Alloy C-276 Thermal Spray Wire Hrc 35 Typical Hardness 7000 Psi
Bond Strength
PRODUCT OVERVIEW
Alloy C-276 is a high purity nickel-chrome-moly-tungsten (Alloy
C-276) wire specifically designed for arc spraying. It produces
dense, well-bonded coatings with good resistance to corrosion, and
stress cracking in caustic, acidic and chloride mediums. It’s high
hardness makes it very resistant to abrasion and metal wear.
TYPICAL DEPOSIT CHARACTERISTICS:

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.
