The utility model discloses a nonmetal and metal composite belt pulley which comprises a belt pulley body, a belt groove is formed in the outer side face of the belt pulley body, or the outer side face of the belt pulley body is a plane, and a center hole is formed in the middle of the belt pulley body. The belt pulley body is formed by connecting a non-metal wheel disc on the outer side and a metal wheel core on the inner side. Inclined spokes are arranged on the non-metal wheel disc, and a heat dissipation air groove is formed in a cavity between every two adjacent spokes. And the spoke connects the large disc outside the non-metal wheel disc with the small disc wrapping the metal wheel core inside. According to the belt pulley, nonmetal and metal are compounded, so that the weight is effectively reduced, the metal consumption is reduced, and the cost can be greatly reduced while the self weight is reduced; in the rotating process of the belt wheel, the obliquely-arranged spokes have the air guiding effect,
