Abstract
The object of the present invention is to provide an abrasion resistant aluminum bronze alloy for sliding members of various industrial machines. The abrasion resistant aluminum bronze alloy consists of Al: 7-12%, Mn: 1.5-5.5%, Si: 0.45-2.7%, respectively in weight, and the rest is substantially Cu, wherein metallic compound of Mn and Si is dispersed among said alloy structure, and elongation percentage is at least 5%. The abrasion resistant aluminum bronze alloy is superior to conventional aluminum bronze alloy (JIS-ALBC2) in seizure resistance and abrasion resistance by more than two times.
