Product Description

OCr25Al5 Thermal Spray Wire 1.6mm, 2.0mm Iron based alloy for thermal spray

 

PRODUCT OVERVIEW:

OCr25Al5 is an iron chrome aluminum alloy wire specifically designed for arc spraying. It produces dense, well-bonded coatings with excellent wear and high temperature oxidation resistance. It is widely used for machine element repair and dimensional res toration applications. OCr25Al5's low shrink characteristic alloys increased coating thickness. OCr25Al5 is machinable.

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.
