NiAl Thermal Spray Wire 201.6mm 10 lbs / hr / 100A Deposit Rate Anti - Oxidation
PRODUCT OVERVIEW
NiAl20 is a cored wire specifically designed for either arc spraying or flame spraying. It is self-bonding to most materials and requires minimal surface spreparation. Bond strengths in excess of 9000 psi can be achieved on grit blasted surfaces. NiAl20 exhibits good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending. NiAl20 can be machined and ground to a finish of 5 micro inches.
