Abstract
The tarnish resistant silver alloy is constituted of silver as a main component and small amounts of copper, zinc and nickel to provide a tarnish resistant silver alloy in which oxidation prevention can be attained by using easily-procurable metals without using any particular metal.
Description
Technical field
The present invention relates to a kind of non-fading silver alloys, this silver alloys can be used for such as silverwares such as ornament, part and tablewares.
Background technology
Traditional non-fading silver alloys accounts for 3.0% to 9.0% indium, weight by weight and accounts for 0.02% to 0.09% aluminium and silver and constitute.
Yet because this non-fading silver alloys comprises aluminium, so it is easy to oxidation.
Summary of the invention
So, the purpose of this invention is to provide a kind of non-fading silver alloys, can prevent this silver alloys oxidation.
Another object of the present invention provides a kind of non-fading silver alloys, and this silver alloys can use the metal that is easy to obtain, and without specialty metal.
Therefore, the invention provides that a kind of non-fading silver alloys comprises that weight accounts for that 1.25% to 1.35% copper, weight account for that 0.35% to 0.45% zinc, weight account for 0.24% to 0.37% nickel and as the silver of remainder.
The present invention should be understood that to contain all or part of the embodiment that comprises above-mentioned purpose, feature and advantage, unless these purposes, feature and advantage are quoted from limiting claim of the present invention, otherwise be should not be construed as the explanation of restriction to these claims.Above-mentioned and other purposes, feature and advantage of the present invention will be able to clear from description with reference to the accompanying drawings, identical designated components identical among the figure.
Yet, should be understood that especially accompanying drawing only is to be used for explaining and illustrative purposes, rather than intention is to define boundary of the present invention.
Description of drawings
Fig. 1 is the key drawing that illustrates according to first embodiment of the invention; And
Fig. 2 is the key drawing that illustrates according to second embodiment of the invention.
Embodiment
Describe the preferred embodiments of the present invention below with reference to accompanying drawings in detail.Can better obtain the understanding of the present invention by reference Fig. 1.
The non-fading silver alloys of Reference numeral 1 sign, this silver alloys can prevent oxidized, and accounts for 1.25% to 1.35% copper 2 (being 1.25% in the present embodiment), weight by weight and account for 0.35% to 0.45% zinc 3 (being 0.35% in the present embodiment), weight and account for 0.24% to 0.37% nickel 4 (being 0.24% in the present embodiment) and constitute as the silver 5 of remainder.
For non-fading silver alloys 1, in atmosphere, utilize graphite furnace 6 fusing, and be cast in the metal die 7 and obtain the silver ingot 8 of predetermined shape as common commercial metallic substance manufacture method with this component.After this, silver ingot 8 as-annealed condition with about 55 degree under the pressure that reduces was roasted 30 minutes, produced non-fading silver alloys 1 then.
Non-fading silver alloys 1 with this component can prevent oxidized, and aspect colour-fast excellence.And it has identical color with the white noble metal that carries out rhodanizing technology.
Now with reference to Fig. 2 another embodiment of the present invention is described.In the accompanying drawing of this embodiment, with the first embodiment components identical by identical designated, and no longer provide more detailed description.
The second embodiment of the present invention is shown in Figure 2, and the non-fading silver alloys 1A that provides a kind of and first embodiment to distinguish to some extent, this silver alloys accounts for 1.35% copper 2, weight by weight and accounts for 0.45% zinc 3, weight and account for 0.37% nickel 4 and constitute as the silver 5 of remainder.Non-fading silver alloys 1A according to second embodiment has and the first embodiment confers similar advantages.
As mentioned above, advantage of the present invention is as follows:
(1) non-fading silver alloy comprises silver and a small amount of copper, zinc and the nickel as main component, Thereby its excellence aspect colour-fast, and anti-oxidation;
(2) as mentioned above, owing to used silver and a small amount of copper, zinc and nickel, can use to be easy to obtain The metal that gets, and do not need precious metal. In addition, can strengthen hardening characteristics by being mixed with copper; Improve glossiness by being mixed with zinc; And be easy to molten and to (put together by being mixed with nickel Together).
For this reason, do not need to electroplate and just improved hardening characteristics and glossiness, and be easy to system Make, low cost of manufacture;
(3) as mentioned above, the invention provides a kind of non-fading silver alloy, comprise weight and account for 1.25% Copper to 1.35%, weight account for 0.35% to 0.45% zinc, weight account for 0.24% to 0.37% nickel, And as the silver of remainder, have and top (1) and (a 2) identical effect, and can make Produce weight and account for 98% high-purity silver alloy.
Claims (1)
1. non-fading silver alloys comprises that weight accounts for that 1.25% to 1.35% copper, weight account for that 0.35% to 0.45% zinc, weight account for 0.24% to 0.37% nickel and as the silver of remainder.
