Silver Brazing Alloys:  

AG103 can be used to join all the common engineering materials (excluding aluminium) such as copper, copper alloys (including, brasses, bronzes, gun metal, nickel silvers, aluminium bronze, copper nickel), steels including, mild, carbon, tool steel, stainless steels, low alloy steel), tungsten carbide and PCD segments. On large or difficult to wet tungsten carbide pieces specialised silver brazing filler metals containing nickel / manganese are often preferred.

Conditions for use: This filler metal is mainly used for brazing in air with a flux. In most cases CMA flux can be used in conjunction with AG 103. However, flux selection is application dependent.

AG 105 is a very widely used cadmium free silver brazing filler metal. It offers a combination of medium melting temperature and flow characteristics. It can be used to fill gaps that cannot be tightly controlled. These properties make it a popular choice as an alternative to the higher silver content filler metals or when changing from medium flow cadmium bearing products such as Cadmium Bearing L-Ag34cd (34% Ag).

It is widely used as a general purpose silver brazing filler metal as well as in joining copper to steel in refrigeration pipe work. It should be noted that this filler metal contains tin and may be described as being 'hot-short'. It should not be quenched from high temperatures (in excess of 300^oC) and care should be taken when it is used to braze components with widely differing coefficients of thermal expansion as in both cases cracking of the joints may occur.
Optimum joint gaps at brazing temperature are 0.075-0.2mm.

Product uses: AG 105 can be used to join most common engineering metals - copper, copper alloys including, brasses, bronzes, gun metal, nickel silver, aluminium bronze, copper nickel, steels including, mild, carbon, tool steel, stainless steels, low alloy steel. This alloy is not normally recommended for brazing tungsten carbide and PCD segments where lower melting or nickel / manganese containing silver brazing filler metals are often preferred.

Conditions for use: This filler metal is mainly used for brazing in air with a flux. In most cases CMA flux can be used in conjunction with AG 105. However, flux selection is application dependent.
