Abstract
The invention discloses a gold-base alloy for jewelry, which is composed of the following components in percentage by weight: 64.8-70.3% of gold, 12.3-14.2% of copper, 6.5-7.4% of nickel, 2.8-3.7% of cobalt, 4.9-5.8% of palladium and 3.2-4.1% of platinum. The alloy is composed of the gold, copper, nickel, cobalt, palladium and platinum, and has the characteristics of low resistance, low abrasion, favorable ductility, favorable discoloration resistance, favorable oxidation resistance and high corrosion resistance.
Description
Technical field
The present invention relates to a kind of alloy, be specifically related to a kind of jewellery gold-base alloy.
Background technology
Gold-base alloy is to add other elementary composition alloys with Jin Weiji, mainly as various functional materialss: auri precision resistance material, Gold Base Electric Contact Materials, auri solder, auri plated material etc.Instantly the gold-base alloy of producing falls behind gradually in application aspect, and along with the constant growth of productivity instantly, the various aspects of performance of palladium-base alloy cannot meet the demand of society instantly equally.
Summary of the invention
The object of the present invention is to provide a kind of resistance little, wear and tear little, ductility good, health discoloration is strong, oxidation-resistance is strong, the jewellery gold-base alloy of good corrosion resistance.
Technical scheme of the present invention is, a kind of jewellery gold-base alloy, described jewellery gold-base alloy is combined by gold, copper, nickel, cobalt, palladium and six kinds of metal ingredients of platinum, in described jewellery gold-base alloy, the shared weight percent of each composition is respectively: described gold accounts for 64.8%-70.3%, described copper accounts for 12.3%-14.2%, and described nickel accounts for 6.5%-7.4%, and described cobalt accounts for 2.8%-3.7%, described palladium accounts for 4.9%-5.8%, and described platinum accounts for 3.2%-4.1%.
In a preferred embodiment of the present invention, in described jewellery gold-base alloy, the shared weight percent of each composition is specially: described gold accounts for 69.7%, and described copper accounts for 12.4%, described nickel accounts for 6.6%, described cobalt accounts for 2.9%, and described palladium accounts for 5.1%, and described platinum accounts for 3.3%.
In a preferred embodiment of the present invention, in described jewellery gold-base alloy, the shared weight percent of each composition is specially: described gold accounts for 65.4%, and described copper accounts for 14.1%, described nickel accounts for 7.3%, described cobalt accounts for 3.6%, and described palladium accounts for 5.7%, and described platinum accounts for 3.9%.
Of the present invention is a kind of jewellery gold-base alloy, is made up of six kinds of metallic elements such as gold, copper, nickel, cobalt, palladium and platinum, have resistance little, wear and tear little, ductility good, health discoloration is strong, oxidation-resistance is strong, the feature of good corrosion resistance.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of jewellery gold-base alloy, described jewellery gold-base alloy is combined by gold, copper, nickel, cobalt, palladium and six kinds of metal ingredients of platinum, in described jewellery gold-base alloy, the shared weight percent of each composition is respectively: described gold accounts for 64.8%-70.3%, described copper accounts for 12.3%-14.2%, described nickel accounts for 6.5%-7.4%, described cobalt accounts for 2.8%-3.7%, and described palladium accounts for 4.9%-5.8%, and described platinum accounts for 3.2%-4.1%.
Further, in described jewellery gold-base alloy, the shared weight percent of each composition is specially: described gold accounts for 69.7%, and described copper accounts for 12.4%, and described nickel accounts for 6.6%, and described cobalt accounts for 2.9%, and described palladium accounts for 5.1%, and described platinum accounts for 3.3%.
Further, in described jewellery gold-base alloy, the shared weight percent of each composition is specially: described gold accounts for 65.4%, and described copper accounts for 14.1%, and described nickel accounts for 7.3%, and described cobalt accounts for 3.6%, and described palladium accounts for 5.7%, and described platinum accounts for 3.9%.
In addition, can be by regulating the Different Weight per-cent of each composition in alloy, the alloy property height obtaining is differed.
Of the present invention is a kind of jewellery gold-base alloy, is made up of six kinds of metallic elements such as gold, copper, nickel, cobalt, palladium and platinum, have resistance little, wear and tear little, ductility good, health discoloration is strong, oxidation-resistance is strong, the feature of good corrosion resistance.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
