High strength brass copper sets Chemical composition:

High strength brass chemical formula for ZCuZn24Al6Fe4Mn3, copper content of about 65%, about 24% zinc. Aluminum can improve the strength, hardness and corrosion resistance of brass. Brass room temperature organization has three kinds: zinc content of 35% in the following brass, room temperature microstructure from the single-phase α solid solution composition, known as α brass; mainly used for ordinary copper and self-lubricating copper sets The

High strength brass copper sleeve mechanical properties:

High strength brass copper sets of different zinc content, mechanical properties are not the same, for α brass, with the increase in zinc content, σb and δ are increasing. So zinc content of more than 45% of copper and zinc alloy is of no practical value. Standard high strength brass Brinell hardness HB greater than 200, compressive strength greater than 600MPa, elongation greater than 10%.

High strength brass copper sleeve pressure processing performance:

High-strength brass copper sets have good plasticity, can withstand hot and cold processing, but in the forging and other hot processing prone to moderate temperature brittleness, the specific temperature range with the amount of Zn varies, generally in the 200 ~ 700 ℃ between. Therefore, the thermal processing temperature should be higher than 700 ℃.
