3. Can 1xxx series aluminum be used in food-grade or chemical applications?
Yes. 1050, 1060, 1070, and 1100 alloys are high-purity, non-toxic, and corrosion-resistant, making them suitable for food processing equipment, kitchenware, storage tanks, and chemical vessels.
4. What is the electrical and thermal conductivity of these alloys?
1070 offers the highest electrical and thermal conductivity (~61% IACS), ideal for bus bars, heat exchangers, and electrical conductors.
1050 and 1060 provide very good conductivity for general electrical and thermal applications.
1100 has slightly lower conductivity but excellent corrosion resistance and workability.
5. Are surface treatments available?
Yes. All 1xxx series alloys can be anodized, mirror-polished, embossed, color-coated, or printed to meet decorative, protective, or functional requirements.
6. What are the typical dimensional tolerances?
Sheets/plates/coils: Thickness ±0.02–0.10 mm, Width ±1 mm, Flatness ≤3 mm/m.
Bars/rods: Diameter ±0.05–0.20 mm, Straightness ≤0.5% of length.
Custom tolerances are available for large-volume or high-precision orders.
7. Do you provide quality certificates?
Yes. We provide mill test certificates (MTC, EN10204 3.1), chemical composition analysis, and mechanical testing reports. Third-party inspection by SGS, BV, or TÜV can also be arranged.
8. What is the typical MOQ and lead time?
MOQ: 1–3 tons, depending on alloy, form, and size.
Lead time: 5–15 days for stock sizes; 15–30 days for custom specifications.
9. Can you provide custom cutting, slitting, or machining?
Absolutely. We offer cut-to-length sheets, slitted coils, CNC cutting, precision bar machining, and protective film lamination for international shipments.
