Abstract

German silver type alloy contg. Mn comprises by wt. 8-18% Ni, 3-10% Mn, 0.5-2.5% Pb, 38.6-40.6 Zn, balance Cu, in which Zn % + Mn % (1.35-0.07 (Mn %) -0.3 Ni % . The alloy has a microstructure contg. 25.75% beta phase, balance alpha phase. The beta-phase improves hot working, while the addition of the manganese improves the cold working properties.
