The tribological behaviors were investigated in a new high strength and wear resistant aluminum bronze, with its friction coefficient and wear-rate lower than those of ZQAl9-4 and ZQAl10-4-4 alloys in terms of Chinese national standard.The results showed that different tribological behaviors were attributed material itself. Under boundary lubrication condition, major wear mechanisms of aluminum bronze are adhesive wear and attrition wear. Its wearability depends mainly on material microstructure, shedding hard-particles, rakes and small pits that can store lubricant. The new aluminum bronze may find wide application in high sliding speed, heavy load and boundary lubrication condition.
