alloy brittle r phase (Cu5Zn8 compound group in solid solution), drastically reduced strength. (Α + β) brass is always room temperature ductility with increasing zinc content decreases. So more than 45% of the zinc-zinc alloy no practical value. Ordinary brass extremely versatile
