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.

Abstract translation: 具有优异磨损性的高强度黄铜合金保持分散在β相中的单结构β相和Fe-Cr-Si基金属间化合物。 用于滑动构件的高强度黄铜合金包括17％至28％的Zn，3％至10％的Al，1％至4％的Fe，0.1％至4％的Cr，0.5％至3％的Si， 质量比，残留物包括Cu和不可避免的杂质。 高强度黄铜合金具有其中基体表现出β相的单相结构，Fe-Cr-Si系金属间化合物分散在β相中的结构。 用于滑动构件的高强度黄铜合金具有其中基体显示单相β相的结构，并且硬质Fe-Cr-Si基金属间化合物分散在β相中。 因此，增加了硬度并提高了耐磨性。
