An arrangement for electrically conductively connecting a cup shaped copper contact part to an electrical conductor that is made of a plurality of individual wires containing aluminum. The arrangement has a cup-shaped contact part, which includes a bottom and a cylindrical sleeve integrally connected to and projecting away from the bottom with tight contact of the sleeve to the conductor. The cup-shaped contact part is configured to be pushed onto the conductor until the end face of the conductor rests against the bottom of the contact part. At least one rotating tool is configured to be removably placed with sustained pressure, subsequently to the cup-shaped contact part, until the material of the conductor is softened due to the increased temperature of the material of the conductor due to friction to such an extent that it integrally connects to the contact part.

A cast part includes a metallic functional region. The functional region extends in a first direction from a first side to a second side of the cast part. The cast part has a surrounding region at least partially surrounding the functional region. The functional region is shaped by a friction-based process. Further disclosed is a piece of equipment, such as an electrical machine which includes a further component and a device for securing the further component against twisting. The device has a connection between the functional region of the cast part and the further component.
