Lead bronze bronze bushing, material grade C93800, corresponding to the domestic grade CuPb15Sn8, C93700, corresponding to the domestic grade, ZCuPb10Sn10 (10-10), this material in the lack of lubricants and with water lubricant conditions, sliding and self-lubricating performance, easy to cut, casting performance is poor, good corrosion resistance, high surface pressure, and side pressure bearings. Can be used to manufacture cold rolling mill copper cooling tube, shock load of up to 50Mpa parts, internal combustion engine bimetallic axle shaft tile, mainly used for large loads of up to 70Mpa piston pin bushing, acid-resistant fittings.

Tin bronze: tin as the main alloying element of the copper-based alloy called tin bronze, tin bronze in shipbuilding, chemical, machinery, instrumentation and other industries are widely used, mainly used in the manufacture of bearings, bushings and other wear-resistant parts and springs and other elastic components and corrosion-resistant, anti-magnetic parts, etc., with high strength, elasticity, abrasion resistance and anti-magnetism, in the hot state and cold state pressure machinability is good, the spark has a higher resistance to combustion, weldable and fibre welding, good machinability. Fibre welding, good workability, the main grades are ZCuSn6Zn6Pb3, ZCuSn10Pb5, ZCuSn5Zn5Pb5 and so on.

Lead bronze: lead as the main alloying element of copper-based alloys known as lead bronze, high friction reduction and good machinability, easy to weld and braze, in the atmosphere, fresh water has a good corrosion resistance, can only be in the cold state of pressure processing, because of the lead heat processing easily caused by thermal embrittlement, the production of friction conditions in the work of bearings, crimped bushings tin bronze for the addition of zinc, lead alloying elements of alloy copper, high friction reduction and good cutability, easy to weld and braze, main grades Pb15Sn7, Pb20Sn5, Pb10Sn10 and so on. High friction reduction and good machinability, easy to weld and braze, the main grades Pb15Sn7, Pb20Sn5, Pb10Sn10 and so on.

Aluminium bronze: aluminium as the main alloying element of copper-based alloys called aluminium bronze. The mechanical properties of aluminium bronze are higher than those of brass and tin bronze. Practical application of aluminium bronze aluminium content in 5% to 12% between the aluminium content of 5% to 7% of the aluminium bronze plasticity, suitable for cold working use. Aluminium content is greater than 7% to 8%, the strength increases, but the plasticity decreases sharply, so more in the cast state or after hot work. Aluminium bronze wear resistance and corrosion resistance in the atmosphere, seawater, seawater carbonic acid and most organic acids, are higher than brass and tin bronze, aluminium bronze can be manufactured gears, bushings, worm gears and other high-strength wear parts as well as high corrosion-resistant elastic components, the main grade is ZCuAl10Fe3.
