C1100 copper foil has good electrical conductivity, heat conduction, corrosion resistance and processing properties. It can be welded and brazed.
The impurities and trace amount of oxygen only have very few effect on electrical and thermal conductivity.
Copper foil is a thin sheet of copper that can be used for a variety of purposes such as decorative accents, electrical conductivity, and shielding. It is typically sold in rolls and can be easily cut or shaped to fit specific applications. Copperfoil is often used in stained glass work as a way of leading the glass pieces together.
It is also commonly used in electronics as it is an excellent conductor of electricity and can help to prevent electromagnetic interference. Copperfoil is available in a range of thicknesses and finishes to suit different needs.
