The invention relates to a steel and aluminum combined instrument panel cross beam which comprises an aluminum pipe beam, the aluminum pipe beam is of a tubular structure made of aluminum materials, the middle of the aluminum pipe beam is bent downwards to form a U shape, an aluminum host installation support is arranged below the middle of the aluminum pipe beam and connected with the aluminum pipe beam in an arc welding mode, and the aluminum host installation support is connected with the aluminum pipe beam in an arc welding mode. The left side of the aluminum host installation support is welded with an aluminum left lower guard board installation support, the left end and the right end of the aluminum tubular beam are respectively provided with a steel instrument board installation support, the front portion of the left side of the aluminum tubular beam is provided with a steel front wall connection support, and the rear portion of the left side of the aluminum tubular beam is provided with a steel steering column installation support. An aluminum glove box installation support is installed on the lower portion of the right side of the aluminum pipe beam and used for installing an interior glove box, and a steel air bag frame installation support is installed on the front portion of the right side of the aluminum pipe beam. While enough strength, rigidity, modality and safe collision requirements are guaranteed, the self weight is reduced to the maximum extent, and meanwhile compared with a common steel cross beam, the cost is slightly increased.
