3.17mm Thermal Spray High Heat Wire Nial8020 Gray Color For Tube Undercoat

3.17mm NiAl8020 cord thermal spray wire for tube undercoat not alloy wire

Same grade :TAFA 79B NiAl8020 Thermal Spray wire Metco 405

The wire produces superior bond coats that are dense and resistant to high temperature oxidation, thermal shock and abrasion. The material is equally suitable as a one-coat system;

This wire is manufactured exclusively for wire arc spraying. The unusual self-bonding ability of the alloy is attributed to the exceptionally high temperatures the nickel-aluminum reaches and which on impact with the base material, forms a strong bond. Measured bond strengths have been determined to be 55 percent higher than those formed by exothermic reactions of nickel and aluminum mixtures -- the previous materials available to demonstrate such self-bonding characteristics. One of the major problems in achieving high quality, well bonded coatings in any thermal spray process is the costly, extensive preparation of the substrate. 79B eliminates the problem. The coating, through extensive testing, has also been found to be superior to exothermic materials in sharp edge and impact loading.

79B wire is self-bonding to a broad range of smooth metal surfaces including annealed or hardened carbon
steels, annealed or hardened alloy steels, stainless steels, aluminum, nickel, cast iron, titanium and tantalum. It is not self-bonding to copper based alloys or tungsten.
