Abstract : This research has studied the properties of dry sliding wear of three groups of copper alloys , Aluminum bronze , Silicon bronze and Admiralty gun bronze . These three groups were prepared by melting and casting in a metallic molds . These wear samples have been examined by using ( Pin - On - Disc ) apparatus under different wear conditions including applied loads and sliding speeds and disc hardness is constant ( 35HRC ) . It was found that the wear rate increased as the applied load increases and the wear behavior was changed from mild wear into transition wear as the applied load is increased . It was found the wear rate decreased as sliding speed increases for all used alloys . The Admiralty gun bronze alloy is considered as the best alloy because of its high resistance to wear .
