Wires for thermal spray
Composite spray wire for bond coatings equivalent to Metcoloy 405
SP 80/20 NiAl is widely used as a bond coat for subsequent thermal spray layers and as a one step build up material for dimensional restoration of aircraft engines.
SP 80/20 NiAl is a cored wire specifically designed for both, arc spraying and flame spraying. It is selfbonding to most materials and requires minimal surface preparation. Bond strengths in excess of 9000 psi can be achieved on grit blasted surfaces. SP 80/20 NiAl exhibits good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending. SP 80/20 NiAl can be machined and ground to a finish of 5 micro inches.
