Silver based filler metal is a kind of silver or silver based solid solution filler metal, which has excellent process performance, low melting point,good wettability and ability to fill the gap, high strength, good plasticity,good conductivity and corrosion resistance. It can be used to weld all ferrous and non-ferrous metals except aluminum, magnesium and other low melting point metals.
