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.It is suitable for brazing copper and copper alloy, kinds of steeling parts, Bondi steel pipe with copper pipe, etc.

Advantages
1. Wide range of applications
0%-20% silver content:brazing copper parts. Higher silver content also stainless steel-steels
2. High Joint Strength, No Deformation
Increase silver content can improve strength,lower melting point to protect the base metal
3. Good electrical conductivity
high joint strength, good plasticity, and good electrical conductivity
