IX. Frequently Asked Questions (Q&A)

Q1. Why does 3003 aluminum foil have better corrosion resistance than pure aluminum foil?

3003 aluminum foil belongs to the Al–Mn alloy series. The manganese content is controlled at 1.0–1.5%, which forms a more stable alloy microstructure on the surface of the aluminum foil, effectively blocking the intrusion of oxygen and moisture. Compared with 1235 pure aluminum foil, its corrosion resistance is improved by more than 40%. Bukod pa rito, corrosion resistance can be further enhanced through passivation treatment, and salt spray resistance time can reach more than 200 mga oras, making it suitable for humid and outdoor environments.

Q2. How should different tempers of 3003 aluminum foil be selected?

Selection should be based on processing requirements and strength requirements:

  1. O temper (annealed na nga ba):
    Best plasticity, elongation ≥10%, suitable for deep drawing and forming products such as aluminum foil containers and complex-shaped containers.
  2. H22 / H24 temper (half-hard):
    Balanced strength and plasticity, suitable for bending and bonding applications such as building insulation foil and packaging foil.
  3. H18 temper (full hard):
    Highest strength (≥190 MPa), suitable for applications with high strength requirements such as electronic foil and honeycomb core foil.

Q3. Does the product support customization, and what is the minimum order quantity?

Full customization is supported, including thickness (0.014–0.5 mm), width (100–1600 mm), pag-uugali, surface treatment (passivation, oil coating, embossing), and packaging methods.
The minimum order quantity (MOQ) for regular specifications is 3 tons per specification.
For special customized specifications, ang MOQ ay 5 tonelada.
For long-term cooperative customers, the MOQ can be negotiated.

Q4. What international certifications and test reports can be provided?

If the budget is limited and moderate strength is required, while corrosion resistance and formability need to be balanced (such as ordinary food containers, pagkakabukod ng gusali, and electronic foil), 3003 aluminum foil is recommended, offering better cost performance.
If higher strength, impact resistance, and deep drawing performance are required (such as pressure-resistant containers and high-end building curtain walls), 3004 aluminum foil can be selected, but its cost is 15–20% higher than that of 3003. Samples of both alloys can be provided for testing and comparison.

Q7. What are the payment terms and delivery cycle?

Payment terms:
Standard orders adopt 30% advance payment (T/T) at 70% balance payment against the copy of bill of lading. For long-term cooperative customers, letter of credit (L/C) payment can be negotiated.
