Mechanical Properties

Temper Designation and Definition: H116

• H116 temper denotes the stabilized condition of the 5083 alloy sheet to be used without strain-ageing, which safeguards the material’s resistance to sensitization in marine environments.
• After rolling and annealing, the material undergoes strain hardening, followed by stabilization heat treatments unique to the temper H116.
• Alleviates the risk of exfoliation corrosion, specifically vital for marine-grade aluminum subjected to saltwater.

Implementation and Quality Standards

• CCS Certification: Aluminum sheet 5083 H116 comes with a Certification by CCS that confirms compliance with marine engineering standards, ensuring material traceability and factory audits.
• Production Standards:
• GB/T 15115-2008 (Aluminium and aluminium alloy sheets)
• ASTM B928/B928M
• ISO 6361:2012
• EN AW-5083 standards as per EN 485-2
• Corrosion Resistance: Designed to withstand harsh saltwater and marine atmospheres, ideal for hulls, decks, and superstructures.
• Welding & Fabrication: Suitable for gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and has excellent cold working and machining capabilities.

Benefits for Marine Applications

1. Exceptional Corrosion Resistance: Due to the magnesium-rich chemical make-up, the 5083 alloy is highly resilient against seawater corrosion and exfoliation.
2. High Strength with Toughness: The H116 temper preserves excellent mechanical strength while maintaining ductility necessary for shaping and impact-resistance on maritime structures.
3. Lightweight: Compared with steel, the lower density means improved fuel efficiency and payload capacity.
4. Certified Reliability: CCS certification validates conformity to strict safety and performance metrics critical in the marine industry.
5. Versatility: Works well across various marine exterior and interior applications, including bulkheads, decks, pressure vessels, and structural components.
