What is Marine Grade 5086 H116 aluminum plate?

Alloy and temper overview

Mariene kwaliteit 5086 H116 aluminum plate belongs to the 5xxx series of aluminum alloys, which are aluminum-magnesium alloys known for their excellent corrosion resistance in marine environments.

De 5086 legering typically contains approximately 4–5% magnesium, with the remainder aluminum and small trace elements.

This composition gives 5086 good strength while maintaining excellent resistance to seawater corrosion, particularly when compared with many other alloys.

The H116 temper is a specific strain-hardened condition. In aluminum temper designations, the “H” family indicates work hardening to a stable state.

H116 means the material has been strain-hardened (and possibly lightly worked or partially annealed depending on the precise processing route) to a defined strength level, without full stabilization by annealing.

The result is a plate that retains higher strength than fully annealed grades (such as F or O tempers) while still maintaining reasonable ductility and good formability for plate fabrication, snijden, buigen, and joining.

How H116 differs from other tempers

• H116 versus. H32 or H34: H116 is generally a lower hardness and higher ductility condition than H32, H34, or fully strain-hardened tempers that are more common in non-marine 5xxx plates. H32/H34 is more strongly strain-hardened and tends to have higher yield strength but less elongation and formability.
• H116 versus. H116 in other alloys: The exact response of temper designations can vary slightly from alloy to alloy due to solid solution strength, precipitate formation, and work-hardening behavior. Echter, the core concept remains: H116 provides a practical balance of strength, verwerkbaarheid, and corrosion resistance for marine applications.

Typical compositions

The precise chemical composition for 5086-H116 depends on the producer and production lot, but typical ranges for the key elements are:

• Magnesium (mgr): approximately 4.0–4.9%
• Silicium (En): trace amounts, usually well under 0.8%
• Mangaan (Mn): trace to moderate levels (often under 0.8%)
• Ijzer (Fe): usually under 0.7–1.0% in practice
• Andere elementen (chroom, zink, koper): kept to minimums, usually in trace amounts
• Aluminium (Al): evenwicht

Opmerking: The exact composition should be confirmed via the producer’s certified mill test report (MTR) or alloy data sheet. The ranges above reflect common practice for 5086 alloys and are intended to provide context for performance expectations rather than a guaranteed specification.

Mechanical properties and corrosion resistance

Mechanische eigenschappen

Material performance varies by supplier, verwerken, en dikte. The following ranges summarize common expectations for 5086-H116 plate in the thickness ranges typically used for marine hull plates (roughly 3–20 mm, with thicker plates also available):

• Opbrengststerkte (YS): approximately 95–145 MPa (14–21 ksi)
• Ultieme treksterkte (UTS): approximately 230–290 MPa (33–42 ksi)
• Verlenging bij breuk (A50 or A80 depending on thickness and standard): around 10–15% in thinner gauges, decreasing slightly as thickness increases
• Hardheid (Vickers or Brinell): gematigd, reflecting the balance between strength and formability

Practical takeaway: 5086-H116 offers sufficient yield strength for structural plates while maintaining ductility for forming and repair.

In thin sheets or heavily worked sections, the apparent strength can vary, but the alloy’s ability to absorb energy without brittle failure remains advantageous in marine environments.

Corrosion resistance in marine environments

• Saltwater resistance: 5086 is exceptionally corrosion resistant in saltwater, due to the protective aluminum oxide film and the beneficial effect of magnesium on passivation. This makes 5086-H116 an ideal choice for hull plating, dekken, bovenbouw, and other exposed surfaces.
• Galvanic compatibility: When used with appropriate coatings and compatible fasteners (bijv., aluminum or stainless steel, with isolators where required), 5086-H116 plates contribute to longer service life and easier maintenance in harsh marine atmospheres.
• Stresscorrosie kraken: The high Mg content and stable temper reduce susceptibility to stress corrosion cracking in many seawater service conditions, though design and environment still matter. Avoid aggressive chloride concentrations and consider protective coatings or cathodic protection where appropriate.

Weldability and formability

• Lasbaarheid: Excellent weldability with commonly used filler metals such as ER5356 and ER5183. Welding 5086-H116 typically yields good joint strength, with corrosion resistance preserved at the weld zone when proper techniques are used.
• Vervormbaarheid: Good formability for hull plating, dekken, and other panels. The H116 temper maintains ductility that enables bending, rollen buigen, and hydroforming in many cases, though thicker sections require standard forming precautions to minimize cracking or wrinkling.
• Post-weld heat treatment: Unlike some heat-treatable alloys, 5xxx series generally do not require post-weld heat treatment. Echter, some fabricators perform post-weld heat treatment on thicker plates to relieve residual stresses, depending on specifications.

Fabrication and joining considerations

Cutting and machining best practices

• Snijden: For marine-grade 5086-H116, plasma, laser, or waterjet cutting typically yields clean edges with minimal heat-affected zone (Hazel). Thin to mid-thickness plates cut well with these methods.
• Drilling: Use sharp high-speed steel or carbide drill bits; apply coolant if noise or heat is observed, and countersink as needed with appropriate tools to avoid edge cracking.
• Ontbramen: Clean burrs to minimize corrosion initiation at edges.

Welding procedures and filler metals

• Common weld methods: Gas metal arc welding (GMAW/MIG) wordt veel gebruikt. Gas tungsten arc welding (GTAW/TIG) is used for precision joints or where aesthetics matter.
• Filler metals: ER5356 is a common choice for 5086; ER5183 is another option depending on joint design and corrosion considerations.
• Weld design considerations: Ensure proper joint geometry to avoid stress concentrations. Preheat is typically not required for 5086-H116, and post-weld heat treatment is usually unnecessary, but consult welding procedure specs (WPS) for thickness-specific guidance.

Forming and bending

• Bending radius: Plan on generous bend radii to avoid cracking in the heat-affected zone, especially for thicker plates.
• Springback: Expect some springback in cold-worked states; verify with pilot bends and adjust tooling accordingly.
• Surface support: Use soft, uniform backing materials to reduce tearing and wrinkling in thin-laminate panels.

Surface finishing and coating compatibility

• Afwerkingen: Anodizing is not typical for 5xxx series to maintain corrosion resistance; instead, mechanical polishing and protective paint systems are common.
• Coatings: Marine-grade coatings with proper surface preparation work well; ensure compatibility with aluminum to prevent galvanic corrosion when joined to other metals.
