The paste has a highviscosity and dries slowly on air. The alloy is particularly well suited for bridging widegaps (max. 0,2mm). Suitable for workpieces made of alloyed and unalloyed steel,wolfram, molybdenum, tantalum and hard metals (e.g. drill bits exposed to highmechanical stress). The contained nickel facilitates the wetting on hard metals.Heat sources:Inert-gas continuousfurnaceExogasInert-gas continuousfurnaceH 2 /N 2Cracked ammoniaatmosphereVacuum furnaceApplication:Manually or automatically with pneumatical or mechanical dispensing units.
