NiAl 80/20



NiAl 80/20 is a cored wire specifically designed for either arc spraying or flame spraying. It is self-bonding to most materials and requires minimal surface preparation. Bond strengths in excess of 9000 psi can be achieved on grit blasted surfaces. NiAl80/20 exhibits good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending. NiAl80/20 can be machined and ground to a finish of 5 micro inches.

Arc Spray

Arc spraying is the use of electric arc burning in two consecutive fed between the wires to melt the metal, with a high velocity gas stream molten metal atomization, and the atomization of the sprayed metal particles so that they accelerate the work to form a coating technology .

Flame Spray

The use of a flame as the heat source, the metal and non-heated to a molten state, forming a mist flow in the state of high-speed air jet to the substrate, the injection of the molten minute particles impact upon the substrate above, plastic deformation, into a sheet shape superimposed sedimentary layers.
