Main features and examples for application of cast alloy (GB1176-87)

Serial number	Trademark of alloy	Main features	Examples for application
1	ZCuSn3Zn8Pb6Ni1	better wear resistance, easy to machining, good casting properties, anticorrosion work under flow seawater	parts working in liquid fuel, seawater, freshwater and steam（225℃）, valves and pipe fittings with pressure not more than 2.5Mpa
2	ZCuSn3Zn11Pb1	good casting property; easy to machining; anticorrosion	pipe fittings working in seawater, freshwater and steam with pressure not more than 2.5Mpa
3	ZcuSn5Pb5Zn5	good properties of wear resistance and anticorrosion; easy to machining; good properties of casting and air impermeability	wear-resistant, anticorrosion parts working in higher load, middle sliding speed, such as axle bush, liner, cylinder cover, piston clutch, pump and worm wheel, etc
4	ZcuSn10Pb1	high hardness, good wear resistance; better casting, cutting and machining properties; good anticorrosion in atmosphere and freshwater	wear-resistant parts working in high load (below 20Mpa) and at high sliding speed (8m/s), such as link lever, bushing, axle bush, gear and worm wheel, etc
5	ZcuSn10Pb5	anticorrosion, particularly to dilute sulphuric acid, chlorhydric acid and fatty acid	structure material, anticorrosive, acid-resistant fittings and crusher bushing, axle bush
6	ZcuSn10Zn2	anticorrosion, wear resistance, good cutting and machining properties, good casting property, higher compactness, good air impermeability	important pipe fittings working in middle and higher load at sliding speed, and valve, faucet, pump body, gear, impeller and worm wheel, etc
7	ZcuPb10Sn10	good properties of lubricating, wear resistance and anticorrosion, adapted for bimetal casting material	bearing for vehicle, internal-combustion engine with peak value over 100Mpa, bimetal axle bush, piston pin and wearing plate, etc
8	ZcuPb15Sn8	In the condition of being lack of lubricant and adopting water lubricant, it has good gliding and self-lubricating properties, is easy to cut; has bad casting property, and has good anticorrosion to dilute sulfuric acid	bearing that has high surface pressure and has side pressure; make copper cooling pipe for cold roller; parts with impact resistance over 50Mpa; bimetal axle bush for internal-combustion engine; mostly use for piston pin with load over 70Mpa, and acid-resistant fittings
