5083-H32/H111/H116 aluminium plaat

What Is 5083 Aluminum Sheet?

5083 Aluminum Sheet is a non-heat-treatable aluminum-magnesium alloy (AlMg4.5Mn0.7) supplied by Linsy Aluminum. It is one of the strongest work-hardenable grades and is widely specified for marine, offshore, and cryogenic service because of its excellent resistance to seawater corrosion and its ability to retain strength after welding. Common tempers include O, H111, H112, H116, and H321.

O	275 – 350	110 – 145	16 – 21	~75
H111	275 – 350	≥175	16	~75
H112	≥275	≥125	≥12	~75

H32	305 – 345	≥215	≥12	~85

Gids voor het kiezen van de juiste temperatuur

• O (gegloeid): maximum ductility and corrosion resistance; used where forming is required.
• H111 / H112: minor strain-hardened or as-fabricated; good general structural use.
• H116 / H321: strain-hardened and stabilized for marine plate and extrusions; the default choice for shipbuilding and offshore structures.
• H32: strain-hardened to half-hard; good for sheet requiring moderate strength and formability.

5083 is non-heat-treatable — tempers are produced by strain hardening and stabilization, not by solution heat treatment.

Belangrijkste kenmerken

Uitzonderlijke corrosiebestendigheid

Resists seawater, brine, and many chemicals; widely used where long service life in marine environments is required.

Hoge sterkte

One of the strongest non-heat-treatable aluminum alloys, with good strength-to-weight ratio.

Lasbaarheid

Excellent weldability with minimal loss of properties in the heat-affected zone.

Cryogenic Toughness

Retains toughness at low temperatures, suitable for LNG and cryogenic storage.

Toepassingen

• Shipbuilding and marine structures
• Pressure vessels
• Opslagtanks
• Offshore platform components
• Transport and cryogenic tanks

Opmerkingen over bewerking en oppervlakteafwerking

5083 welds well with conventional processes (TIG/MIG) and retains most of its strength in the weld zone. For welding filler, ER5183 or ER5356 wire is commonly used. The alloy has only moderate machinability compared with heat-treatable grades, and cutting tools should account for its gummy chip formation.

• Cutting: sawing, CNC machining, laser cutting
• Forming: good in O and soft tempers; springback increases with hardening
• Surface: mill finish standard; anodizing, polishing, powder coating, PVC film available
• Heat input during welding should be controlled to avoid softening of adjacent material

Kwaliteitsdocumenten en inspectie

Every 5083 order ships with a material test certificate (MTC) that reports the actual chemical analysis and mechanical results for the supplied lot. Third-party SGS test reports are available on request. Standard mill inspections cover dimensional tolerance, surface condition, and tensile verification per the ordered specification.

• MTC (EN 10204 3.1 or equivalent) with every order
• Dimensional and visual inspection at shipment
• Optional ultrasonic or penetration testing for plate and heavy sections
• RoHS and REACH documentation available on request
