研制了一种新的无Co ,低Be电阻焊电极合金CuNiBeZrCrRe。研究表明该合金具有较高的硬度、导电率、软化温度 ,满足服役条件苛刻的无汞高速焊轮材料的使用要求 ,可广泛应用于要求较高的电阻焊电极材料。并且该合金不含Co ,Be的含量很低 ,因而降低了成本 ,减少了对人体和环境的污染 ,延长了电极的使用寿命 ,因而对于研究开发环保型焊轮材料具有重要意义。

A new CuNiBeZrCrRe electrode alloy with no Co element and low Be element used in CAPL is investigated. The results show that CuNiBeZrCrRe alloy has enough hardness, electric conductivity and high softening temperature to meet the technical requirements of materials of welding. Furthermore, the alloy has no Co element and low Be element, so the purpose of decreasing the price and pollutio n is reached, and service life of the electrode made of CuNiBeZrCrRe alloy is lo nger. So this study contributes to the investigation of environment protection w elding materials.
