Ferrum based alloy wire OCr25Al5 Thermal Spray Wire 1.6mm, 2.0mm
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.
