Brazargent 1520Si
Silver brazing alloy: Ternary alloy – 20% Ag and Si
Product description
Ternary alloy whose main elements are: copper, zinc and 20% silver, with 0.2% Si. The addition of silver and zinc lowers the melting temperature.
This viscous alloy is suitable for brazing the main ferrous and non-ferrous metals, with the notable exceptions of aluminum and magnesium. Thanks to its low fluidity, it is suitable for work where access is restricted, and has good joint-filling capabilities.
Cost-effective, multi-purpose silver-based brazing alloy.
Bare rods in Ø 1.5 – 2 – 2.5 – 3 mm, coated rods in Ø1.5 and 2 mm, standard length 500mm. Also available in wires and preforms.
Product application instructions
Suitable for difficult jobs that cannot be carried out with brazing alloys. Cadmium-free, it can also be used in the food industry. Its structure also enables stepped brazing (reheating).
For use with AgFlux or coated rods (standard color: white), when brazing in the open air.

Why choose this solder?
BRAZARGENT 1520SI is a cadmium-free ternary brazing alloy. Its silver content (20%) enables the liquidus temperature to be lowered
to 810°C. Good fluidity, this alloy is used in particular on assemblies with large clearances
(0.2 mm) or to obtain loaded brazing beads.
Properties of brazed joints: The properties of brazed joints depend on a number of factors, including base metals, joint geometry and
possible interactions between base metals and filler metal.
