ALBA 390 is a specially engineered high-strength bronze alloy developed to deliver exceptional performance under extreme operating conditions such as high temperature, intense pressure, and friction. With its outstanding resistance to wear, corrosion, and impact loading, it provides long-lasting and reliable solutions for heavy-duty applications.
Widely used in defense, heavy industrial machinery, marine systems, rail transport, and petrochemical plants, ALBA 390 is designed to meet the most demanding engineering requirements.
Technical Advantages:
- High tensile and yield strength
- Strong resistance to wear, impact, and cavitation
- Stable mechanical properties at elevated temperatures
- Excellent corrosion resistance against seawater, acids, and aggressive chemicals
- Suitable for machining, forging, and welding processes
- Long service life with minimal maintenance requirements
Primary Application Areas:
Defense Industry: Armored system components, high-impact and friction-exposed mechanical joints
Marine Industry: Propeller shafts, valves, and seawater-exposed mechanical parts
Energy & Chemical Industry: Acid- and pressure-resistant valves, flanges, sealing components
Heavy Industry & Rail Systems: Bushings, gears, couplings, rail system components
Machinery Manufacturing: Friction bearings, piston rods, and high-load structural elements
Quality Assurance and Compliance:
ALBA 390 is manufactured in accordance with industrial quality requirements. All production batches are supplied with chemical composition reports, mechanical test results, and microstructure inspection certificates. The material fully complies with RoHS and REACH environmental standards.
