    Melting range: 1085 - 1100 °C

    Tensile strength: 301 N/mm2

Welding process

  • Brazing

Description and Applications

  • The alloy is particularly well suited for bridging wide gaps (max. 0.2 mm). Suitable for workpieces made of alloyed and unalloyed steel, wolfram, molybdenum, tantalum and hard metals (e.g. drill bits exposed to high mechanical stress). The contained nickel facilitates the wetting on hard metals.
