AA8011 O 0.006MM Composite Aluminum Foil for Cable Shielding

1. Product Overview

AA8011 O 0.006MM Composite Aluminum Foil is a high-precision, ultra-thin composite shielding material specially developed for cable electromagnetic shielding and insulation protection. Adopting premium 8011 aluminum alloy with O temper (fully soft annealed) and advanced multi-layer composite lamination technology, the product features ultra-thin thickness of 0.006mm, excellent flexibility, uniform texture and zero pinhole rate, perfectly adapting to high-speed cable wrapping and winding processes. Combined with superior electrical conductivity and electromagnetic interference resistance, it can effectively isolate external EMI/RFI interference, stabilize internal signal transmission, and serve as an ideal shielding and moisture-proof barrier for various communication, data and power cables.

The composite structure integrates aluminum foil and polymer materials (PET/PE/BOPP optional), which complements the metal shielding performance and polymer mechanical protection performance. It solves the problems of easy breakage, poor toughness and unstable shielding effect of traditional ultra-thin aluminum foil, and meets the high-standard shielding requirements of high-frequency, high-speed and long-distance cable transmission scenarios.

3. Core Product Advantages

Ultra-high Shielding Performance, Stable Signal Transmission

Made of standard AA8011 alloy with uniform metal density and ultra-high conductivity, the product delivers excellent electromagnetic shielding ability, effectively isolating external electromagnetic interference and crosstalk between internal cable cores. With a shielding effectiveness of up to 90dB, it completely eliminates signal attenuation, distortion and noise interference, ensuring high-speed, stable and lossless transmission of cable signals, which is especially suitable for high-frequency communication and precision signal cables.

Ultra-thin & Super Flexible, Easy Processing

The 0.006mm ultra-thin design greatly reduces the overall weight and outer diameter of the cable, helping customers realize cable lightweight and miniaturization upgrade. O temper full annealing process endows the foil with super ductility and bending resistance, no cracking, no peeling during high-speed wrapping, twisting and bending of cables. The composite layer enhances structural toughness, solving the fragility problem of single ultra-thin aluminum foil and improving production yield.

Zero Pinhole & Superior Barrier Property

Adopting precision rolling and dust-free composite production process, the product achieves zero pinhole in the whole sheet, completely avoiding signal leakage and moisture penetration caused by tiny holes. The composite polymer layer forms a dense waterproof and moisture-proof barrier, effectively protecting the cable inner core from moisture, oxidation and corrosion, greatly extending the service life of cables in humid and harsh environments.

Wide Temperature Adaptability & Strong Durability

It maintains stable physical and shielding performance in the temperature range of -40℃ to 120℃, without brittle fracture or performance degradation. It has excellent oxidation resistance and environmental aging resistance, adapting to long-term outdoor exposure, buried laying and indoor high-temperature working environments, with long-term stable service performance and low later maintenance cost.

Customizable & High Compatibility

Support single-sided/double-sided composite, different polymer material matching and arbitrary width slitting. It is highly compatible with all types of cable automated wrapping machines, with high fitting degree and fast production speed, which can effectively improve cable production efficiency and reduce production costs for manufacturers.
