In modern cable manufacturing, effective electromagnetic shielding combined with lightweight moisture barrier performance is essential for maintaining signal integrity and long-term reliability. Aluminum Tape for Cable — also known as aluminum foil tape or plain aluminum shielding tape — is a high-purity, precision-slit aluminum foil engineered specifically for the cable industry.
Produced from premium soft-annealed aluminum alloys (1070, 1060, 1050, 1145, 1235, 8011), this bright silver tape serves as both a standalone shielding/wrapping layer and the critical base substrate for copolymer coated aluminum tapes and AL+PET laminates.
Its excellent electrical conductivity, superior formability, and consistent dimensional accuracy make it the preferred material for longitudinal wrapping, helical wrapping, and EMI/RFI shielding in communication cables, power cables, coaxial cables, data cables, and specialty control cables.
As a specialist B2B cable materials supplier with decades of global project experience, we position aluminum tape as a cost-effective, lightweight technical solution that delivers reliable performance while optimizing production efficiency and overall cable economics.
Composition & Engineered Manufacturing Process
Aluminum Tape for Cable is manufactured from high-quality aluminum coils that undergo precise slitting to exact widths.
Key characteristics include:
- Base alloys: 1070, 1060, 1050, 1145, 1235, or 8011 series — chosen for high purity (≥99.1% aluminum), excellent conductivity, and corrosion resistance.
- Temper: Soft-annealed (O temper) for maximum flexibility and formability; also available in H22.
- Surface finish: Bright silver appearance with outstanding UV stability and weather resistance.
- Edge quality: Precision-slit with tight tolerances for clean edges, minimal burrs, and uniform thickness — enabling seamless integration into high-speed longitudinal or helical wrapping lines.
When used as the base for copolymer coated aluminum tape or AL+PET laminates, the aluminum foil provides the primary conductive shielding layer while the coating enhances adhesion and moisture barrier properties. Single-sided (AL+PET) and double-sided aluminum foil tape constructions are both supported.
Key Technical Advantages & Performance Benefits
Superior Electromagnetic Shielding & Conductivity
Aluminum offers approximately 61% IACS conductivity with near-100% optical coverage when applied longitudinally or with overlap. It effectively attenuates high-frequency EMI/RFI interference, making it ideal for data transmission and power cables where signal integrity is critical.
Excellent Formability & Processing Efficiency
High elongation combined with soft-annealed temper allows smooth wrapping without cracking or wrinkling — even at high production speeds. The tape conforms perfectly to cable geometry, ensuring uniform coverage and minimal waste.
Lightweight Moisture Barrier & Environmental Resistance
Aluminum naturally forms a protective oxide layer that provides outstanding resistance to moisture, humidity, chemicals, solvents, and UV exposure. When combined with adhesive or copolymer systems, it delivers flame-retardant and water-resistant properties while remaining significantly lighter than copper alternatives.
Strong Adhesion & Clean Application
Precision-slit edges and high-purity surface ensure strong bonding (no residue) and easy tearing/application during manufacturing. The bright silver finish also aids visual quality inspection on the production line.
Cost-Effective & Sustainable
Aluminum tape offers lower material cost and reduced cable weight compared to copper foil or braided shields, supporting overall project economics and ESG goals (100% recyclable).
Primary Applications in Cable Systems
Aluminum Tape for Cable is widely specified for:
- Base substrate for copolymer coated aluminum tape and AL+PET laminates in MV/HV power cables and communication cables.
- Longitudinal and helical wrapping as a shielding layer in medium- and high-voltage power cables.
- EMI/RFI shielding in coaxial, data, telecommunication, control, and instrumentation cables.
- Moisture barrier in underground, aerial, direct-buried, and specialty cable designs requiring lightweight protection.
It is particularly effective in fixed installations and high-frequency applications where near-100% coverage and low transfer impedance are required. Many manufacturers combine it with drain wires or braided shields for hybrid shielding solutions.

FAQ
What is the difference between plain aluminum tape and AL+PET / copolymer coated aluminum tape?
Plain aluminum tape is the base foil used for shielding and wrapping. AL+PET and copolymer-coated versions add a polyester film layer (single or double sided) for improved mechanical strength, adhesion, and moisture barrier performance.
Is aluminum tape suitable for high-frequency EMI shielding?
Yes. When applied with proper overlap or longitudinally, it provides excellent high-frequency shielding and is widely used in data, coaxial, and telecommunication cables.
Can you supply double-sided aluminum foil tape?
Yes. We support both single-sided (AL+PET) and double-sided aluminum foil tape constructions, as well as heat-sealable and self-adhesive variants.
What alloys and tempers are available?
Standard alloys include 1070, 1060, 1050, 1145, 1235, and 8011 in O (soft annealed) and H22 tempers. Other alloys and tempers available on request.
What is the typical conductivity?
≥59% IACS, with excellent consistency across batches.
