Aluminum Sheet

Aluminum sheet is flat-rolled product ordered by alloy, full temper, thickness, width, length, tolerance, flatness, surface class, grain direction and protective-film requirement.

Common grades

Grade + product

5052 Aluminum Sheet

Formable, non-heat-treatable 5052 sheet for general fabrication; specify O, H32, H34 or another registered temper rather than alloy number alone.

Grade + product

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.

Grade + product

6061 Aluminum Sheet and Plate

Heat-treatable 6061 sheet and plate for structural, machined and general engineering parts; T6, T651 and related suffixes are not interchangeable ordering shorthand.

Specifications and dimensions

Thickness, width and length with alloy-, temper- and thickness-specific tolerances
Flatness, diagonal, edge, grain direction and residual-stress control where required
Mill finish, anodizing quality, brushed finish, tread pattern or protective film

Standards and supply condition

ASTM B209/B209M for aluminum and aluminum-alloy sheet and plate
EN 485 series for applicable European flat-rolled aluminum products

Manufacturing and processing

Cast slab is homogenized, hot rolled and cold rolled to gauge before final heat treatment or strain hardening.
Leveling, stretching, shearing, sawing, surface finishing and film application complete the order.

Typical applications

Transport bodies and marine fabrication
Enclosures, signs and architectural panels
Machined components and general sheet-metal work

Quality and acceptance controls

Verify the registered alloy and complete temper designation against the certificate and ordered product standard.
Check dimensions, applicable tolerance table, flatness or straightness, surface class, edge and permitted defects.
Control film, interleaving, dryness, contact materials, handling and export packing to prevent staining and damage.

Include in your RFQ

Registered alloy and complete temper designation
Governing product specification and unit system
Dimensions, tolerances, quantity and grain-direction requirement
Surface class, finish, film, edge and processing requirement
Mechanical, conductivity, ultrasonic or other test and certificate requirements
Packing, moisture protection, destination and delivery term

Selection limits

Sheet and plate terminology follows the ordered standard and thickness range; it is not universal across markets.
Marine or aerospace use requires the exact product specification, temper and supplementary controls, not alloy reputation alone.
