Ag20FC is a general purpose, cadmium-free, silver brazing alloy, with high melting point and very wide melting range. It can be used to join ferrous, non ferrous and dissimilar metals and alloys, such as steel, copper, copper alloys. Due to its very wide melting range this alloy is mostly used for brazing large and/or not uniform joints. Brazing procedures range from manual to induction techniques.
When brazing in an oxidizing environment a proper flux should be used. Tensile strength of joints brazed with Ag20 will generally exceed base metals strength. Joint strength is however a function of various factors, such as: type of base metals to be joined, type of joint, joint clearance, brazing procedure, etc.
