SILVER BRAZING RODS 49% SILVER

Cadmium-free special brazing alloy with high silver content (49%) and outstanding mechanical properties. Nickel and manganese additions give to this alloy excellent mechanical strength and corrosion resistance properties. The alloy will also wet and adhere to difficult to braze materials such as widia, tungsten carbide, cemented carbides, cast iron, etc. Excellent resistance to high service temperatures. Best applications are to be found in the carbide tipped tools sector and in the brazing of diamond segments on drilling tools.

Optimal joint gap: 0,1 - 0,25 mm

This alloy is RoHS compliant (EU Directive 2002/95/EC).

Available as bare rods and coil. This alloy can be supplied in a variety of different make-ups: for more information kindly contact the Customer Service.

Main technical properties:

Composition % (Ag - Cu - Zn - Ni - Mn): 49 - 16 - 23 - 4,5 - 7,5

Melting range SOL - LIQ (°C): 680 - 705

- Density (g/cm3): 8,9
