IX. よくある質問 (Q&あ)

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%. 加えて, corrosion resistance can be further enhanced through passivation treatment, and salt spray resistance time can reach more than 200 時間, 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:

O temper (annealed):
Best plasticity, elongation ≥10%, suitable for deep drawing and forming products such as aluminum foil containers and complex-shaped containers.
H22 / H24 temper (half-hard):
Balanced strength and plasticity, suitable for bending and bonding applications such as building insulation foil and packaging foil.
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, 厚みも含めて (0.014–0.5 mm), 幅 (100–1600 mm), 気性, 表面処理 (passivation, oil coating, エンボス加工), and packaging methods.
The minimum order quantity (MOQ) for regular specifications is 3 tons per specification.
For special customized specifications, MOQは 5 トン.
For long-term cooperative customers, the MOQ can be negotiated.

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

Each batch of products is provided with a material certificate (COA) and factory inspection report. According to customer requirements, FDA (food contact grade), REACH, RoHS, SGS third-party test reports, and ISO 9001 / ISO 22000 system certification documents can be provided to ensure that products meet compliance requirements of target markets and pass customs clearance smoothly.

Q5. How is transportation damage handled?

Q6. How should 3003 アルミホイルと 3004 aluminum foil be selected?

If the budget is limited and moderate strength is required, while corrosion resistance and formability need to be balanced (such as ordinary food containers, 建物の断熱材, 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.
