Product description
Flexible rod for hardfacing by oxy-gas welding. Consist of a small diameter pure nickel core wire thickly coated tungsten carbides in a Ni-Cr-B-Si matrix. The weld metal is a heterogeneous metal composed of tungsten carbides (W2C,WC) distributed in a hard and tough matrix. Shows extremely high abrasion resistance. It has got a quiet melting and good wetting. Especially used for hardfacing of mixers, crushing mills, die blades and heads, sand foundary equipment, drilling tricones.
