C83600 characteristics: although the strength is lower than aluminum bronze (e.g., C95400) and high strength brass, it is superior to other copper alloys in wear resistance and friction reduction. Cast tin bronze surface can form dense SnO2 film, which has good protective effect, so in pump, valve water supply and drain line and ship. Ship equipment has a wide range of uses. |
