What Is a 4×8 Aluminum Sheet?
A 4×8 aluminum sheet is a flat aluminum sheet with a width of 4 feet and a length of 8 feet. It is one of the most common sheet sizes because it matches standard cutting machines, storage racks, trucks, CNC equipment, and fabrication workflows.
This size offers enough surface area for large panels while remaining practical for handling, cutting, packing, and shipping. In international orders, buyers may also describe the same product as 48 x 96 aluminum sheet or 1220 x 2440 aluminum sheet.
| Size Format | Measurement |
| Feet | 4 ft x 8 ft |
| Inches | 48 in x 96 in |
| Millimeters | About 1220 mm x 2440 mm |
Common Thickness Options for 4×8 Aluminum Sheet
Thickness is one of the most important specifications when buying aluminum sheet. It affects strength, weight, bendability, processing cost, shipping cost, and final application performance.
| Thickness | Approx. mm | Common Use |
| 0.020 in | 0.5 mm | Light decorative panels, signs, covers |
| 0.032 in | 0.8 mm | Interior panels, light enclosures |
| 0.040 in | 1.0 mm | Trim, signs, light fabrication |
| 0.063 in | 1.6 mm | General sheet metal work |
| 0.080 in | 2.0 mm | Cabinets, machine covers, vehicle panels |
| 0.100 in | 2.5 mm | Stronger covers and formed parts |

| 0.250 in | 6.35 mm | Thick sheet or light plate applications |
How to Choose the Right Thickness
For most general applications, 1 mm to 3 mm aluminum sheet is commonly used. For stronger structural parts, buyers often choose 3 mm to 6 mm or move to aluminum plate. The best thickness should be selected according to load, span, bending requirements, fixing method, and surface expectations.
| Application | Recommended Thickness | Factory Buying Tip |
| Advertising signs and light panels | 0.8-1.5 mm | Confirm flatness and surface protection if the panel is visible. |
| Machine covers and cabinets | 1.5-3.0 mm | 2 mm and 3 mm are common choices for strength and easy fabrication. |
| Vehicle and trailer panels | 2.0-4.0 mm | 5052 is often selected when corrosion resistance and fatigue strength matter. |
| Marine panels and fuel tanks | 2.0-6.0 mm | Use 5052 or 5083 and confirm welding, saltwater exposure, and inspection needs. |
| Machined or structural parts | 3.0-6.35 mm+ | 6061-T6 is common, but bending radius and machining allowance should be checked. |
How Much Does a 4×8 Aluminum Sheet Weigh?
Weight depends mainly on thickness and alloy density. Aluminum is much lighter than steel, which is one reason it is widely used in transportation, construction panels, marine parts, equipment covers, and machinery housings.
Practical formula: length (m) x width (m) x thickness (mm) x 2.71 = approximate weight in kg. For a 1220 x 2440 mm sheet, 1 mm thickness is about 8 kg per sheet.
| Thickness | Approx. Weight per 4×8 Sheet |
| 0.040 in / 1.0 mm | About 8 kg |
| 0.063 in / 1.6 mm | About 13 kg |
| 0.080 in / 2.0 mm | About 16 kg |
| 0.125 in / 3.0 mm | About 24 kg |
| 0.190 in / 4.8 mm | About 39 kg |
| 0.250 in / 6.35 mm | About 51 kg |
Actual weight may vary slightly depending on alloy, thickness tolerance, and exact sheet size.
