It appears on the market, and growth momentum is swift and violent.Apparent can see, and the consumption idea of people pursues individual character by focusing on being worth turning to
Change, be particular about style, the technique of jewellery, is particular about jewellery and itself individual character, the matching of dress.Karat gold jewellery are since style is modish, color
It is abundant, price is low, diversification, personalization style meet consumer demand, and therefore it is also continued to develop.
Although the research and development of rose gold, industrialization and market sale achieve very beautiful achievement, rose gold is also referred to as in karat gold
Most influential product.However, it is necessary to which mainly arriving rose gold substantially still belongs to billon.Due to having the value preserving of gold
Function, and golden scarcity, rose gold is extremely important product in high-grade field of jewelry.But with people's lives water
Flat raising, and to the loose property of noble metal demand, a kind of surface color having rose gold of market in urgent need and the material
It is also required to have your the natural gas that precious metal alloys have, but price also wants cheap to user can be made largely to adopt simultaneously
With.So far, roseate noble metal only has rose gold, even occurs without roseate silver alloy.Although going out in the market
Rose silver jewellery is showed, but these product itselfs are not real rose silver.Only common silver jewellery, in addition surface is plated
One layer of rose gold is gone up.Since the silver jewellery of rose gold plate is easy to happen discoloration in use, fades and surface is ground
Damage, rose silver available on the market（It is the silver jewellery for plating rose gold in fact）Will fade phenomenon after using some months.
This phenomenon at home and abroad generally existing.
But it must be observed that although China's bullion industry, especially jewelry gold alloy, quickly grow, but due to rising
In step evening, starting point is low, and also there is a big difference compared with world level on some sport technique segments.Industry problems do not solve for a long time,
Not only affect the market sales volume and usage experience of Related product, also it is serious limit such product international scope city
Field occupancy volume.It has been the inevitable problem of field of jewelry to develop simultaneously industrialization to have roseate silver alloy, for a long time
Domestic many research institutions and enterprise have carried out multi-faceted trial, but regrettably, it not yet obtains so far
The progress of any substance.It is not that color is not up to standard, without rosiness possessed by rose gold in the exploitation of existing rose silver
Value is exactly that the roseate silver alloy corrosion resistance of gained is too poor, will occur in the occasion coming months of experiment abrasion or
Person is faded.
By advanced design of material technology can by the thermodynamics and kinetics means of bottom to alloy material into
Row innovation, and prodigious market value is had to the problem solution and industrialization of developing and develop rose silver.In face of swashing increasingly
Strong domestic and international market competition, it is necessary to which paces of accelerating restructuring, this is not only China's jewellery industry survival and development
It needs and the development trend of world today's related field.
