Copper tape is a versatile and widely used material. It's a type of electrical tape that's wrapped in a thin layer of copper.
Copper tape is often used for its electrical conductivity, which makes it a great choice for projects that require a low-voltage connection. This is because copper is an excellent conductor of electricity.
You can use copper tape to create a simple circuit or to repair a broken wire. For example, if you're building a DIY electronics project and need to connect two components, copper tape can be a quick and easy solution.
Copper tape is also a great choice for thermal management, as it can help to dissipate heat away from electronic components. This is especially useful in applications where heat buildup can be a problem, such as in high-performance computers or audio equipment.

This copper adhesive tape has a variety of applications, including laminating to painted surfaces, metals, and various plastic films.
The tape features good chemical resistance and has moderate tack and high shear strength.
The adhesive thickness is a crucial aspect of copper tape, and in this case, it's 2 Mils.
The tape is available in different widths, including 3″, 4″, and 24″.
Copper tape is designed to be highly conductive, with a volume resistivity of 0.06Ω·m and an observed resistance of 5m Ω.
Here's a summary of the key features of copper tape:
The tape's holding power is also impressive, with a minimum of 600 minutes at room temperature, as measured by the PSTC 107 Mod./178° test.

How to Use Copper Tape
Copper tape comes in two forms: with conductive adhesive and with non-conductive adhesive. The latter is more common, often found in the gardening section of local hardware stores, where it's used to keep snails and slugs out of gardens.
You can make electrical connections with conductive adhesive tape by simply taping one copper tape to another, but these connections are less durable over time. Non-conductive adhesive tape, on the other hand, requires soldering or folding the ends to create reliable connections.
To make curves with copper tape, start by sticking the end of the tape down to create an anchor, then crease the tape slightly to turn and flatten the crease. This process can be repeated to create a smooth curve.
Here are some places where you can buy copper tape:
- Home improvement stores like Home Depot or Ace Hardware
- Craft stores
- Sparkfun
- Adafruit
- Digikey
- Less EMF
- Conducti
Getting Started
Copper foil tape comes in two forms: with conductive adhesive and with non-conductive adhesive.
You can find copper tape with non-conductive adhesive at your local hardware store in the gardening section, where it's used to keep snails and slugs out of gardens.
Conductive adhesive tape is only available online, so you'll need to order it if you want it.
Non-conductive adhesive tape is more common and can be used to make electrical connections, but you'll need to solder the tapes together or fold the ends to create a reliable connection.
To make curves with copper tape, start by sticking the end of the tape down to create an anchor.
You can then crease the tape slightly to turn and flatten the crease, and continue this process to create a smooth curve.
The more you turn at each step, the tighter the curve will be, and the thinner the tape, the sharper the turn will be.
You can find copper tape and other conductive foils at a variety of online retailers, including Sparkfun, Adafruit, and Digikey.
Here are some online retailers where you can find copper tape:
- Sparkfun has copper tape with non-conductive adhesive
- Adafruit has copper tape with semi-conductive adhesive in 6mm and 25mm wide rolls
- Digikey has copper tape with conductive adhesive
- Less EMF has a wide variety of materials, including conductive threads, fabric tapes, and paints
- Conducti specializes in conductive threads and conductive metal and fabric tapes specifically for circuit crafting
Uses
Copper tape is a versatile tool that can be used in a wide range of applications and environments.
Electro-magnetic shielding is one of the most common uses of copper tape, as it can effectively block electromagnetic radiation and protect electronic devices from interference.
Professionals and hobbyists alike use copper tape for DIY crafting projects, such as making decorative items or repairing electronics.
It's also used as a slug repellent, as slugs don't like to cross over the copper tape, making it a great solution for gardeners.
Copper tape is easy to work with, making it a great option for those who are new to crafting or electronics.
Crafting with Copper Tape
You can use copper tape to add a shiny border to artwork, creating a beautiful and eye-catching effect.
Copper tape comes in different thicknesses, making it easy to select a tape width that suits the size of your project.
To use copper tape for stained glass, simply peel the tape and place it on the edge of the first piece of glass, pressing it firmly down around the edge of the shape.

Paper Circuits
Paper circuits are low-voltage electrical circuits that can easily be created using common materials.
You can use copper tape to provide the current from one part of the circuit to another, making it a great addition to your circuit design.
Copper tape is ideal for conducting low levels of electricity around the circuit, which is perfect for DIY or domestic projects.
To create a paper circuit, simply use copper tape to connect different components, such as lights or sensors, to create a functional circuit.
Copper tape is easy to use and can be applied to paper or other surfaces to create a conductive path.
With copper tape, you can create a wide range of paper circuit designs, from simple to complex, making it a great tool for learning about circuits and electrical conductivity.
By using copper tape in your paper circuits, you can add a new level of creativity and functionality to your DIY projects.
Plant Pots
Copper tape is a versatile material that can be used in various creative ways, including protecting your plant pots from unwanted pests. Slugs can ruin plants if left unchecked, which is why many gardeners choose to use copper tape to deter them.
Copper tape works by acting as a barrier, and gardeners simply stick a strip of it around the plant pot, just below the rim. The effectiveness of this method is still being discussed, but it's a popular choice among gardeners as a more environmentally-friendly alternative to other slug and snail repellents.
Working with Copper Tape
Working with copper tape can be a fun and creative process. Copper tape can be used to create decorative wall art by adapting and shaping it to suit various patterns and designs.
You can use copper tape for soldering, a practice that's particularly useful with non-conductive tape types. Soldering involves creating a strong join between separate strips of copper tape to create a reliable path for electrical connection.
Soldering is a relatively straightforward process, but safety is essential, so make sure you're fully prepared and using the correct equipment before using soldering equipment.
Properties
Copper tape is designed to conduct electricity on both sides of the tape, making it easy to create electrical connections by taping multiple lengths together.
The strength of this electrical connection can fade over time, so alternative methods of connection may be needed to ensure continued conductivity.
A single continuous strip of copper foil tape is always a more effective conductor than multiple strips joined together.
The conductive adhesive in copper tape is not designed to carry high levels of current.
