Oxidation Heat Resistant Coatings Alloy 625 Wire Hrb 92 Typical Hardness

RODUCT OVERVIEW

Alloy 625 is a high purity nickel chrome wire specifically designed for arc spraying. It produces dense, well-bonded coatings with resistance to corrosion, and stress cracking in caustic mediums.

TYPICAL DEPOSIT CHARACTERISTICS:

Þ Typical Hardness: HRB 92

Þ Bond Strength: 7000 psi

Þ Deposit Rate: 11 lbs/hr/100A

Þ Deposit Efficiency 70%

Þ Wire Coverage: 0.8 oz/ft² / mil

Þ Surface Texture * Variable

* Depends on air pressure used

SURFACE PREPARATION

Surface should be clean, white metal, with no oxides (rust), dirt, grease, or oil on the surface to be coated. Note: It is best not to handle surfaces after cleaning.

Recommended method of preparation is to grit blast with 24 mesh aluminum oxide, rough grind, or rough machine in a lathe.

APPLICATION

Þ Oxidation and heat resistant coatings
