Wisdom Brand FeCrAl Wire Used for Thermal Spray Coating
Introduction
FeCrAl is a high-resistivity iron-chromium-aluminium alloys for use up to 1400º C (2550º F). With the well-bonding coating and high temperature oxidation resistance. So they can use in variety of industry.
They can equivalent to: TAFA Alcro PMET731
Typical Uses and Applications
Applications where good corrosion and oxidation Resistance is required
Applications for wear resistance such as erosion and abrasion
Machine element repair and restoration
Resistance to chloride-ion attack in marine environments
As a replacement for hard chrome plating
Bond coats in high-temperature coating systems
l Protective coatings against sulphur-containing atmospheres
l Protective coatings against scaling of conventional low alloy steels
