Abstract
A bi-metallic component including a tubular stud member extending from an open first end to an open second end, and a cast member cast around the open second end of the tubular stud member is provided. The cast member is formed from first material, such as an aluminum alloy; and the tubular stud member is formed from a second material, such as steel. The tubular stub member has an interior surface which sealingly receives a removable core member for preventing molten first material from flowing through the stub member between the open ends thereof during casting of the cast member around the second end. The bi-metallic component can be used in a variety of automotive applications, for example in a cradle, frame, twist axle, control arm, door pillar, instrument panel support, or bumper assembly.
