FIELD: metallurgy.SUBSTANCE: alloy comprises the following components, wt %: from 0.2 to 0.8 Sn, from 0.1 to 0.6 Ni and/or Co, from 0 to 0.05 Zn, from 0 to 0.2 Fe, from 0.008 to 0.05 P, Cu - balance. The invention also relates to a composite material, comprising a base made of the proposed copper-tin alloy and tin layer applied on it. Process and physical properties of the alloy are comparable to properties of the alloy CuFe2P.EFFECT: alloy is easily welded with a laser, and it may be returned back into circulation.12 cl, 1 tbl, 2 dwg |
