Bearing bronze SAE660 (C93200) The difference between tin bronze and high strength brass
ZCuSn5Pb5Zn5 and high force brass ZCuZn25Al16Fe3Mn3 performance difference
ZCuSn5Pb5Zn5 is a casting copper alloy with good wear resistance and corrosion resistance.
Good abrasion and corrosion resistance
Material name: casting copper alloy (5-5-5 tin bronze, sand metal)
Features and scope of application:
ZCuSn5Pb5Zn5 cast copper alloy has good wear resistance and corrosion resistance, is easy to process, and has good casting performance and air tightness.ZCuSn5Pb5Zn5 casting copper alloy is used for wear and corrosion resistant parts, such as bearing bush, liner, cylinder liner, piston clutch, pump cap and worm gear, working at high load and medium sliding speed.

Low heat treatment specification: heating temperature of 1188 ~ 1220 ℃;The pouring temperature of 1150 ~ 1200 ℃.
Sand mold casting, metal mold casting
The difference between high strength brass and tin bronze is that high strength brass has a higher hardness than tin bronze and has a better bearing capacity than tin bronze, but is not as durable as tin bronze.The market price of tin bronze is 30% higher than that of gallic brass.
