摘要： A sulfidation-resistant current-carrying member, such as a commutator, suitable for a direct-current motor in a fuel pump is provided. The current-carrying member for a direct-current motor in a fuel pump includes a commutator composed of a carbon layer having carbon as a principal component and forming a sliding surface at one end, and a metal carbon layer fixedly bound with the carbon layer at the other end and comprising 55 to 90 wt % of metal having brass as a principal component and a remaining portion having carbon as a principal component. By using brass as a primary metal component in the metal carbon layer, it is possible to achieve a commutator with superior resistance to sulfidation.
