ABSTRACT:
A wheel for a motor vehicle comprises a wheel spider with hollow spokes formed from a first material and a rim formed from a second material. The wheel spider is connected to the rim by way of friction welding. The wheel spider may be formed by casting and the rim may be formed by casting or forging and may be further formed by rolling. The wheel spider and the rim may be selected from the group consisting of aluminum, aluminum alloy, magnesium, magnesium alloy, titanium or titanium alloy. A process for making the vehicle wheel by forming the wheel spider from a first material and the rim from a second material and connecting the wheel spider with the rim by friction welding.
