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.
