摘要
介绍3种主要用于制造船用螺旋桨的铜合金材料,并对其化学成分、力学及其他相关性能进行比较。结果表明两种铝青铜合金的综合性能均优于高强度黄铜合金,为不同水域工作、不同类型、不同级别的船舶应选择何种铜合金材料制造螺旋桨提供参考。
Three commonly used copper alloys for marine propeller manufacture are introduced,and their chemical composition,mechanical properties and other related performance are compared.The results show that two kinds of aluminum bronze have better comprehensive properties than high strength brass.The study provides a reference for choosing copper alloys for marine propeller manufacture.
