NiCr 80/20 Thermal Spray Wire High Purity Nickel Chromium Wire

Thermal Spray Wire

Ni55Cr45 alloy

NiCr 80/20 is a high purity nickel chrome wire specifically designed for arc spraying., 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). The materials show an exothermic reaction during the spray process, also produce coatings with high bond strengths that self-bond to most metallic substrates, NiAl 80/20 can be require minimal surface treatment. Bond strengths in excess of 9000 psi can be obtained on blasting surfaces of gravel. It has good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending.

Supply  Size: 1.2mm /1.6mm /2.0mm /3.2mm or Customized
