Product Details
Product Introduction
Our Brazing Materials are high-quality silver brazing alloys available in AgCu series, AgCuZn, and AgCuP compositions. Manufactured as rings, strips, wires, and preforms, these alloys deliver excellent flow characteristics, strong joint strength, and reliable performance in both vacuum and atmospheric brazing applications. With 3 tons/month capacity, our brazing materials are widely used for low-voltage electrical contact brazing, air conditioning refrigeration parts brazing, vacuum components brazing, and current fuse applications.
