An Overview of Copper Aluminum Foil


Copper aluminum foil is a tape made from strips of copper and aluminum. This tape comes in varying widths, and it may be adhesive or nonadhesive. There are a wide range of uses for this tape, ranging from gardening to amateur radio operations, and this product is available from places like hardware stores, gardening stores, and electronics stores. The cost varies, depending on the width of the tape and whether or not it is adhesive.

In electronics, copper aluminum foil is valued because copper is conductive and highly reliable. This tape may be used for shielding various electronic components, or for other electronics projects. Tapes for use in electronics are often of the extra thin foil tape type, which makes them lightweight and easy to handle, although thicker tapes are also available. Electricians may keep a roll on hand for various projects, as do people who work with audio components.

Crafters also use copper aluminum foils. In stained glass and mosaic work, the foil may be used to hold elements of a design together, and it can also be used to create decorative accents in various crafts projects. Copper aluminum foil for crafting is often used with solder and a soldering iron, with the crafter soldering the ends of the tape together or bending the tape and soldering it to create a frame for a craft project. Craft stores often sell several different thicknesses of copper aluminum foil for different projects, along with other metal tapes.

Gardeners can utilize this foil for a range of garden projects, with one of the more interesting uses of copper aluminum foil in gardening being as a form of natural pest control. Slugs and snails have difficulty passing over copper, because the metal reacts with the viscous fluids they secrete, so copper aluminum foil can be used to create a very effective slug barrier around a flowerbed, tree, or flower pot.

You know, copper is famous for its tendency to develop a patina over time. While the patina is not harmful, it can interfere with the conductive properties of copper. For this reason, some copper aluminum foils are coated in substances which are designed to prevent the development of a patina, and they may be packaged in airtight or oiled packaging so that the foil does not patina while it is stored. People who are concerned about patina can rub it off with a soft cloth and a product designed for cleaning copper, although the patina will eventually reappear.
