Abstract
The present invention relates to a noble metal alloy for ornaments, which is a noble metal ornamental alloy containing at least one noble metal selected from the group consisting of silver, copper and stainless steel, which comprises 14 to 17 parts by weight of copper relative to 15 to 19 parts by weight of silver, 1 to 3 parts by weight.
Description
The present invention relates to a noble metal alloy for ornaments, and more particularly, to a noble metal alloy for ornaments having a decorative function, a unique pink color alloy excellent in gloss and physical properties, and excellent in workability.
Conventionally, the discoloration resistance is known as a typical example of the alloy is gold (Au) -silver (Ag) -Palladium (Pd) alloy. A silver alloy for a wristwatch case described in Japanese Patent Laid-Open Publication No. 53-43620 is known as an alloy excellent in corrosion resistance, whitish, and easy to finish machining such as a die cut.
This is because palladium (Pd), tin (Sn) and zinc (Zn) are added to silver (Ag) or magnesium, Ni) alone or in combination.
It is a fact that the addition of palladium (Pd) in an amount of 10% or more is a prerequisite for any of the two silver alloys in common. This is intended to improve the sulfidation resistance by containing a large amount of palladium (Pd).
Since the conventional silver alloy contains a large amount of palladium (Pd), its price is high and the color tone of the silver alloy is black gray.
And, as the development of various forms of color according to the demand of the consumers due to the development of culture is being carried out, the development of the pink alloy has been one of the subjects of experiment for a long time, both east and west. In order to reproduce these pink colors, various alloying methods have been studied, but there has been a high probability of failing in color, hardness and gloss.
Accordingly, the present invention is based on the discovery that by adding a relatively inexpensive metal without using a large amount of expensive metal such as palladium (Pd), it does not damage the unique color tone and further maintains the pink color semi-permanently, Silver alloys.
The present invention provides a silver alloy which is more beautiful than the conventional silver alloy, keeps the pink color semi-permanently and excellent in gloss and hardness.
The present invention uses stainless steel in place of expensive palladium and gold, thereby lowering the manufacturing cost and providing various ornaments at low cost.
A noble metal alloy for ornaments according to one embodiment of the present invention is a noble metal ornamental alloy containing at least one noble metal selected from the group consisting of copper and stainless steel, wherein 14 to 17 parts by weight of copper, 15 to 19 parts by weight of silver, 1 to 3 parts by weight of stainless steel.
According to one embodiment of the present invention, it is possible to satisfy a variety of consumers' preferences by providing a silver alloy which is more beautiful than the conventional silver alloy, maintains a pale pink color and is superior in gloss and hardness.
According to one embodiment of the present invention, by using stainless steel instead of expensive palladium and gold, there is an effect that a low cost product can be provided to a consumer by lowering the manufacturing cost.
According to an aspect of the present invention, there is provided an alloy including 14 to 17 parts by weight of copper and 1 to 3 parts by weight of stainless steel based on 15 to 19 parts by weight of silver.
According to another aspect of the present invention, there is provided an ornament made by using the silver alloy as described above.
The present invention can reduce the cost of manufacturing jewelry by replacing expensive palladium and gold with stainless steel, and can produce a silver alloy having a pink color that can not be seen in conventional silver alloys, It has the advantage of being.
Hereinafter, the noble metal alloy for ornaments according to the present invention will be described in detail.
First, the copper and stainless steel are rolled into a thin plate and cut into pieces. The reason for rolling and chopping is to prevent a metal having a low melting point from being vaporized by heating when alloying metals of different properties.
Then, finely chopped silver, copper and stainless steel are placed in a graphite crucible or a ceramic crucible, and borax is added while gradually heating to melt naturally into a liquid state and aggregate together. Next, the alloy according to the present invention can be prepared by agitating the silver, copper and stainless steel evenly so as to mix them with a carbon rod, pouring the mixture into a flask, and cooling to room temperature.
Various kinds of ornaments can be manufactured by using the gold alloy manufactured by the above-described method. The kind of the ornaments is not particularly limited, and examples thereof include a necklace string, a necklace medal, a ring, an earring, a braid, a hair pin, and a brooch. The manufacturing method of the ornaments can be manufactured by a method widely known in the technical field to which the present invention belongs, for example, a hand-making technique or a casting technique, and is not particularly limited.
<Examples>
16 parts by weight of copper and 1 part by weight of stainless steel were cut into small portions
Graphite crucible. Next, the silver, copper, and stainless steel were heated until the graphite crucible became liquid while adding service to the graphite crucible.
Next, the silver is stirred with a carbon rod for 1 hour so that the copper and the stainless liquid are evenly mixed, and then the mixture is poured into a flask and cooled to room temperature to prepare a silver alloy having a beautiful pink color in gloss, hardness and color.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. Various modifications and variations are possible in light of the above teachings. Accordingly, it is to be understood that one embodiment of the present invention should be understood only by the appended claims, and all equivalent or equivalent variations thereof are included in the scope of the present invention.
