Description
Technical field
The present invention relates to the 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 the material of traditional mode of production gold ornament, the au-alloy that is adopted of common thousand solid gold jewelries be in 99.99% gold, add 0.09% silver or copper, 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 product easy deformation are not suitable for inlaying jewelry.In addition, thousand pure gold colors are yellow, in the white jewellery popular not enough fashion that seems today.
In the prior art, inlay jewelry and adopt 18K gold or platinum material usually, the 18K gold is to add metals such as about silver of about 25%, copper, zinc to make in gold, and the 18K gold is harder than thousand pure golds, but its Gold Content has only 75%.
Summary of the invention
The problem to be solved in the present invention provides a kind of au-alloy and preparation method thereof, can improve the hardness of au-alloy, changes the color of au-alloy.
For solving the problems of the technologies described above, the objective of the invention is to be achieved through the following technical solutions:
The embodiment of the invention provides a kind of au-alloy, and the component of this au-alloy is represented by weight, comprising:
The zinc of the silver of the nickel of platinum of 90 parts gold, 1-10 part or palladium, 1-10 part, 1-10 part and 1-10 part.

Optionally, the au-alloy that provides of the embodiment of the invention comprises that also the weight percent of each component in the au-alloy is: gold accounts for 90%, platinum or palladium account for 1%, nickel accounts for 5%, silver accounts for 1.8%, zinc accounts for 1.2%, all the other are for congratulating Li Shi repaired mouth H-106A or H-106B.
Optionally, the au-alloy that provides of the embodiment of the invention comprises that also the weight percent of each component in the au-alloy is: gold accounts for 90%, platinum or palladium account for 1%, nickel accounts for 6%, silver accounts for 1.8%, zinc accounts for 1.2%.
The embodiment of the invention also provides a kind of preparation method of au-alloy, comprising:
Getting parts by weight is 90 parts gold, platinum or palladium, the nickel of 1-10 part, the silver of 1-10 part and the zinc of 1-10 part of 1-10 part;
With parts by weight is that the nickel of the platinum of 1-10 part or palladium, 1-10 part is put into molten gold pot, and this molten gold pot is heated;
After waiting to put into the whole fusings of metal of molten gold pot, putting into parts by weight in molten gold pot is 90 parts gold, the silver of 1-10 part and the zinc of 1-10 part, molten gold pot is proceeded heating, and yellow gold and silver, the zinc put in molten gold pot all melt, and obtain alloy solution;
Pour the alloy solution in the molten gold pot into graphite cuvette, cool off 20-30 minute at normal temperatures after, put it into again and be cooled to normal temperature in the tank.
Optionally, getting parts by weight is 90 parts gold, platinum or palladium, the nickel of 1-10 part, the silver of 1-10 part and the zinc of 1-10 part of 1-10 part, also comprises:
Getting parts by weight is the he Li Shi repaired mouth H-106A or the H-106B of 1-10 part;
Accordingly, be that the nickel of the platinum of 1-10 part or palladium, 1-10 part is put into molten gold pot with parts by weight, also comprise:
With parts by weight is that the he Li Shi repaired mouth H-106A of 1-10 part or H-106B put into molten gold pot.
Optionally, be that the nickel of the platinum of 1-10 part or palladium, 1-10 part is put into molten gold pot with parts by weight, before this molten gold pot is heated, also comprise:
