FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly to composition of alloys on the basis of copper for manufacturing of watchcases, coins, flatwares, jewelries. For increasing of alloy free-flowing it allows following compound, wt %: beryllium 0.01-0.03; silver 5.5-6.5; zinc 14.0-15.0; gold 0.5-1.0; cerium 0.2-0.3; tungsten 0.2-0.3; copper - the rest. Alloy free-flowing by spiral test is 450 - 470 mm.
