Copper foils are thin sheets or strips of high-purity copper, widely used across electrical, electronic, and industrial applications due to their excellent electrical conductivity, thermal conductivity, flexibility, and malleability.

At Alcutrans, copper foils are supplied in a wide range of thicknesses—from micron-level foils to heavier gauges—to meet diverse application requirements.

Material Properties & Design

Copper foils are highly flexible and can be easily bent, shaped, or formed without compromising conductivity. Their malleability allows seamless integration into compact and complex designs.

To suit specific applications, copper foils can be surface-treated or coated to enhance adhesion, oxidation resistance, and compatibility with bonding or lamination processes.

Certain grades feature single-side treated electro-deposited surfaces, offering improved adhesion and enhanced performance under high-temperature stretching and thermal cycling conditions.
