銅錫合金鑄件(錫青銅和火炮金屬鑄件)
Copper-tin-alloy castings (tin bronze and gun metal castings)
歸類 銅及銅合金
標(biāo)簽 砂型鑄造錫青銅
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:dome stones and dome. pieces, spindle nuts moving under load, worms. and screw gears
密度 8.6 g/cm3
