Why CuAl10 Alloy Powder Is Ideal for Marine and Industrial Applications

Published by HUAXIAO TECH manufacturer

CuAl10 alloy powder, a high-strength aluminum bronze material, is widely recognized for its outstanding mechanical properties and superior corrosion resistance. It is particularly suitable for additive manufacturing and powder metallurgy processes where durability and resistance to harsh environments are essential.

Excellent Mechanical and Wear Resistance

CuAl10 alloy contains approximately 10% aluminum and 90% copper, forming a strong and stable microstructure. Key performance benefits include:

• High tensile and yield strength for load-bearing parts

• Superior wear resistance in abrasive environments

• Good impact resistance and dimensional stability

These characteristics make it a preferred choice for sliding components and mechanical assemblies.

Outstanding Corrosion Resistance

CuAl10 excels in resisting:

• Seawater corrosion, making it ideal for marine components

• Chemical attacks in acidic and alkaline environments

• Atmospheric oxidation over prolonged exposure

This resistance allows for long service life in pumps, valves, and offshore equipment.
