黄金具有很多优良特性,但因其稀缺且价贵,只能用在一些重要的电子仪表和高级时髦的装饰品上.本文主要研究含有Al、Ni、Cr等合金元素的铜基合金,代替黄金作装饰品,实验表明,这些合金的色泽达到22K金的色泽. 这些合金还具有良好的抗氧化性.抗腐蚀性和耐磨性.良好的可加工性和综合的力学性能.适合制作各种类型的仪表元件和装饰品. Gold has many excellent features, but because of its scarcity and expensive, can only be used in some important electronic instruments and advanced fashion accessories.In this paper, the main study containing Al, Ni, Cr and other alloying elements of copper-based alloys, instead of gold For decorations, experiments show that the color of these alloys to 22K gold color. These alloys also have good oxidation resistance. Corrosion and wear resistance. Good machinability and comprehensive mechanical properties. Suitable for the production of various Type of instrument components and decorations.
