Abstract

The brass-aluminum-manganese-iron alloy, with micro-addition of niobium and as a raw melt product, is particularly, but not exclusively, applicable in the production of valve bodies, bearings and bushings and it comprises, by mass: 14.0 to 18.0% zinc (Zn); 5.0 to 7.5% aluminum (Al); 2.5 to 5.0% manganese (Mn); 2.0 to 4.0% iron (Fe); 0.1 to 0.2% niobium (Nb) and the remainder of copper (Cu). The alloy may optionally contain the following impurities, by mass: maximum 0.2% lead (Pb), maximum 0.2% tin (Sn), maximum 1.0% nickel (Ni) and maximum 0.2% silicon (Si).
