4×8 Aluminum Sheet
Time : 2026-10-09
4x8 Aluminum Sheet
A 4x8 aluminum sheet is a commonly requested flat-sheet size measuring 4 ft × 8 ft, or 48 × 96 inches. The exact metric conversion is 1219.2 × 2438.4 mm. 1220 × 2440 mm is a closely related commercial metric sheet size frequently requested for industrial fabrication.
Voyage Metal supplies aluminum sheet for industrial procurement in grades including 1050, 1100, 3003, 5052, 5083 and 6061. Final availability depends on alloy, temper, thickness, dimensional tolerance, surface requirement, quantity, processing and the applicable purchase specification.
Nominal size 4 ft × 8 ft
Imperial dimensions 48 × 96 in
Exact metric conversion 1219.2 × 2438.4 mm
Common metric request 1220 × 2440 mm
What Does 4x8 Aluminum Sheet Mean?
“4x8” describes the sheet width and length. It does not define the aluminum alloy, temper or thickness.
A complete purchase specification should normally identify the alloy, temper, thickness, finished dimensions, tolerance, surface condition and quantity .
For example, a 5052-H32 sheet and a 6061-T6 sheet can have the same 48 × 96 inch dimensions, while offering different forming, strength, machining and corrosion characteristics.
A practical RFQ may therefore read: 5052-H32, 3 mm × 1220 × 2440 mm or 6061-T6, 1/8 in × 48 × 96 in .

Which Aluminum Alloy Should You Choose?
The 4x8 size does not determine the aluminum grade. Select the alloy according to the fabrication process, required mechanical performance and service environment.
3003 Aluminum
A general-purpose Al-Mn alloy widely considered for formed sheet components, enclosures, equipment panels and general fabrication.
5052 Aluminum
An Al-Mg alloy often selected for a useful balance of corrosion resistance, strength, forming performance and weldability.
View 5052 Aluminum →5083 Aluminum
A higher-magnesium 5xxx alloy commonly considered for demanding welded structures and marine-related applications where strength and corrosion performance are important.
View 5083 Aluminum →6061 Aluminum
A heat-treatable Al-Mg-Si alloy frequently used for machining, structural fabrication and general engineering applications.
View 6061 Aluminum →Not Sure Which Grade to Specify?
Start with the service environment, forming or machining process, welding requirements, design strength and applicable specification.
Common Temper Examples
Temper affects strength, hardness, formability and fabrication behavior. It should always be specified together with the alloy.
| Alloy | Temper Examples | Purchasing Consideration |
|---|---|---|
| 1050 | O / H14 / H24 | Confirm forming condition and required mechanical properties. |
| 1100 | O / H14 / H24 | Frequently considered for forming and general sheet fabrication. |
| 3003 | H14 / H24 | Select according to forming and stiffness requirements. |
| 5052 | H32 / H34 | Confirm required forming, bending and strength. |
| 5083 | H111 / H116 / H321 | H116 and H321 are especially relevant where applicable marine specifications and corrosion-performance requirements apply. |
| 6061 | T6 / T651 where applicable | T6 is widely specified; T651 is typically associated with applicable stress-relieved plate conditions and should be confirmed against product form and thickness. |
Temper examples are provided for purchasing reference only. Final availability depends on product form, alloy, dimensions and applicable specification.

How Much Does a 4x8 Aluminum Sheet Weigh?
Theoretical weight depends on actual length, width, thickness and alloy density .
For preliminary purchasing calculations, a nominal aluminum density of 2700 kg/m³ can be used as a general reference. Exact density varies by alloy.
Metric Weight Formula
Weight (kg) =
Length (m) × Width (m) × Thickness (m) × Density (kg/m³)
The following table uses the exact converted 48 × 96 inch dimensions of 1219.2 × 2438.4 mm and a nominal density of 2700 kg/m³.
| Thickness | Sheet Size Used | Theoretical Weight |
|---|---|---|
| 1.0 mm | 1219.2 × 2438.4 mm | ≈ 8.03 kg / sheet |
| 1.5 mm | 1219.2 × 2438.4 mm | ≈ 12.04 kg / sheet |
| 2.0 mm | 1219.2 × 2438.4 mm | ≈ 16.05 kg / sheet |
| 3.0 mm | 1219.2 × 2438.4 mm | ≈ 24.08 kg / sheet |
| 3.175 mm (1/8 in) | 1219.2 × 2438.4 mm | ≈ 25.49 kg / sheet |
| 4.0 mm | 1219.2 × 2438.4 mm | ≈ 32.11 kg / sheet |
| 6.0 mm | 1219.2 × 2438.4 mm | ≈ 48.16 kg / sheet |
| 6.35 mm (1/4 in) | 1219.2 × 2438.4 mm | ≈ 50.97 kg / sheet |
The figures above are theoretical estimates, not certified shipment weights.
Actual weight can vary with alloy density, thickness tolerance and measured dimensions. Use the specified alloy and actual supplied dimensions for final logistics calculations.
Material Standards and Inspection
The applicable material standard should be identified when chemical composition, mechanical properties, product tolerances or certification requirements must be formally verified.

4x8 Aluminum Sheet FAQ
Is 4x8 aluminum sheet exactly the same as 1220 × 2440 mm?
No. 48 × 96 inches converts exactly to approximately 1219.2 × 2438.4 mm. 1220 × 2440 mm is a closely related commercial metric sheet size, but it is not mathematically identical.
Which alloy should I choose for a 4x8 aluminum sheet?
There is no single best alloy. 3003 is often considered for general fabrication; 5052 where forming and corrosion resistance are important; 5083 for suitable marine and welded structural applications; and 6061 for many structural and machining uses.
Can I order a custom thickness?
Custom thicknesses can be reviewed. Availability depends on alloy, temper, dimensions, tolerance, quantity and applicable specification.
How is 4x8 aluminum sheet weight calculated?
Multiply length × width × thickness × density using consistent units. A nominal density of approximately 2700 kg/m³ can be used for preliminary calculations, but actual density varies by alloy.
Can a 4x8 aluminum sheet be cut to a smaller size?
Cut-to-size requirements can be reviewed according to alloy, temper, thickness, finished dimensions and required tolerance.
What information should I include in an RFQ?
Provide alloy, temper, thickness, width, length, quantity, applicable standard, tolerance, surface requirement, processing, inspection requirement, packing requirement and destination.
