首饰K金补口的性能要求浅析

K金是由金及补口材料构成的金合金，补口性能的优劣直接关系到首饰品的质量。不同厂家生产的补口性能差别很大，需要建立对K金补口的性能评价方法，既有利于对补口生产提供指导，也利于首饰生产企业根据自己的需要作出适当的选择。评价K金补口性能应从物理性能、化学性能、力学性能、加工性能、安全性及经济性等多方面进行，优良的补口应具有性价比高、综合性能好的特点。

Analysis of Requirements for the Performance of Karat Gold Master Alloys for Jewelry

Karat gold is made up of pure gold directly related to the quality of jewelries and master alloy, and the performance of master alloys is Since different master alloys produced by different manufacturers have various performance, it is required to establish performance- evaluation methods, which is not only helpful to provide guidance to the production of master alloys, but also conducive to jewelry manufacturers to make appropriate choices according to their own needs. This paper suggests that the performance evaluation of master alloys should be conducted from the following aspects： physical properties, chemical properties, mechanical properties, processing performance, safety and economical performance. As an excellent master alloy, it should possesses the merits of cost-effective and good integrated performance.
