5083 Aluminum Sheet and Plate
Higher-strength, non-heat-treatable 5083 sheet and plate for welded and marine fabrication; marine H116/H321 orders require the applicable corrosion-performance controls.
03Grade-product
Standards and supply condition
- ASTM B209/B209M for general sheet and plate supply
- ASTM B928/B928M or applicable classification rules for marine H116/H321 plate when ordered
Manufacturing and processing
- Rolling, heat treatment or strain hardening establish the ordered temper before leveling and cutting to length.
- Sawing, shearing, laser or water-jet cutting, forming, machining, welding and anodizing must be matched to alloy and temper.
Typical applications
- Marine hull and superstructure fabrication
- Cryogenic, transport and welded storage equipment when engineered
- High-strength fabricated panels and structures
Quality and acceptance controls
- Match alloy, exact temper, lot or heat identity, dimensions and ordered product specification to the certificate.
- Verify thickness or wall tolerance, flatness or straightness, surface class, permitted defects and traceability.
- Agree mechanical testing, corrosion testing, ultrasonic examination, conductivity or third-party inspection where the service requires it.
Include in your RFQ
- Exact alloy or grade and governing product specification
- Product form, dimensions, tolerances and quantity
- Delivery condition or temper and required surface finish
- Fabrication route, service environment and design standard
- Testing, inspection, certificate and traceability requirements
- Packing, marking, destination and required delivery date
Selection limits
- Alloy number without the exact temper is incomplete for strength, forming, machining and welding decisions.
- Published dimensional ranges are procurement guidance, not a stock promise; the mill capability and ordered specification control acceptance.
