饰品用贵金属合金及其钎焊工艺的发展

Review of precious metal alloys for jewelry and relevant brazing technology

概述了金、银两类贵金属及其钎焊工艺的发展。介绍了各类型饰品用金、银合金种类、特性和应用范围,并针对不同类型的金、银合金所适用的钎焊材料及钎焊工艺。首饰用贵金属合金所使用的钎料种类繁多,国家标准中已规定适用于各行业的银合金钎料(包括含钯钎料)48个牌号,金合金钎料19个牌号,但未进一步对饰品用贵金属钎料进行规定。近年来市场对饰品用贵金属合金的需求逐年增长,对其成分的安全无害标准亦有提升,故饰品用贵金属合金钎料的无害化、系列化和标准化已成为必然趋势,相关研究在制定行业标准、提高国际市场竞争力上具有重要意义。

The topic covers the gold and silver alloys and the brazing technology for precious metal jewelry. Categories,characteristics and applications of gold and silver alloys for jewelry were listed along with the specific brazing filler metal and brazing technology for every type. According to the national standards,48 brands of brazing filler metals for silver alloys( including palladium alloys) and 19 brands of gold alloys were used within varieties of industries,but none for jewelry industry. Along with the growing of market demand for precious metal alloys,material safety standards for brazing filler metals specifically for jewelry are in request. It is certain that nontoxic,series of standardized jewelry industrial brazing filler metals as well as relevant national standards will soon walk on to stage.
