Steel-aluminum composite conductor rail and manufacturing method thereof

The invention relates to conductor rails for rail transit, in particular to a steel-aluminum composite conductor rail and a manufacturing method thereof. The steel-aluminum composite conductor rail comprises an aluminum base and is characterized in that a plate-shaped wear-resistant body is arranged at the upper end of the aluminum base, wear-resistant body clamp grooves are arranged in two sidesof the upper end of the aluminum base, the wear-resistant body comprises two single wear-resistant body parts, the section of each single wear-resistant body part is L-shaped, the lower end of each single wear-resistant body part bends inwardly to form a bent part, single wear-resistant body part teeth are evenly arranged at the edge of each bent part, a central-embedded-strip mounting groove is formed in the upper end of the aluminum base, a central embedded strip is arranged in the central-embedded-strip mounting groove, the two sides of the central embedded strip compresses against the lateral wall of the central-e
