Copper Foil is a thin sheet of copper metal, usually produced in thicknesses between 0.0005 inch (0.013 mm) and 0.02 inch (0.51 mm). It consists of 99.9% or higher purity copper with specific conductivity greater than 100 IACS. Copper foil is commonly used for electrical applications, such as shielding, heat dissipation, surface finishing and RFI/EMI suppression due to its great electrical conductivity properties and low cost compared to other metals like silver or gold foils.

Copper foil is a versatile material widely used for a variety of applications. It offers excellent electrical and thermal conductivity, corrosion resistance, malleability and ductility. Due to its malleability, it can be easily formed to meet specific requirements in many industries, such as electronics, construction and engineering. Copper foil is also commonly used to produce printed circuit boards (PCBs). In addition to all these benefits, copper foil boasts an attractive golden hue that adds aesthetic value to its uses.
