Abstract
The invention provides gold alloy and a preparation method thereof. The gold alloy comprises the following components in parts by weight: 90 parts of gold, 1-10 parts of platinum or palladium, 1-10 parts of silver, 1-10 parts of pure copper or bronze and 1-10 parts of zinc. The Rockwell hardness GB/T230.1-2009 of the gold alloy is about 60.88 HRB, the Vickers hardness GB/T4340.1-2009 is about 184.15HV1, and the density GB/T1423-1996 is about 17.184g/cm<3>, thus the hardness of the gold alloy is higher than that of the thousand pure gold, and the hardness of the gold alloy is improved.
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/T230.1-2009; 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, and color is relatively more dull.
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 red metal of the silver of platinum of 90 parts gold, 1-10 part or palladium, 1-10 part, 1-10 part or bronze and 1-10 part.
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 silver of 1-10 part, the red metal of 1-10 part or the zinc of bronze and 1-10 part of 1-10 part;
With parts by weight is that the platinum of 1-10 part or palladium are 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, the red metal of 1-10 or the zinc of bronze and 1-10 part, molten gold pot is proceeded heating, yellow gold and silver, red metal or bronze, 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.
The content of gold reaches 90% in the au-alloy that the embodiment of the invention provides, and is higher than the Gold Content of 18K gold 75%, has therefore improved Gold Content with respect to the 18K gold; Change the natural colored effect because the platinum after the high temperature melting or palladium, red metal or bronze, silver, zinc play gold solution, make the au-alloy of making be rendered as rose-red or green lake, therefore abundanter with respect to thousand pure gold colors; In addition, after testing, the about 60.88HRB of au-alloy Rockwell hardness GB/T230.1-2009 that the embodiment of the invention provides, the about 184.15HV1 of Vickers' hardness GB/T4340.1-2009, the about 17.184g/cm3 of density GB/T1423-1996, as seen hardness is higher than the hardness of thousand pure golds, thereby has improved the hardness of au-alloy.
