ZCuSn10Pb1: corrosion resistant, especially to dilute sulfuric acid, hydrochloric acid, and fatty acids. Structural material, corrosion-resistant, acid-resistant fittings as well as crusher bushings, and shaft tiles. ZCuSn10Pb5: lubricating function, good function and corrosion resistance, suitable for use as the bimetallic casting material. Bearings for vehicles, bimetallic shaft tiles for internal combustion engines with peak loads up to 100Mpa, as well as piston pin bushings, friction plates, etc.
ZCuPb10Sn10: high hardness, good performance, not easy to seize the appearance, good casting and cutting function, excellent corrosion resistance in the atmosphere, and fresh water. Can be used for high load (below 20Mpa) and high sliding speed (8m/s) under the operation of parts, such as connecting rods, bushings, shaft tiles, gears, worm gears, etc. ZCuPb15Sn8: In the absence of lubricant and water lubricant conditions, graphite bushings sliding and self-lubricating function are good, easy to cut, casting function is poor, corrosion resistance to dilute sulfuric acid function is good. High external pressure and side pressure bearings, can be used to make copper cooling tubes for cold rolling mills, impact load resistant parts up to 50Mpa, bimetallic shaft tiles for internal combustion engines, piston pin bushings used primarily for larger loads up to 70Mpa, acid resistant accessories.
