  1.QSn6.5-0.1, QSn6.5-0.4, QSn7-0.2, QSn8-0.3, US standard C51900, C52100

  It has high strength, elasticity, wear resistance and magnetic resistance, good workability under hot and cold pressure, high flame resistance to electric spark, weldability and fibre welding, good machinability, corrosion resistance in air and fresh water. Widely used in the manufacture of elastic components. Wear-resistant parts and antimagnetic parts in precision instruments, such as gears, brush boxes, vibrating discs, contactors, washers, small shafts

  2. QSn6-6-3. QSn5-5-5, US standard C83600, C93200, C54400

  Medium strength, good wear resistance and corrosion resistance, excellent cutting performance. Mainly used for wear-resisting and corrosion-resisting parts under high load and medium sliding speed, such as bearing bush, bushing, cylinder liner, piston clutch, pump cover and worm wheel, etc.

  3. ZCuSn10Pb1, CuSn12 US Standard C52400

  It has high hardness, excellent wear resistance, not easy to bite, good casting and cutting performance, and good corrosion resistance in air and fresh water. Usually used for wear-resistant parts under high load and high sliding speed, such as connecting rod, bushing, bearing bush, gear, sleeve, worm wheel, etc. Zhangjiagang Hengxinda Machinery Co., Ltd. produces copper sleeve, Jiangsu copper sleeve manufacturer

  4. QAl9-4, QAl10-3-1.5, QAl10-4-4, CuAl10Fe3, ZCuAl9Fe4Ni4Mn2, US Standard C95400, C61900, C95800

  It has high strength and good cutting and grinding performance. It can be welded and easy to be hot-worked. Mainly used for manufacturing high strength sleeve, spherical seat, booster slider, guide screw, driven shaft, support ring, connecting rod, nut and gear etc. 5. Lead bronze ZCuPb10Sn10, ZCuPb15Sn8, American standard C93700, C93800.

  Lubrication, wear resistance and corrosion resistance are good. Manufacture of sliding bearings with high surface pressure and side pressure, such as rollers, vehicle bearings, impact parts with peak load up to 60 Mpa, bimetallic bearing bushes of internal combustion engines with peak load up to 100 Mpa, piston pin sleeves and friction discs

  6. High-strength brass ZCuZn25Al6Mn3Fe3, US standard C86300

  High strength brass has the highest strength among special brass. It has high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used to cast high load wear-resistant copper sleeve on heavy machinery, and it is commonly used as oil-free self-lubricating bearings.
