With high-purity cathode copper and No. 1 tin ingot as the main raw materials, water vapor combined atomization technology is adopted to prepare fully alloyed copper-tin pre-alloy powder. The product has good batch stability, uniform and stable particle size distribution, and low oxygen content. The sintering alloy and sintering temperature range can be adjusted in the production, reducing the loss of low-melting-point metals and improving the utilization of low-melting-point metals, thereby improving the performance of the products.
