Import 3003 Electronic Packaging Aluminum Foil — Buy in wholesale FOB from Supplier in China

3003 electronic packaging aluminum foil is an Al-Mn series alloy foil specifically manufactured for capacitor and electronic component applications, supplied by Henan Sigma Aluminum Industry Co., Ltd from Zhengzhou, China. The alloy's manganese content provides higher corrosion resistance and greater strength than 8011 or 1100 grades commonly used in general packaging. The supplier offers tempers H22 and H24, with thickness range 0.015-0.20 mm, width 30-1500 mm, and coil lengths of 2000-4000 meters. These dimensions suit precision winding operations in capacitor manufacturing where uniform thickness and freedom from pinholes are critical. The product is positioned for the Canadian market among others, with factory-direct supply claimed.

The foil's anti-rust properties stem from manganese alloying, making it suitable for environments where electronic components require long-term reliability. Internal organizational uniformity is emphasized by the supplier as a key quality attribute for electronic packaging, where inclusions or thickness variations can cause capacitor failure. Typical surface requirements for capacitor foil include bright, oil-free finish with controlled surface roughness (Ra) to ensure proper electrode adhesion. The H24 temper provides higher strength than annealed foil, maintaining dimensional stability during winding and impregnation processes. Henan Sigma highlights advanced equipment and technology in their production, though specific line details or certifications are not provided in the source material.

Primary buyers are capacitor绕线机 (winding machine) operators, capacitor OEMs, and electronics contract manufacturers serving consumer, automotive, and industrial markets. The foil serves as the dielectric substrate in electrolytic and film capacitors where it forms the anode or cathode foil. Importers should note that the supplier does not list MOQ, price, or specific lead times in the available data, requiring direct confirmation. Payment terms, Incoterms, and packaging specifications for precision foil shipment also need clarification. Buyers in North America should verify compliance with RoHS and REACH for electronic materials, and whether the supplier provides material composition declarations or IMDS entries for automotive capacitor applications.

Henan Sigma Aluminum Industry Co., Ltd is located at 2411 Building Wangding International, Shangwuwaihuan Road, Zhengzhou, China, postal code 450000. The company holds a harbor trust tier with a response rate of 0.00% and average response hours of 0, indicating no response data is available through the platform. The supplier positions itself as a professional manufacturer of electronic packaging aluminum foil 3003 for capacitors, with emphasis on factory-direct pricing. The listing mentions Canada as a main market, suggesting established export experience to North America.

The provided profile does not include year of establishment, production capacity, number of employees, factory floor area, revenue figures, or specific client names. No quality management certifications such as ISO 9001 or IATF 16949 are mentioned. The company name includes 'Sigma' and references 'Mingtai Aluminum' in the application description, which may indicate a trading relationship or possible confusion with another entity, buyers should clarify this directly. The advanced equipment claim is not substantiated with specific line names, manufacturer, or technology generation. Importers should request business license, export license, and factory audit reports before first orders.
