Silver Brazing Alloys

Brazing is a metal joining process whereby two or more metal objects are joined by melting and flowing a filler metal (brazing alloy) into the join.  The brazing alloy must be of a lower melting point than the two metals being joined.

Cadmium Free Alloys

Cadmium free alloys have been developed to be used where the presence of cadmium is unacceptable. For example, the food and beverage industries and laboratory and medical equipment. These alloys are suitable for use on most ferrous and non ferrous metals but due to the capillary flow being less than the cadmium bearing alloys - quite often a higher silver content is required to assist the capillary flow.

Cadmium Bearing Alloys

Cadmium bearing alloys offer an excellent combination of melting range, capillary flow and mechanical properties. These cadmium bearing alloys would be recommended for use as the most economical alloys where the presence of cadmium is acceptable. They should only be used in well ventilated areas and in accordance with information supplied with the product.

Phosphoros Alloys

These alloys are recommended for fluxless brazing of copper and are used extensively in the plumbing, air conditioning and refrigeration industries. As the silver content increases, so does the resistance to vibration, temperature change and stress. These alloys can also be used on brass and bronze with the application of soldering flux.