Popular Aluminum Grades for 4×8 Sheets
Different aluminum grades have different strength, corrosion resistance, formability, weldability, machinability, and surface performance. Choosing the right grade is more important than simply choosing the cheapest sheet.
| Alloy | Main Features | Typical Applications |
| 1050 / 1060 | High purity, excellent formability and corrosion resistance | Signs, reflectors, electrical parts |
| 1100 | Soft, easy to form, good corrosion resistance | Food equipment, panels, decorative use |
| 3003 | Good corrosion resistance, stronger than 1000 series | Roofing, cabinets, tanks, general sheet metal |
| 5052 | Excellent corrosion resistance and fatigue strength | Marine parts, vehicle panels, fuel tanks |
| 5083 | High strength and marine corrosion resistance | Shipbuilding, pressure vessels |
| 6061 | Good strength, weldability, machinability | Structural parts, machinery, fixtures |
| 6063 | Good surface finish and corrosion resistance | Architectural panels, decorative applications |
| 7075 | Very high strength | Aerospace and high-stress components |
How to Choose the Right Alloy
If your project needs easy bending and general corrosion resistance, 3003 is often suitable. If corrosion resistance is critical, especially in marine or humid environments, 5052 is usually a better choice. If strength and machining performance matter more, 6061 may be preferred.
| Buyer Need | Recommended Alloy | Reason |
| Lowest practical cost for general sheet metal | 3003 | Good formability and corrosion resistance at a competitive cost. |
| Marine, outdoor, or humid environments | 5052 / 5083 | Better corrosion resistance and fatigue performance. |
| Machining, fixtures, or higher strength | 6061 | Good strength, machinability, and weldability. |
| Decorative or architectural surface | 5052 / 6063 | Good surface quality and corrosion resistance. |
| High-stress lightweight parts | 7075 | Very high strength, but higher cost and lower formability. |
3003 vs 5052 vs 6061 Aluminum Sheet
| Alloy | Strength | Corrosion Resistance | Formability | Best For |
| 3003 | Medium-low | Good | Excellent | General sheet metal, roofing, cabinets |
| 5052 | Medium | Excellent | Good | Marine, vehicle panels, tanks |
| 6061 | Medium-high | Good | Moderate | Structural parts, machinery, fixtures |
| Factory Recommendation For repeated OEM orders, send the drawing, application, bending radius, surface requirement, and quantity first. A supplier can then recommend alloy, temper, tolerance, protective film, and cutting method more accurately. |
How Temper Affects 4×8 Aluminum Sheet
Temper describes the heat treatment or work-hardening condition of aluminum. It affects hardness, strength, bending performance, machinability, and whether cracking may occur during forming.
| Temper | General Meaning | Common Use |
| O | Annealed, soft | Deep drawing, bending, forming |
| H14 | Strain hardened, half hard | General sheet metal work |
| H24 | Strain hardened and partially annealed | Panels, fabrication, moderate forming |
| H32 | Work hardened and stabilized | Marine and corrosion-resistant applications |
| T6 | Heat treated, higher strength | Structural and machined parts |
For bending or forming, softer tempers are usually easier to process. For structural or machined parts, harder tempers such as T6 may be selected.
Surface Finish Options
Surface finish affects appearance, corrosion resistance, processing, and final product quality. If the sheet will be used for visible panels or decorative parts, surface quality should be confirmed before purchase.
| Surface Finish | Description | Typical Use |
| Mill finish | Natural aluminum surface | General fabrication |
| Brushed finish | Directional surface texture | Decorative panels, appliances |
| Anodized finish | Oxide layer for protection and color | Architecture, electronics, decorative parts |
| Painted finish | Coated surface | Roofing, signage, wall panels |
| Embossed finish | Patterned surface | Flooring, anti-slip panels |
| Protective film | Temporary film protection | Cutting, bending, shipping protection |
What Affects Aluminum Sheet 4×8 Price?
When buyers search for aluminum sheet 4×8 price, they often expect one fixed number. In real quotations, price changes according to raw aluminum market prices, alloy selection, thickness, order quantity, processing requirements, and export packing.
| Price Factor | Why It Matters |
| Alloy grade | 5052, 6061, and 7075 usually cost more than 3003 or 1100. |
| Thickness | Thicker sheets use more aluminum and increase material weight. |
| Temper | Special tempers may require additional processing or limited stock. |
| Surface finish | Anodized, painted, brushed, or film-protected surfaces increase cost. |
