ABSTRACT:
A method of connecting an aluminum part with a steel part using a friction welding technique. The aluminum part is heat treated such as T6 treatment to raise its hardness. After that, the aluminum part is friction welded to the steel part. The steel part may also be heat treated to lower its hardness instead of or in addition to hardening of the aluminum part. A third part which has an intermediate hardness may be placed between the aluminum part and the steel part, and the aluminum part may be coupled with the steel part via the third part.
