NICKEL ALUMINIUM (95/5)

Introduction:
NiAl 95/5 is a solid thermal spray wires, It can be used as bond catings and for machine element restoration widely. The materials show an exothermic reaction during the spray process, Also can produce dense coatings with exceptionally high bond strengths that self bond to most metallic substrates and can tolerate elevated temperatures and oxidizing atmospheres.

The nickel alloy coatings produced have a high degree of structural integrity, are dense and can tolerate elevated temperatures and oxidizing atmospheres. In most cases, material selection is dependent on the specific coating environment; however, all of these materials can be use as bond coatings and for machine element restoration.

Our PGI 95/5 thermal spray wires can equivalent to  Metco:SM 8400  Tafa: 75B        MEC :885It is specifically designed for arc spray systems.

Surface Preparation:

NICKEL CHROME (80/20)

Introduction:

PGI 80/20 wire are products appropriate for general use. The materials show an exothermic reaction during  the spray process. Also produce coatings with high bond strength that self bond to most metallic substrate, except the copper and tungsten based materials .

It can equivalent to TAFA 06C. MEC 821

PGI 80/20 is widely used for electrical arc thermal spray application, it can produce dense well bonded coatings with excellent machine ability, electrical conductivity and high temperature oxidation resistance up to 1800 degrees F (980 degreesC) widely applied to repair machine parts. Electrical and high temperature corrosion applications.

PGI 80/20 coatings produced have a high degree of structural integrity, are dense and can tolerate elevated temperatures and oxidizing atmospheres. The addition of chromium , in some cases substantial amount, enhances their high temperature corrosion resistance.
