How AlCrFeNiCu Alloy Powder Delivers Versatility in Wear-Resistant and Corrosive Environments

As industries demand multi-functional materials for aggressive service conditions, high-entropy alloys (HEAs) like AlCrFeNiCu are gaining prominence. AlCrFeNiCu alloy powder offers excellent strength, wear resistance, and corrosion stability across a wide temperature range, making it a flexible material for both structural and functional applications.

High-Entropy Design for Performance Balance

AlCrFeNiCu is a typical equiatomic HEA, consisting of aluminum, chromium, iron, nickel, and copper. Its unique design enables:

• Solid solution strengthening due to atomic size mismatch

• Uniform microstructure with face-centered cubic (FCC) and body-centered cubic (BCC) phases

• Enhanced thermal stability and hardness

This makes it ideal for use in both ambient and elevated temperature conditions.

Corrosion and Wear Resistance

The Cr and Ni elements form a stable passive film, while Al and Cu contribute to:

• High resistance to chloride-induced corrosion

• Surface hardness for sliding and abrasive wear protection

• Long service life in marine, chemical, and high-friction environments
