Conductive Aluminium Tape: A Versatile Solution for EMI Shielding and Electrical Applications

Conductive aluminium tape has become an essential component in modern electronic assembly and electromagnetic interference (EMI) shielding. Its ability to combine the conductive properties of aluminum with strong adhesive backing makes it ideal for a range of industrial, commercial, and household applications. At Handa Shielding, we manufacture and supply high-quality conductive aluminium tapes designed to deliver superior performance in demanding environments.

In this article, we’ll explore what conductive aluminium tape is, how it works, its types, applications, technical specifications, and why Handa Shielding is a trusted partner for your EMI shielding needs.

What Is Conductive Aluminium Tape?

Conductive aluminium tape, sometimes called aluminum foil tape, is a pressure-sensitive adhesive tape composed of a thin layer of aluminium foil combined with an electrically conductive adhesive. This unique construction allows the tape to perform both as a shielding material and as a conductive path for grounding and EMI protection.

The conductive adhesive ensures electrical continuity through the bonded surfaces, making the tape suitable for wrapping cables, sealing enclosures, and connecting grounding points in EMI/RFI shielding systems.

Key Features of Conductive Aluminium Tape

Here are the core properties that make conductive aluminium tape so valuable in EMI shielding and electrical applications:

• Excellent electrical conductivity on both the foil and adhesive surface
• High thermal conductivity, ideal for heat dissipation
• Strong adhesion to metals, plastics, and other materials
• Corrosion resistance with optional acrylic or solvent-based adhesive
• Flame-retardant and chemically stable under extreme conditions
• Lightweight and flexible, allowing for easy installation
• Die-cuttable into custom shapes or widths for specific projects

These features allow engineers and manufacturers to implement effective EMI/RFI shielding without the need for heavy or complex materials.

Common Applications of Conductive Aluminium Tape

Conductive aluminium tape serves a wide range of industries, from electronics and telecommunications to aerospace and automotive systems. Below are its most common applications:

1. Electromagnetic Interference (EMI) and Radio-Frequency Interference (RFI) Shielding

One of the most common uses is EMI/RFI shielding in electronic enclosures. The tape blocks or redirects electromagnetic waves to prevent signal degradation or malfunction in sensitive devices.

2. Cable Wrapping and Harness Protection

Aluminium tape is used to wrap wire harnesses and shielded cables to reduce electromagnetic noise and ensure signal integrity.

3. Electrical Grounding

Because of its conductive adhesive, the tape is excellent for providing electrical grounding paths between different components or to a chassis.

4. Printed Circuit Board (PCB) Shielding

In circuit assembly, conductive aluminium tape can be applied to PCBs to add an extra layer of EMI protection in critical zones.

5. HVAC Duct Sealing

In HVAC systems, aluminium tape seals joints in metal ducts, helping control airflow, temperature, and sound leakage. In some cases, conductive versions are used when electronic controls are involved.

6. Automotive Electronics

Used in modern vehicles to shield wiring and control modules from interference in electric and hybrid systems.

7. Aerospace and Defense Applications

Lightweight and highly durable, conductive foil tape is ideal for aircraft and defense systems requiring EMI shielding under extreme environmental conditions.

Installation and Usage Tips

To get the best performance from conductive aluminium tape, consider the following:

1. Clean the surface thoroughly before application to remove dust, oil, and oxidation.
2. Use a roller or squeegee to apply even pressure and ensure full contact with the adhesive.
3. Avoid stretching the tape during installation, as it can weaken the foil layer.
4. Overlap tape ends slightly to maintain a continuous conductive path.
5. Store rolls in a dry and cool environment to preserve adhesive quality.

FAQs About Conductive Aluminium Tape

Q1: Can aluminium tape be used as a ground?

Yes, if the tape has a conductive adhesive (like Handa Shielding’s products), it can be used for grounding in low-current or static-dissipative applications.

Q2: Is all aluminium tape conductive?

No. Some foil tapes use non-conductive adhesives. Always choose “conductive aluminium tape” with specifications that include electrical conductivity across the adhesive.

Q3: What’s the difference between copper tape and aluminium tape?

Copper has higher conductivity than aluminium but is more expensive. Aluminium tape is cost-effective and sufficient for most EMI shielding applications.

Q4: Does Handa Shielding offer custom tape widths?

Yes. We provide slitting and die-cut services to deliver tape in any width or pre-cut shape you require.
