Technical field

The present invention relates to technical field of alloy, specifically, being related to a kind of imitative billon.

Background technique

The mankind have found and have thousands of years using the history of gold, longer than the literature record of the mankind.Gold is in no text It just associates with the mankind before word, this is confirmed by more and more unearthed relics.Proof gold jewellery are always that people generally like , this is because proof gold has pure, acid-fast alkali-proof, constant feature, and the magnitude of value is maximum, can fully demonstrate owner The moral character such as plentiful, luxurious, steady, loyal.But when using proof gold as ornaments, since it wears no resistance, it is often worn Surface is easily abraded and portrays, and causes gold to be lost and influences jewellery finish.For this purpose, by adding other elements in proof gold such as Billon is made in Ag, Cu, Ni, Pd, Zn etc., and the intensity of billon, wearability can be improved and adjust billon tone.I.e. So-called karat gold is made to replace proof gold.For many years, gold is mainly used as ornaments in western countries' gold, and oriental countries are then golden main As valuables deposit.But with the improvement of living standards, aesthetic and consumption idea update, the karat gold product in youth group By favor.

Gold serves many purposes in national economy, but price of gold valuableness and resource scarcity.In decoration material field, Countries in the world just strive to find its substitute material from different perspectives.People often will replace gold material, referred to as it is artificial gold or Imitation gold copper-base alloy.Imitation gold copper-base alloy be free from gold but with gold color multicomponent alloy, usually have with 18K fitting it is similar quite Color, good anti-tarnishing ability, casting, processing and polishing performance.It is people institute for Jewelry Accessories and artistic article depth Like.In recent years, Gold production is splendid with its, magnificent pleasing feature becomes fashionable Inter colour, so that state The development and production of inside and outside imitation gold copper-base alloy rapidly develop, and product involves indoor dress sulphur, the architectural hardware, technique of important building Product and tourist souvenir etc..With the development of China's economic situation, the gradually improvement and continuous improvement of people's lives, to imitative gold The requirement of product, will be potential new application prospect.

Color Fashion Trend makes rapid progress in recent years, and the urban woman liked to be beautiful constantly pursues the diversity of jewellery color.Face The diversified imitative gold ornaments of color and ornament materials can undoubtedly meet urban woman to the diversified demand of jewellery color.It is of new generation color What imitation gold copper-base alloy was walked is fashion route, and not only color has differentiated advantages, but also designs and be filled with more fashionable elements, more It can show individual character, embody grade.In addition, colored imitation gold copper-base alloy is elaborated by tens of procedures, under normal wear condition It should be unable to change colour, property is stablized.But regrettably, currently on the market the imitative golden material of the yellow for having gold color Material, the requirement of jewellery and ornament materials is not fully achieved.Make preparing jewellery and ornament materials using such material After 6 months, the phenomenon that being all different degrees of surface corrosion occur, fade and decolourize.It is serious to have influenced such product Industrialization and market occupancy volume popularization.

Although absolute number of China's jewellery industry in quantity and yield is larger, scope of the enterprise is small, core competitiveness It is not strong.In development process, jewelry enterprise is not innovated during productive accumulation, formation is come from usually as processor Oneself characteristic.For a long time, most domestic jewelry enterprise all rest on order processing OEM form, using oneself Production line produces the product of oneself, finally but sticks other people brand.Even some biggish enterprises, first jewelry alloy The critical material of production but almost relies on import, is almost blank out in terms of Novel decoration material development.Therefore, it grinds It sends out and industrialization high-performance jewellery with independent intellectual property rights and ornament materials colored imitation gold copper-base alloy and related technology of preparing Competitiveness for enhancing China's related industry will have the function of very positive.
