Silver-Copper-Zinc-Tin Brazing Alloys (High Silver)
Sanhuan silver-copper-zinc-tin brazing alloy (cadmium-free, low-temperature silver-based brazing alloy) incorporates tin (Sn) into the silver-copper-zinc alloy, reducing the melting point and enhancing ductility. It features a low melting point, excellent wettability, and gap-filling capabilities. The brazed joint has a smooth surface and high strength, making it suitable for materials requiring low brazing temperatures. Additionally, it ensures no cadmium vapor contamination during brazing.
