Cu-Al – Copper-aluminum composite materials

Cu-Al is a cold-rolled clad composite material that combines the very high electrical conductivity of copper with the lower weight and material cost of aluminum.

Cu-Al composite materials, also known as copper-aluminum composite materials, are already used in various industries. In the electrical industry, they are used for the production of transformers and electric motors, for example. Cu-Al composite materials are also used in energy generation, such as in the production of generators and turbines. Furthermore, they are also used in the automotive industry, for example for electrical contacts or to improve heat dissipation.
