Standard: GB/T 13808-1992
QAl9-4 Characteristics and Scope of Application:
QAl9-4 is an aluminum bronze containing iron, which has high strength and anti friction properties, good corrosion resistance, and good pressure workability under hot conditions. It can be welded and gas welded, but its fiber weldability is poor. QAl9-4 aluminum bronze can be used as a substitute for high tin wear-resistant bronze.
