Abstract
The invention discloses a precious metal alloy with high stability. The precious metal alloy comprises the following six metal components by weight percent: 86.7% to 91.2% of copper, 4.7% to 5.6% of silver, 1.4% to 2.3% of gold, 0.6% to 1.5% of osmium, 1.8% to 2.7% of platinum and 0.3% to 1.2% of rhodium. The precious metal alloy composed of the six metal components, i.e., copper, silver, gold, osmium, platinum and rhodium, has the advantages of high thermodynamic stability, good corrosion resistance, good physical property, high reliability, good quality, long service life and wide application range.
Description
Technical field
The present invention relates to a kind of alloy, be specifically related to a kind of high stability precious metal alloys.
Background technology
Precious metal alloys be a kind of metal of take in precious metal as basis, add other elementary composition alloys.Precious metal alloys have the main characteristic of precious metal.Precious metal alloys are nearly all used as functional materials.Along with the constant growth of productivity, the user demand of industrial alloy improves constantly, and existing alloy cannot meet the user demand in market gradually.
Summary of the invention
The object of the present invention is to provide the high stability precious metal alloys that a kind of thermodynamic stability is high, solidity to corrosion good, physical property is good, reliability is high, quality is good, the life-span is long, applied widely.
Technical scheme of the present invention is, a kind of high stability precious metal alloys, described high stability precious metal alloys are combined by copper, silver, gold, osmium, platinum and six kinds of metal ingredients of rhodium, in described high stability precious metal alloys, the shared weight percent of each composition is respectively: described copper accounts for 86.7%-91.2%, described silver accounts for 4.7%-5.6%, and described gold accounts for 1.4%-2.3%, and described osmium accounts for 0.6%-1.5%, described platinum accounts for 1.8%-2.7%, and described rhodium accounts for 0.3%-1.2%.
In a preferred embodiment of the present invention, in described high stability precious metal alloys, the shared weight percent of each composition is specially: described copper accounts for 90.7%, and described silver accounts for 4.8%, described gold accounts for 1.5%, described osmium accounts for 0.7%, and described platinum accounts for 1.9%, and described rhodium accounts for 0.4%.
In a preferred embodiment of the present invention, in described high stability precious metal alloys, the shared weight percent of each composition is specially: described copper accounts for 87.2%, and described silver accounts for 5.5%, described gold accounts for 2.2%, described osmium accounts for 1.4%, and described platinum accounts for 2.6%, and described rhodium accounts for 1.1%.
Of the present invention is a kind of high stability precious metal alloys, by six kinds of precious metal elements such as copper, silver, gold, osmium, platinum and rhodiums, formed, have the advantages that thermodynamic stability is high, solidity to corrosion good, physical property is good, reliability is high, quality is good, the life-span is long, applied widely.
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 high stability precious metal alloys, described high stability precious metal alloys are combined by copper, silver, gold, osmium, platinum and six kinds of metal ingredients of rhodium, in described high stability precious metal alloys, the shared weight percent of each composition is respectively: described copper accounts for 86.7%-91.2%, described silver accounts for 4.7%-5.6%, described gold accounts for 1.4%-2.3%, described osmium accounts for 0.6%-1.5%, and described platinum accounts for 1.8%-2.7%, and described rhodium accounts for 0.3%-1.2%.
Further, in described high stability precious metal alloys, the shared weight percent of each composition is specially: described copper accounts for 90.7%, and described silver accounts for 4.8%, and described gold accounts for 1.5%, and described osmium accounts for 0.7%, and described platinum accounts for 1.9%, and described rhodium accounts for 0.4%.
Further, in described high stability precious metal alloys, the shared weight percent of each composition is specially: described copper accounts for 87.2%, and described silver accounts for 5.5%, and described gold accounts for 2.2%, and described osmium accounts for 1.4%, and described platinum accounts for 2.6%, and described rhodium accounts for 1.1%.
In addition, can, by regulating the Different Weight per-cent of each composition in alloy, the alloy property obtaining just be differed.
Of the present invention is a kind of high stability precious metal alloys, by six kinds of precious metal elements such as copper, silver, gold, osmium, platinum and rhodiums, formed, have the advantages that thermodynamic stability is high, solidity to corrosion good, physical property is good, reliability is high, quality is good, the life-span is long, applied widely.
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.
