CuAl-based aluminum bronze alloys are high-performance specialized copper alloys known for their superior mechanical strength, excellent corrosion resistance, and long service life. Defined by various commercial and international standards such as ALBA 180-1, CW303G, CW305G, C61300, C61400, C61900, C62300, C62400, and AMS 4635, these alloys are reliably used even under the most demanding environmental conditions.
Aluminum bronze alloys stand out particularly in the marine, defense, aerospace, energy, petrochemical, and heavy industrial sectors, thanks to their high load-bearing capacity, friction resistance, and thermal stability.
Technical Advantages:
- High tensile and yield strength
- Excellent corrosion resistance in seawater and chemical environments
- Outstanding resistance to wear, impact, and friction
- Dimensional stability at elevated temperatures
- Suitable for welding and machining processes
- Long service life with minimal maintenance requirements
Main Application Areas:
Marine Industry: Ship propellers, underwater fittings, valve and pump bodies
Defense & Aerospace: Mechanical components operating under high loads, flight systems, armored elements
Energy & Chemical Plants: Acid-resistant valves and flanges, high-pressure system components
Heavy Industry: Gearboxes, bushings, rail system components, hot-working molds
Machinery Manufacturing: Sliding bearings, piston rods, friction-loaded moving components
Quality Assurance and Standards:
Aluminum bronze alloys comply with chemical compositions such as CW303G, CW305G, C61300, C61400, C61900, C62300, C62400, CuAl8Fe3, CuAl9Fe2, and CuAl10Fe1, and also meet aerospace standards such as AMS 4635.
All production is carried out under international quality-control systems and delivered with complete material analysis documents, certifications, and mechanical test results.
