High-Quality Chromium Aluminum Alloy CrAl Powder for Industrial Use

CrAl alloys are high-performance oxidation-resistant materials combining chromium's corrosion resistance with aluminum's protective oxide formation. These alloys exhibit exceptional high-temperature stability (up to 1400°C), making them ideal for aerospace coatings, industrial heating elements, and corrosive environment applications.

Ultra-Stable Oxide Layer:
Forms continuous Al₂O₃/Cr₂O₃ protective scale;
Phase-Engineered Performance:
B2-ordered structure (CrAl) for high strength;
α-Cr + γ-Al dual phase for toughness;
Manufacturing Flexibility:
Arc melting, powder metallurgy, and thermal spray compatible;
Machinable in annealed condition;
