Qal 9-4 Copper ball
C61900 Copper ball
CA103 copper ball
CuA18Fe copper ball
2.0930 Copper ball
Qal 9-4 Copper ball C61900 Copper ball CA103 copper ball CuA18Fe copper ball 2.0930 Copper ball is an iron-containing aluminum bronze with high strength and antifriction. Good corrosion resistance, good pressure workability in hot state, welding and gas welding, but poor brazing, QAl9-4 aluminum bronze can be used as a substitute for high tin wear resistant bronze.
