wisdom Brand Tafa75B for thermal spray wires
Tafa75B is a solid thermal spray wires, It can be use as bond coatings and for machine element restoration widely. The materials show an exothermic reaction during the spray process, Also can produce dense coatings with exceptionally high bond strengths that self-bond to most metallic substrates and can tolerate elevated temperatures and oxidizing atmospheres. Our Nickel Aluminum 95/5 thermal spray wires can equivalent to: Sulzer Metco 8400,75E Nickel Aluminum 95/5.
It is specifically designed for arc spray systems.
