Looking for a Reliable 3003 Aluminum Foil Factory?

When sourcing 3003 aluminum foil, you are not just buying a roll of metal. You are buying formability, corrosion resistance, and strength retention. As a professional 3003 aluminum foil factory, we know this alloy well. It contains about 1.2% manganese. This gives it 10% higher strength than 1000 series foil, while keeping good workability.

Mingtai Aluminum produces 3003 foil in thicknesses from 0.006mm to 0.2mm. We supply it in various tempers, including O, H14, H16, H18, H19, H22, and H24. These meet the forming needs of different industries.

Technical Specifications of 3003 Aluminum Foil

A reliable factory must follow strict standards for chemical makeup and mechanical properties. The manganese gives 3003 a stable grain structure. This makes it good for deep drawing without cracking.

Main Uses of 3003 Aluminum Foil

Why do buyers look for a specialized supplier? Because the strength and corrosion resistance of 3003 cannot be matched by pure aluminum.

Honeycomb Core Material

3003-H19 foil has a high strength-to-weight ratio. It is the standard for aerospace and building honeycomb structures. The foil must have stable elongation. This ensures it expands into hexagonal cells without cracking.

Electronic Foil

For capacitors and electronic parts, the foil needs high purity and a clean surface. The factory must control rolling oil residue to keep electrical properties stable.

Food Containers and Closures

For food containers, 3003 foil in O or H22 temper is soft but firm. It can crimp over lids for a good seal, yet still hold the container's shape.

How to Check a 3003 Aluminum Foil Factory

You can judge a factory's capability by looking at these technical points:

Raw Material Control

- Manganese content must stay between 1.0% and 1.5%. Too low, and strength drops. Too high, and it gets hard to work with.

- We use high-quality aluminum ingots. This ensures stable melt quality and uniform chemistry.

Annealing Furnace Consistency

- Making O-temper soft foil needs precise heat treatment. Good furnace temperature control is vital for grain structure.

- A uniform grain structure means better yields for your deep drawing work.

Thickness Tolerance and Surface

- A good factory controls thickness within ±5%.

- Honeycomb foil is sensitive to thickness changes. Small variations can cause core crushing during pressing.

- We ensure clean ends. Surface oil film is controlled to Grade B or higher. This prevents corrosion during shipping.

FAQ

Q: What is the difference between 3003 foil and 1100 or 8011 foil?

A: 3003 contains about 1.2% manganese. It is about 10% stronger than 1100 but still forms well. Compared to 8011, 3003 has better corrosion resistance and weldability. This makes it better for structural uses like honeycomb cores.

Q: Can 3003 foil be used for deep drawn containers?

A: Yes. Fully annealed (O temper) 3003 foil has high elongation and low tensile strength. This is good for deep drawing food containers. If you need strength after forming, choose H22 or H24 temper.

Q: What thickness of 3003 honeycomb foil does your factory make?

A: For honeycomb cores, we often make H19 temper foil. The thickness is usually 0.02mm to 0.10mm. We can also make aerospace grades from 0.017mm to 0.15mm based on orders.

Q: How do you ensure quality for electronic grade 3003 foil?

A: Electronic foil needs a very clean surface. We strictly control the annealing process. This ensures good degreasing and low rolling oil residue. When slitting, we keep burrs to a minimum to meet capacitor winding needs.
