Abstract
High-strength brass alloy having superior wear maintains single-structure β phase and Fe—Cr—Si-based intermetallic compounds dispersed in the β phase. A high-strength brass alloy for sliding member comprises Zn from 17% to 28%, Al from 3% to 10%, Fe from 1% to 4%, Cr from 0.1% to 4%, Si from 0.5% to 3%, mass ratio, and the remnant including Cu and inevitable impurities. The high-strength brass alloy has structure in which the matrix shows single-phase structure of β phase and Fe—Cr—Si-based intermetallic compounds are dispersed in the β phase. The high-strength brass alloy for sliding member has the structure in which the matrix shows single-structure of β phase and hard Fe—Cr—Si-based intermetallic compounds are dispersed in the β phase. Thus the hardness is increased and wear resistance is improved.
