The surface of the treated product material is smooth and non-oxidized, and can effectively improve the performance of the product material; and the above-mentioned silver copper strip has the advantages of high strength, good corrosion resistance, high brazing strength and low production cost. It is an important brazing material for brazing connection in large generators.
