FCW NICARBW-G
Hardfacing cored wire containing 40-60% tungsten carbides (depending on wire diameter)
Product description
– Arc-welding flux-cored wire containing 50-60% tungsten carbides in a special Ni-B-Si matrix
– Optimum balance between ductility and wear resistance thanks to a deposited metal consisting of
tungsten carbides uniformly distributed in a hard, highly tenacious matrix
– Excellent wetting characteristics
– Can be welded with or without shielding gas.

Why choose this cored wire?
- Exceptional resistance to severe abrasion
FCW NICARBW-G deposits a matrix rich in extremely hard boron and tungsten carbides (often > 60 HRC), which protect parts against :
-wear caused by mineral particles,
-intense friction,
-dry or wet surface erosion.
- Nickel base = better adhesion and resistance to thermal shock
Unlike iron-based alloys, nickel-based alloys offer :
-improved thermal expansion (useful on alloy and stainless steels),
-good adhesion on difficult metals (stainless steel, cast iron, etc.),
excellent resistance to in-service cracking and welding.
- Good high-temperature resistance
The deposit remains stable and effective up to ~600-700°C, enabling it to be used in hot areas (e.g. extruder screws, mixers, wear plates, etc.).
- Corrosion and oxidation resistance
Alloying elements such as chromium and boron offer good resistance to oxidation and light chemical corrosion, even in humid or slightly acidic environments.
