 Introduction

The microstructure of silver brazing is silver or silver-based solid solution alloy. It is kind of high silver solder, it has perfect processing property, low melting point, good wettability and good ability to fill the gap, high joint strength, good plasticity, and good electrical conductivity and corrosion resistance. It can be used for brazing all ferrous and non-ferrous metals except aluminum, magnesium, and low melting point metal.And suitable for brazing copper with copper alloy pipe fitting, tools, electrical motor, electrical appliance parts.
