Abstract
The invention provides a white noble metal alloy composition. The white noble metal alloy composition is a product which is formed by combining a plurality of value-preserving and circulating noble metals, and which has purely natural shiny white color and high fold-line mirror face effect, and is environment-friendly, resistant to corrosion, high in plasticity, excellent in machinability, high in product additive value and non-comparative. The platinum family is used as major color and luster elements of the white noble metal alloy composition; and the white noble metal alloy composition comprises an alloy composition of at least one of gold and silver and other optional one or more metals different in metallic properties, and a rare metal element; the combination of the components of the white noble metal alloy composition is suitable for a white noble metal formula for manufacturing jewelries and crafts. The synthetic metal complex provided by the invention is especially suitable for manufacturing jewelries with high technical requirements; and no matter in the form of wire, sheet, pipe and metal particles for casting, all the forms of materials can be sufficiently used in reverse-mould casting products of woven chain oil pressure products.
Description
Technical field
The present invention relates to white precious metal alloys composition, more specifically, in a kind of embodiment, the present invention relates to be suitable for to make the white precious metal alloys composition of the relevant finished product made from precious metal with other of jewellery, in addition, the invention still further relates to manufacture method by white precious metal alloys composition.
Background technology
Finance on the world market and rapid economic development, international overall situation politics is basicly stable, and the development of the third world is at a tremendous pace, and the India in the gold brick system and China all become the maximum consumption market of luxury goods in the world in recent years.Many jewellery are made the commercial city and are being removed to develop the precious metal jewelry that has more value energetically, oneself a large amount of employing is based on the pure white ornaments of platinum metals on material, particularly Japan and Chinese market development, every year is all with double-digit growth, and the human consumer to the requirement of ornaments to change, to the metallographic phase ratio of the synthetic composition of the platinum in former market with platinum group, day deep understanding is arranged, many jewellery manufacturers makes jewellery with platinum, because platinum presents better treatment characteristic and lower temperature of fusion than platinum, the platinum jewellery are usually than the easier making of platinum jewellery, these alloy composites generally include gold and at least a additional metal, such as nickel, silver, copper or other metal essence.To can be directed at the color and luster " whiter " of ornaments in the synthetic metal of nickel adding and increase cost hardly, at present in the world the composition of nickel there is certain standard, because the nickel metal not only has the fragility of alloy composite in technology, long-term liver and the cardio-pulmonary function of wearing the infringement people cause serious dermatitis and allergic.
Silver is the whitest metal, but in case be exposed in the air namely can oxidation, the certain restriction of plasticity-tool on technology.
Be known synthesis mode with silver and the composition of nickel adding gold and other metallic element.In this synthetic fraction, because international golden standard composition ratio (composition is by 16.64 – 91%), gold must be main metal, because the intrinsic yellow of gold, therefore synthetic alloy composite color and luster should be pale green or yellowish tone mutually.For goods are reverted to white, must after finishing, product carry out post-treatment, and how with plating mode, the rhodium of platinum metals is plated again/is coated on the goods.
Platinum and/or palladium also be introduced in the platinum.Because high cost uses these elements in platinum, is infeasible at economic angle.
