Abstract

A Mn-Si-Co-Fe-based high-strength brass alloy comprises, on the weight basis, 15 to 25% of Zn, 1.0 to 5.0% of Mn, 0.3 to 2.0% of Si, 0.01 to 0.5% of Fe, 0.01 to 2.0% of Co, 0.2 to 1.0% of Sn, 5 to 10% of Pb and the balance being Cu and inevitable impurities. The alloy has a novel intermetallic compound [Mn,Si,Co,Fe] substantially in the form of spheroids and has also fine grains. The alloy is adapted for use as sliding members or parts and has very good resistances to wear and corrosion, anti-seizing property and durability.
