铝A850.5是一种含2.5%硅的铝合金。硅可以改善铸造性能,因为它在边界及薄膜润滑条件下有良好抗咬合性,低摩擦系数及高的耐磨性。它用于重负荷场合,如轧机轴承,特别适合。成分如下:(%)
Aluminum A850.5 is a 2.5% silicon aluminum alloy. Silicon improves castability because of its good seizure resistance, low coefficient of friction and high wear resistance at boundary and film lubrication. It is especially suitable for heavy duty applications such as rolling mill bearings. Ingredients are as follows: (%)
