Cadmium free silver alloys
Universal cadmium free silver alloys are used for brazing any steels, copper, and copper-based alloys as well as for nickel and nickel-based alloys. Generally, they are used at operating temperature of -200 °C to +200 °C.
These alloys combine the lowest brazing temperatures with short melting ranges. They are very free flowing and produce neat joints with small fillets. They have excellent mechanical properties and are suitable for sea water applications. Their narrow melting ranges make them ideal for applications where liquation may be a problem.
Universal cadmium free silver alloys can also be delivered as flux coated rods, with flux type FH10 (EN 1045).
Silver and copper phosphorus alloys
Phosphorus containing brazing alloys are recommended when joining copper to copper without flux, and with using flux also for joining copper and copper-based materials, such as brass and bronze. They are used at operating temperature of –70 °C to +150 °C.
These alloys are not suitable for joining materials containing nickel or iron. They should not be applied to materials in which the sulphur is present.
They are widely used in plumbing applications and in refrigeration and air conditioning industries, as well as in the electric industry.
