Description
NiAl95/5 exhibits good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending. It can be machined and ground to a finish of 5 micro inches. It is a self-bonding, one step material and is also suitable for the build-up and dimensional restoration of nickel-based alloys. NiAl95/5 is widely used as a bond coat for subsequent thermal spray topcoats and as a one step build up material for dimensional restoration of aircraft engines.
