The silver-base filler bls are a kind of brazing filler bls of silver-base solid solution,with excellent usability,low melting point,good wettability,great strength,good plasticity,contact and corrosion-resisting.They can be used to brazed all ferrous and nonferrous bls ,such as stainless steel,hard alloy etc.At present,they are applied on the fields such as refrigerator,air conditioner,lamps and lantems,instruments and meters,electrical equipments chemical industry and aerospace industry etc.

        In order to decrease melting point and the content of silver,adding copper,zinc,admium,tin,nickel etc elements to them consists of three elements or many elements alloy filler bls.These products can adopt all kinds of brazing bs.Generally speaking,you should make up the brazing flux in order to get good braze but for the vacuum state operation and the shield gas state operation.

      The silver base filler bls include“withcadmium”and“without cadmium”.The silver base filler bls with cadmium have a little toxicity.These products can`t be applied on the brazed joints which are directly connected with food,drinding water.The working place must wind.

       Before brazing,you must b away all dirt on the brazing place and on the surface of b to be brazed such as greasy dirt.oxide,and so on,the best brazed joints space are between 0.03mm to 0.075mm.
