Title
(EN) METHOD FOR PREPARING AN ALLOY OF SILVER AND COPPER FOR ARTICLES
(FR) PROCÉDÉ DE PRÉPARATION D'UN ALLIAGE D'ARGENT ET DE CUIVRE POUR ARTICLES
Abstract
(EN)
A method (100) of preparing an alloy of a silver and a copper for articles is disclosed, comprising at step (102) checking purity of a silver raw material and a copper raw material, at step (104), heating the silver of a specified purity of 99.9% pure and the copper of a specified purity of 98.98% to a temperature of a red hot condition, at step (106), quenching the heated silver and the heated copper in a sesame oil, a buttermilk, a sour gruel, a cow urine, and a decoction of dolichos biflorus, at step (108), melting a mixture of the quenched silver and the quenched copper, and at step (110), cooling the molten mixture of the silver, and the copper to form the alloy, wherein at the step (106). At the step (106), the silver gets purified about 99.52% to 99.99% and the copper gets purified about 99.85% to 99.9%..
