Abstract: A method for producing a device for measuring current intensities, including: providing a resistor arrangement having connection elements and a resistor element arranged therebetween in a current flow direction. The resistor element and the connection elements consist of different electrically conductive materials; forming a contact pin from the material of at least one connection element; positioning a printed circuit board with a conductor track and a passage bore on the resistor arrangement such that the contact pin projects through the passage bore and has on the side of the printed circuit board facing away from the resistor arrangement a protrusion; laterally widening the contact pin in the region of the protrusion by deforming the material such that the printed circuit board is mechanically fixed to the resistor arrangement; and producing an electrically conductive connection between the contact pin and the conductor track of the printed circuit board.

Abstract: The invention relates to a sliding element consisting of a copper-zinc alloy containing the following components (in % by weight): 60.0 to 64.0% Cu, 0.2 to 0.5% Si, 0.6 to 1.2% Fe, optionally also up to a maximum 1.5% Sn, optionally also up to a maximum 0.25% Pb, optionally also up to a maximum 0.08% P, the remainder being Zn and unavoidable impurities. The copper-zinc alloy has a grain structure consisting of an α- and β-phase with a volume content of the α-Phase of at least 90%, and iron silicides are embedded in the grain structure.
