Cadmium free Brazing Alloys

Cadmium free brazing alloys are suitable substitutes for Cadmium bearing alloys. There are no toxic Cadmium fumes but often a higher silver content is required to aid the alloy in its capillary flow. these types of alloys have medium fluidity and wider melting range comparing to Cadmium bearing alloys. Their narrow melting ranges make them ideal for applications where liquation maybe a problem.They are mostly used in food industries and are suitable for joining electrical components requiring high electrical conductivity and are suitable for sea water applications being resistant to dezincification. Chemical and physical characteristics of these alloys are shown in table.
