The present invention relates to a contact element for an electrical connection, and to a circuit arrangement having at least one said contact element. A contact element for an electrical connection may include a first contact region of a first copper material for electrically connecting to a first circuit component and a second contact region of a second copper material for electrically connecting to a second circuit component. The first contact region and the second contact region each have a different material hardness, and the two contact regions are interconnected by a materially bonded connection.
