→6.2 Contact Materials and Design of Contact Components
|Brushes: Au alloys, AgPd, AgPdCu; Slip rings: Au alloys, Ag alloys (Rh); For higher currents: Ag/C brushes against Ag slip rings
|Brush wires, stamped brushes; solid, clad, or electroplated slip rings, Ag/C formed parts
|-
|Sliding contacts in miniature motors
|Very high frictional wear resistance, sure contacting even at very low contact forces
|Ag and Au alloys, Pd alloys, Au multi component alloys
|Brushes from flat rolled wire or stamped; collector hard gold electroplated or clad, or made from miniature profile segments
