Ag-Cu alloy brazing filler metal products

Used for welding of ferrous metals and nonferrous metals, such as copper alloy, titanium alloy, stainless steel, hard alloy.

The product is a kind of Ag or Ag based solid solution. It owns performances such as appropriate melting point, excellent moisture absorption, high mechanical intensity, good plasticity and electric conductivity. It is applied to the welding of ferrous metals and nonferrous metals, such as copper alloy, titanium alloy, stainless steel, hard alloy. It is necessary to be used with Ag flux to get a good quality welding joint, except the vacuum welding or shielded arc welding.
