Nickel Chrome wire NiCr80/20 for arc spray wire
Nickel Chromium 80/20
Introduction
Nickel Chromium 80/20 wires are products appropriate for general use. The materials show an exothermic reaction during the spray process, Also produce coatings with high bond strengths that self-bond to most metallic substrates, Except the copper and tungsten based materials. It can equivalent to Tafa 06C
Nickel Chromium 80/20 widely used for electrical arc thermal spray application, It can produces dense,Well
bonded coatings with excellent machineability, electrical conductivity and high temperature oxidation resistance up to 1800 degrees F (980 degrees C). Widely applied to repair machine parts, electrical and high temperature corrosion applications.
Typical Uses and Applications
Bond Coatings under ceramic top coatings.
Build-up of machinable carbon steel and corrosion-resistant steels.
Under the condition of high temperature and low temperature as the Fretting resistance.
High-temperature anti-corrosive coating.
