Description
Technical field
The present invention relates to precious metal processing technique field, relate in particular to a kind of au-alloy and preparation method thereof.
Background technology
Au-alloy is as the existing very long history of material of traditional mode of production gold ornament, the au-alloy adopting of common thousand solid gold jewelries is in 99.99% gold, to add 0.09% silver or copper, its gold content is at least more than 99.9%, hardness is generally softer, the about 72.4HV1 of Vickers' hardness GB/T4340.1-1999, the about 68.9HRF of Rockwell hardness GB/T230.1-2004, the about 19.352g/cm3 of density GB/T1423-1996, therefore thousand pure gold products are easily out of shape, and are not suitable for inlaying jewelry; And the color of thousand pure golds is yellow, in the white jewellery inadequate fashion that seems popular today; In addition, thousand pure golds are because gold content is higher, and its preparation cost is also higher.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of au-alloy and preparation method thereof, can improve the hardness of au-alloy, changes the color of au-alloy, and reduces the preparation cost of au-alloy.
For solving the problems of the technologies described above, the object of the invention is to be achieved through the following technical solutions:
The embodiment of the present invention provides a kind of au-alloy, and the component of this au-alloy represents by weight, comprising:
