Aluminum sheet 8x4, or 4x8 as folks in the industry call it, is a total rockstar for all kinds of projects. It’s got a great size, plays nice with tons of alloys, and can handle different finishes like a champ. Whether you’re building homes, crafting cars, or making factory parts, this sheet is light, sturdy, and works for just about anything.

What’s Up with Aluminum Sheet 8x4 Size?
Size and Thickness Options
An 8x4 aluminum sheet is 8 feet long and 4 feet wide. That’s roughly 2440 mm by 1220 mm. Companies like MINGTAI ALUMINUM let you pick custom sizes. You can go super thin at 0.1 mm or beefy at 500 mm. Widths range from 100 mm to 2650 mm, and lengths hit 500 mm to 16000 mm. Basically, you get what fits your job.
Nailing the Measurements
When you need precision—like for airplane bits or building panels—size matters big time. Manufacturers stick to strict rules like ASTM B209. These keep the thickness, flatness, and edges dead-on. Spot-on sheets make your work easier and your stuff more reliable.
How Heavy Is It?
Weight depends on thickness and alloy. Aluminum’s density is about 2.7 g/cm³. A 3mm thick 8x4 sheet comes in at around 32.5 kg. Knowing the weight helps you plan shipping or check if your structure can handle it.
Awesome Features of Aluminum Sheet 8x4
What’s It Made Of?
You can get 8x4 sheets in different alloys for whatever you’re doing. The 3003-H14 bends like a dream and fights off rust. The 5052-H32 is a beast in salty ocean air. The 6061-T651 is tough and easy to cut or shape. There’s also 2024 for serious strength and 5251 for stuff like trains.
Finish Options for Looks and Strength
The finish changes how the sheet looks and holds up.
Mill Finish
This is the no-frills look straight from rolling. It’s smooth but plain. Use it as is or jazz it up later.
Anodized Finish
Anodizing makes it super rust-proof and lets you add colors. It puts a tough layer on the surface.
Painted or Coated Finishes
Paint or special coatings keep it safe from UV rays and wear. Perfect for signs or building exteriors.
Strength and Cool Traits
Each alloy and treatment gives sheets its own vibe. The 6061-T651 is strong, rust-resistant, and easy to weld or machine. It takes heat like a pro and won’t crack. The 3003-H14 bends easily but isn’t as tough, so it’s great for lighter jobs.
Rust-Proof and Built to Last
Aluminum’s awesome at dodging rust. The 5052-H32 shines in salty marine spots. Anodized finishes make it even tougher in rough weather.

The 3003-H14 has a nice, semi-shiny look. It’s perfect for signs that need to pop and last outside.
How to Pick Aluminum Sheet 8x4
Choose the Right Alloy
Pick an alloy that matches your project. Think about strength, rust risks, welding, shaping, heat, and your budget. For example:
- Grab 5052-H32 for ocean vibes.
- Go 6061-T651 for strong, precise parts.
- Pick 3003-H14 for shapes that don’t need mega strength.
Cost vs. Perks
Fancier alloys might hit your wallet harder at first. But they can save cash by lasting longer or needing less fixing, especially in tough spots like the sea or factories.

FAQ
Q: How can I tell if an 8x4 aluminum sheet fits my project?
A: Think about your project’s space. Consider your cutting needs too. The 8x4 size (eight feet by four feet) is ideal for standard uses. Think panels or signs. But check if your gear or design needs smaller or bigger sheets. Talk to your supplier. Ask if custom cuts save money for your specific job.
Q: What tools work best for cutting or shaping 8x4 aluminum sheets?
A: Use a circular saw. Make sure it has a carbide-tipped blade. Metal shears also give clean cuts. For bending, a brake press does the job well. Always wear safety gear. This includes gloves and eye protection. Check your tools work with aluminum. This avoids hurting the sheet.
Q: How should I store 8x4 aluminum sheets to keep them safe?
A: Keep them flat. Pick a dry, covered spot. This stops scratches and bending. Place spacers between sheets. This prevents surface damage. Keep sheets away from wet areas. Keep them away from chemicals too. This protects their finish. It’s extra important for sheets with unfinished surfaces.
