NiAl95/5 Thermal Spray Wire
Ni-Al Arc Spray wire for bond coats and one-step restoration, with confirmed composition data including about 93% Ni.
Published coating bond strength of 10,000 psi
The deposited layer can be machined or ground
Published Arc Spray settings and surface-preparation guidance
Product description
NiAl95/5 is a nickel-aluminium thermal spray wire published by Ohmalloy for bond coats and dimensional restoration. Its table reports about 93% Ni, 4.0-5.5% Al and 1.7% maximum total other elements. The deposit may be machined or ground to restore the working dimension.
Surface preparation includes white-metal cleaning followed by roughening with 24-mesh aluminium oxide, rough grinding or machining. Arc Spray settings are 50-60 psi air pressure, 29-30 V, 100-200 A and a 3-6 inch spray distance. CQ can confirm bond strength, deposit rate, efficiency and coverage for the preparation conditions of each application.
Used as a bond coat beneath functional topcoats or as a one-step Ni-Al deposit for general dimensional restoration; the sprayed layer can be machined or ground to its working dimension.
