牌號 GZ-CuSn12德國W-Nr. 2.1052.03舊牌號   GZ-SnBz12對應(yīng)標準 DIN 1705-1981銅錫合金鑄件(錫青銅和火炮金屬鑄件)歸類 銅及銅合金標簽 離心鑄造錫青銅說明 特性：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：Ring and tubular construction parts as well as longitudinal profiles, e.g. Worm wheel rims, cylinder inserts, high-load adjusting and sliding strips密度 8.6 g/cm3GZ-CuSn12 化學(xué)元素成分含量(%)成分FePSNiCuPbZnSnSb其他合計小值----84--11--大值0.20.40.05288.511130.21.2
