The Many Varied Faces of Copper Foil

2016-11-01

Copper foil and sheet stocking alloys come in a wide variety of choices. Among the most popular are the 110 alloy along with the 101,102 and ED (Electro Deposited). A full range of thicknesses are also available to fit an eclectic array of applications. Stock typically starts at.0007" thick and goes up to 0.062" thick, but for those who require specific thicknesses, material up to 36" wide and as narrow as 1/4" wide can also be processed.

Using reflective foil duct wrap insulation to create a radiant barrier around your duct work is one of the easiest DIY projects you can do to improve the performance of your heating and/or cooling system. Every minute HVAC systems run without effective insulation, your ducts leak valuable energy.

Walk entire duct run and ensure all portions are wrapped. Tape and seal all seams where any pieces of insulation meet. Make sure all seams are sealed.

You have now created a radiant barrier surrounding your duct work that will reflect radiant heat, a major source of energy loss. By using spacers, an airspace has also been created that will allow the reflective foil insulation to work at its optimal level.

Therein, an experiment was conducted on graphene, a lightweight substance made of pure carbon, in which the substance was grown on copper foil. The foil was then "exposed to a chemical agent that dissolves copper." That's when an unexpected outcome occurred. Rather than the graphene protecting the copper as science has led one to believe, the chemical agent passed through, "corroding the underlying copper." Although a limit existed on the size of the molecules that were able to pass through, the substance didn't quite live up to expectations. Scientists are now left with the task of discriminating "between smaller molecules."

To make the Duct Foil Tape, slim bands of copper are joined together. Like copper foil sheeting, copper foil tape comes in varied widths. It is also available in adhesive and non-adhesive varieties. But it is copper foil tape's applications that are most eclectic. The conductivity of the product makes it ideal for the electrical and electronics fields. Typically it is used in these areas to protect delicate but vital electronic components. Crafters also frequently make use of it in their mosaic and stained glass projects.
