High wear-resistant aluminum bronze alloy, sliding member using the alloy

摘要

The present invention provides a wear resistant aluminum bronze alloy for a sliding member in various industrial machines and a sliding member made of the alloy.;The alloy of the present invention comprises 7 to 12% by weight of Al, 1.5 to 5.5% by weight of Mn, 0.45 to 2.7% by weight of Si and the balance of substantially Cu, and Mn-Si compound is dispersed in the alloy structure . The alloy has an elongation of 5% or more.;The alloy of the present invention is twice as abrasion-resistant and abrasion resistance as the conventional aluminum bronze alloy (JIS-ALBC2).
