被认为是“标准”型轴承材料的铅锡青铜。该合金具有优异的加工性能，良好的硬度，强度和耐磨性，优良的抗磨性。典型应用包括轴承，垫圈，衬套，汽车配件，主轴轴承，机床轴承，起重机轴承，耳轴轴承，辊颈轴承，轧机轴承，燃油泵衬套，水泵轴套，柴油机活塞销衬套，锻压肘节杆轴承，填料箱液压机，液压机主衬里，泵叶轮，通用衬套，管件，泵装置，外球面轴承，等等。
高速、轻型应用，包括垫圈、衬套、轴承、配件、泵叶轮和固定装置。
Material with good wear resistance; corrosion and sea water resistant. The materials G-CuSn12Ni and GCuSn12Pb were developed from this alloy, which are characterized by increased strength and wear resistance and improved emergency running properties. See G-CuSn12 properties, but more uniform, 0.2 limit, higher tensile strength and hardness
用途：dome stones and dome. pieces, spindle nuts moving under load, worms. and screw gears
