The main component of copper foils, which are frequently categorised under grades like C11000 (electrolytic tough pitch) or C12200 (phosphor-deoxidized copper), is ≥99.9% pure copper. These foils have exceptional corrosion resistance, high thermal conductivity, and excellent electrical conductivity (up to 100% IACS). They usually have an elongation of 30–45%, a yield strength of 70–250 MPa, and a tensile strength of 210–370 MPa. Copper foils are perfect for use in electrical components and heat transfer systems because they are extremely ductile, malleable, and appropriate for complex fabrication processes.
