Abstract: Provided are new high strength 6xxx aluminum alloys and methods of making aluminum sheets thereof. These aluminum sheets may be used to fabricate components which may replace steel in a variety of applications including the transportation industry. In some examples, the disclosed high strength 6xxx alloys can replace high strength steels with aluminum. In one example, steels having a yield strength below 340 MPa may be replaced with the disclosed 6xxx aluminum alloys without the need for major design modifications.
