Tin bronze

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.
C83600 has high strength, sufficient stability below 300 degrees, suitable for friction parts working under heavy load conditions, low tin bronze containing cast with low cost and good wear resistance, suitable for general bearing. bushings and thin wall castings, etc.
