Mixed copper-tin 10 powder and preparing method thereof

A mixed CuSn-10 powder is prepared from the prealloyed powder prepared from Cu powder and Sn powder by prealloying and the additive through proportional mixing. Its advantages are high uniformity, low segregation rate and content of oxygen, and low cost. 本发明一种混合铜锡10粉及其生产方法，由铜粉、锡粉、预合金法生产的铜锡10预合金粉及添加剂混合而成，铜粉和锡粉的比例为9∶1。由于铜粉、锡粉混合物中加入预合金粉，改变了原单纯铜粉和锡粉混合物的物性，使得物料分布更均匀，偏析率低，烧结后胀大尺寸容易控制，同时兼有原混合法粉末含氧量低工艺简单，生产效率高，生产成本低的优点。
