Provided herein are new aluminum alloy products and methods of making these alloys. The aluminum alloy products are age-hardenable, display high strength and formability, and allow for the use of recycled scrap. The aluminum alloys can serve as the core in a clad aluminum alloy product. The alloy products can be used in a variety of applications, including automotive, transportation, and electronics applications.

A thin, cured gel gasket is disclosed, including methods of making the thin gel gasket and the use of the thin gel gasket in an aircraft joint. In one embodiment, the thin gel gasket has no skeleton or other structure and is comprised of only a cured polyurethane gel and has a thickness of less than about 12 mill. It is manufactured using a release film that is adapted in a number of ways to make release from the gel prior to use easier. In one method of making and using the thin gel gasket. it is applied to a joint which is subject to compression, in one embodiment, a lap joint of an aircraft fuselage.
