Bimetal is a permanent object composed of two various metals, which have different chemical and physical properties. Cupal is classed as bimetal. It is a composite of copper and aluminum. It occurs in form of bars and wires. However, it forms mainly rolled products – sheets, plates, strips, belts.

Concerning the rolled products offered, the chemical composition of copper layer corresponds to CuETP grade and that of aluminum layer to EN-AW1050 grade. The ratio of copper-aluminum is 1:1.

Cupal is mostly used in electrical industry, for construction of cable lines and radiators, and for joining of copper and aluminum wires.
