It further provides a process for making silver alloy containing silver in an amount of at least 77 wt % Ag, 1-7.2 wt % Cu copper, at least 0.5 wt % Ge and B together with any further ingredients for said alloy and any impurities, comprising the step of melting together fine silver and a master metal composition which is at least a ternary alloy of copper, germanium and boron, e.g. 92.5-92.8 wt % Ag, 6.0-6.3 wt % Cu, about 1.2 wt % Ge and 1-15 ppm boron as grain refiner. The resulting silver alloy exhibits good tarnish and firestain resistance and can exhibit significant precipitation hardening on gradual air cooling. In a further aspect the invention relates to method for manufacturing a copper-based master alloy for use in the manufacture of silver alloy products, wherein the molten master alloy prior to solidification is treated with a decomposable boron compound e.g. a boron hydride or metal borohydride.

摘要： A method for joining two elements using a silver-based alloy having a germanium content is described. The method comprises providing two elements to be joined together, at least one of the elements comprising a silver/copper/germanium alloy having a silver content of at least 77% by weight, a germanium content of between 0.4 and 7% by weight, typically from about 0.5% to about 3%, the remainder principally being copper apart from any impurities. The alloy also contains boron as a grain refiner at a concentration of greater than 0 parts per million and less than 20 parts per million, more typically less than about 10 parts per million, with working embodiments including boron in an amount of about 2 parts per million. The two elements are placed adjacent one another such that a portion of a free surface of the silver/copper/germanium alloy contacts a portion of a free surface of the other element without interposing a filler material between the two free surfaces. The two free surfaces are heated where the two elements are adjacent one another to a temperature below that of the solidus temperature of any one of the constituent materials of the elements, thereby joining the two elements by a diffusion process. A silver/germanium alloy also is described having a silver content of at least 77% by weight and a germanium content of between 0.4 and 7% by weight, which alloy contains boron as a grain refiner at a concentration of greater than 0 parts per million and less than 20 parts per million.

摘要： A firestain and tarnish-resistant ternary alloy of silver, copper and germanium contains from more than 93.5 wt % to 95.5 wt % Ag, from 0.5 to 3 wt % Ge, optionally 0.5 wt % Zn and the remainder, apart from incidental ingredients (if any), impurities and grain refiner, copper. In order to further protect an article made from the alloy, it may be surface treated with an alkanethiol, alkyl thioglycollate, dialkyl sulphide or dialkyl disulphide. Embodiments of the above alloy exhibit relatively low elution of copper when subjected to a simulated sweat test.
