Copper alloy is produced by the following method. (a) Fuse electric copper with 99.9% purity at 900deg.C and add 5% of potassium cyanide to eliminate the floated blue rust and mix pure electric copper 83%, 6% nickel, 7% titanium and 1% tin at the certain ratio, heat it up at 1400deg.C for 30 minutes so as to mix the mixed and fused aqueous alloy fusion. (b) Burn 100% arsenic at 800deg.C to obtain high concentric pure solid arsenic, 3% of which is injected in alloying and the remained impurities are eliminated by mixing and dissolving 1% sodium chloride.
