FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and is to be used for fabrication of watchcases, coins, flatware, jewellery. To upgrade castability the alloy has the composition as follows, wt %: beryllium 0.2-0.3; silver 30.0-35.0; zinc 2.0-3.0; gold 2.0-3.0; aluminium 0.1-0.15; indium 0.1-0.15; tin 2.0-3.0; copper - the rest. The alloy fluidity on the basis of helical sample is equal to approximately 450 mm.
EFFECT: enhanced fluidity of the alloy.
