Abstract
The invention discloses novel lead-free copper alloy material for welding and a preparation method thereof. The novel lead-free copper alloy material for welding comprises, by weight percent, 13-15% of tin, 0.5-1.5% of manganese, 16-18% of zinc, and the balance of copper. The lead is replaced to meet the requirements of ROHS (restriction of hazardous substances) while the performance of the traditional welding material is guaranteed. Zinc oxidization can be stopped by adding the manganese. The cost of the material is lowered greatly, and further, stability of welding carrier is increased and the service life of the welding carrier is prolonged.
