Is a flux cored electrode for gas shielded arc welding, but can also be welded by the OA process. It consists of a nickel sheath filled with tungsten fused carbide (W2CWC) and a combination of elements (C, Si, B) to build a special nickel- base alloy. Due to the chemical composition and the chosen grain distribution of the carbides, the cladding is extremely resistant to corrosive and abrasive stress. Both ferritic and austenitic steels (with appropriate heat treatment) can be plated. Thaloy® WSC-DUR Ni has excellent welding properties and excellent flow characteristics. The applied coating is non-porous and features a smooth, clean surface.
NiBSi matrix with intercalated tungsten carbides (52 - 68%)
The hardness grade is 54 - 56 HRc (tungsten carbides approx 2400 HV 0.4).
