Import 3003 Aluminium Foil 1mm Thick Roll 3004 — Buy in wholesale FOB from Supplier in China

3003/3004 aluminium alloy foil from Henan Mingtai Technology Development Co., Ltd is supplied in continuous coil form at 1.0 mm thickness, though the source indicates the company's standard foil range extends from 0.015 mm to 0.20 mm, suggesting this 1 mm offering may be a heavier-gauge variant or specialised product. The Al-Mn alloy system provides corrosion resistance and formability suited to industrial packaging, thermal insulation, and construction end-uses, with 3004 offering slightly higher magnesium content than 3003 for enhanced strength. Available tempers include O, H12, H14, H16, H22, H24, and H26, with width capability from 100 mm to 1600 mm and coil-length supplied as continuous (C).

The 3003 alloy is not heat-treatable and develops strength solely through cold working, with typical tensile strength of 140-180 MPa in H24 temper and typical yield strength of 115-160 MPa. Thermal and electrical conductivity are lower than pure aluminium but adequate for heat-exchanger and insulating applications; typical thermal conductivity is 159 W/(m·K) at 25°C. Surface quality is controlled through a flatness control system mentioned in the source, aimed at precision for electronic and packaging applications. The 1 mm thickness positions this material at the heavy end of foil products, overlapping with light-gauge sheet, and it is suitable for applications requiring greater rigidity than standard household foil while retaining roll-form convenience.

Primary applications span honeycomb-core panels for aerospace and transport, building insulation laminates, flexible packaging barriers, and battery soft-packaging films where the alloy's weldability and corrosion resistance are valued. The source cites monthly output of 65,000 tonnes and annual capacity of 770,000 tonnes, indicating substantial production scale, though buyers should verify current allocation and lead times for this specific gauge. The supplier's location in Zhengzhou's Hi-Tec Industrial Zone places it in Henan Province, a major Chinese aluminium production region with access to inland and coastal logistics routes. Buyers should confirm whether this 1 mm product is drawn from standard foil stock or represents a separate product line, and what minimum order quantities apply.

Henan Mingtai Technology Development Co., Ltd is headquartered at Y19 Building, Changchun Road, Hi-Tec Industrial Zone, Zhengzhou, Henan Province, China, postal code 451200. The company holds harbour-tier verification status. The source describes the firm as an A-share listed entity with stated monthly output of 65,000 tonnes and annual capacity of 770,000 tonnes, figures that buyers should verify against published financial filings or independent industry databases. The Hi-Tec Industrial Zone address suggests a registered office or sales function; confirmation of actual rolling-mill location and whether this entity is the listed parent or a subsidiary should be sought during due diligence.

The supplier emphasises research and development strength and patent holdings, though no specific patent numbers or R&D accreditations are provided in the source. The product portfolio centres on 3003 household foil, container foil, packaging foil, and electronic foil. No information on year of establishment, employee count, specific quality certifications, or named clients is present in the source material. The zero response rate and zero average response hours indicate no recent quotation activity through the platform, so buyers should establish direct communication via the supplier's corporate channels and request audited production capacity figures and current order-book status before committing to volume purchases.
