Product Details

5086-H116 aluminium plate is a marine-grade aluminium product developed for shipbuilding, offshore structures, and corrosion-sensitive applications. The H116 temper provides improved resistance to exfoliation corrosion while maintaining the lightweight advantage, weldability, and forming performance of the 5xxx aluminium-magnesium alloy family.

Compared with standard aluminium tempers, 5086-H116 is specially controlled for marine service where long-term exposure to seawater and humid environments requires stable corrosion performance.

What Is 5086-H116 Aluminium Plate?

5086 aluminium belongs to the Al-Mg alloy series. Magnesium is the main alloying element, providing a good balance of strength, corrosion resistance, and weldability without requiring heat treatment.

Item	5086 Aluminium Characteristics
Alloy Series	5xxx aluminium-magnesium alloy
Main Alloy Element	Magnesium (approximately 3.5-4.5%)
Heat Treatment	Non-heat-treatable strengthening alloy
Main Advantage	Marine corrosion resistance and forming ability

Why Choose the H116 Temper for Marine Applications?

The H116 temper is a strain-hardened and stabilized condition developed for aluminium-magnesium alloys used in marine environments. It focuses on controlling microstructure and reducing the risk of exfoliation corrosion.

Improved resistance to exfoliation corrosion.
Suitable for prolonged seawater exposure.
Maintains good weldability.
Provides stable mechanical performance for marine structures.

5086-H116 Mechanical Properties

Mechanical properties may vary depending on thickness and production standards. Typical values are suitable for marine structural applications.

Property	Typical Range
Tensile Strength	275-340 MPa
Yield Strength	190-240 MPa
Elongation	Good forming capability

5086-H116 vs H321 vs O Temper Comparison

Temper	Characteristics	Typical Use
O	Soft annealed condition with maximum formability	Deep forming applications
H116	Marine corrosion-controlled temper	Ship and offshore structures
H321	Stabilized marine-grade temper	Marine plates and welded structures

5086-H116 vs 5083-H116

5086 and 5083 are both widely used marine aluminium alloys. The choice depends on strength requirements, forming conditions, and project specifications.

Comparison	5086	5083
Strength Level	Moderate	Higher strength
Formability	Excellent	Very good
Marine Performance	Excellent	Excellent
Selection Focus	Forming and corrosion resistance	Higher structural strength

Applications of 5086-H116 Aluminium Plate

Ship hull structures
High-speed boat components
Offshore platforms
Marine tanks and containers
Welded aluminium structures

Marine Certification and Traceability Requirements

For shipbuilding projects, material certification and traceability are often required. Buyers should confirm the available inspection documents before ordering.

Document	Purpose
Material Certificate	Confirms chemical composition and mechanical properties
Third-Party Inspection	Verifies quality requirements
Heat Number Traceability	Ensures production history tracking
