论环保铜合金研究方向（续）

2．2硅磷系环保合金的开发 本系合金开发的目的是在黄铜中加入富有、廉价元素硅、磷等以求产业化生产环保合金。由于铋、碲、锑等属于稀有金属，地壳中的含量极为稀少，如果广泛用于易切削黄铜合金势必造成资源上的不足，对长期发展产生影响。国外早已针对这一问题进行过深入的研究，

Discussion on Research Direction of Environmentally Friendly Copper Alloy

This article summarizes the developing situation of environmentally friendly copper alloy at home and abroad, focusing on developing situation of silicon phosphorus brass, It is considered that this series of alloy is a good low-cost environmentally friendly alloy based on rich element. It has important application prospect in sanitary system and is an important revolution made to lead brass material which has been used for a long period in history.
