Coin copper alloy casting and manufacturing method

The present invention relates to a method for producing a highly conductive copper alloy material and a highly conductive copper alloy material which is copper and whose main components include zinc, antimony, tellurium, titanium, cobalt, tin, zirconium, phosphorus, iron, Of the copper alloy material is from 5% to 8%, 0.25% to 0.39%, Zinc, Sb, Te, Ti 0.2% 0.3% 0.1% 0.14% 0.08% ~, 0.15%, 0.05% to 0.15% Zirconium 0.01% to 0.05%, phosphorus 0.07% to 0.15% and iron 0.8% to 1.6%. (2) mixing the melt to prepare zinc, antimony, tin, tellurium, titanium, cobalt, zirconium, phosphorus and iron and the like; and (2) mixing the melt to prepare the copper alloy material with high electrical conductivity, the method comprising the following steps of: 3) a step (2) of melt-mixing molten copper; (4) a solid solution of the mixed solution of step (3), a copper alloy obtained; and (5) an aging treatment of the copper alloy.
