MEC 885, Ni 5Al, for Thermal Spray Wire which                           is used in Arc and Coating

NiAl 95/5: Thermal Spray Wire (Sp 95/5, SD 95/5, Ni95Al5) 

NiAl 95/5 is an austenitic nickel-aluminium alloy (NiAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings.

Typical applications for NiAl95/5 are bond coats, as protective coatings against high-temperature oxidation, protective coatings against scaling of conventional iron base alloys and as build-up coatings for dimensional restoration.
