How AlCoFeCr Alloy Powder Enhances Corrosion Resistance in Harsh Environments

Published by HUAXIAO TECH manufacturer

AlCoFeCr alloy powder is a high-entropy alloy designed for exceptional corrosion resistance and mechanical stability. It is increasingly used in chemical processing, marine, and energy industries where materials face aggressive environments.

Balanced Composition for Strength and Stability

This alloy combines aluminum (Al), cobalt (Co), iron (Fe), and chromium (Cr) to form a stable solid solution with:

• Excellent oxidation and corrosion resistance

• High hardness and wear resistance

• Good thermal stability for elevated temperature applications

Such balanced chemistry improves durability in highly corrosive and high-temperature conditions.

Outstanding Corrosion and Wear Resistance

The high chromium and aluminum content helps develop a protective oxide layer that:

• Prevents pitting and crevice corrosion in chloride-rich environments

• Enhances resistance against oxidation at elevated temperatures

• Reduces material degradation in abrasive and erosive conditions

This makes AlCoFeCr powder suitable for components exposed to seawater, acids, and industrial gases.

Tailored for Additive Manufacturing and Thermal Spray

Produced by advanced atomization techniques, this powder offers:

• Uniform spherical particles ensuring excellent flowability

• Compatibility with laser powder bed fusion (LPBF) and thermal spray coating

• High packing density for dense, defect-free parts

Common Applications

• Marine engine parts and offshore structures
