Wisdom Cr23Al5&Cr25Al5 wire Used for Arc Spray Coating
Cr23Al5
Cr23Al5 is a ferritic iron-chromium-aluminum alloy (FeCrAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings, resistant to high-temperature oxidation and corrosion.
Application or Properties: Spray wire with excellent bonding strength. Sprayed layers of this material are-resistant to variation in high temperatures and are used as a buffer layer for all other spraying alloys. Hardness, coating macro: approximately HRc 22. Maximum working temperature: approximately 800° C. Layer thickness: approximately 0.1-0.15 mm.
