ALBA 280 is a high-performance aluminum bronze alloy engineered for heavy-duty applications where wear, impact, and corrosion resistance are required simultaneously. With a composition enriched with aluminum, iron, and nickel, this alloy provides excellent mechanical properties and long service life, making it a preferred choice for demanding environments such as marine, defense, energy, and heavy machinery industries.
It delivers outstanding performance in moving components exposed to friction, as well as in elements that must withstand high pressure and elevated temperatures. In addition, ALBA 280 exhibits superior resistance to seawater and chemically aggressive environments.
Technical Advantages:
- High tensile and yield strength
- Exceptional resistance to wear, impact, and cavitation
- Superior corrosion resistance in seawater and aggressive chemical environments
- Thermal stability with a low coefficient of expansion
- Suitable for machining and welding processes
- High load-carrying capacity
Main Application Areas:
Marine Industry: Propeller shafts, valve bodies, pump components, fittings
Defense & Aerospace: Armored system components, impact-absorbing parts, landing gear elements
Energy & Chemical Industry: Acid-resistant flanges, high-temperature valve components
Machinery & Heavy Industry: Gears, bushings, rail system components, couplings
Automotive & Transportation: Wear-resistant bearings and moving elements
Quality Assurance and Compliance:
ALBA 280 is manufactured in accordance with international quality control standards. Each production batch is supplied with chemical composition analysis, mechanical test reports, and microstructure inspection certificates. The alloy complies with environmental regulations such as RoHS and REACH.
