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
