The automobile component may include outer panel sections, high form inner sections, reinforcement sections, crash sections, large flat panel sections, and high strength sections and, when tested in a static axial crush test, a peak load of the automobile component increases at least 20% when compared to alloy 6014 in the T6 temper.

Abstract: A method to cast-in-place thermal barriers to create a hollow tubular extrusion is disclosed herein. Clips, configured to engage and lock with a first and a second extrusion profile, maintain a pocket with precise tolerances into which liquid polyurethane is poured. The clips easily engage in a manner to form a hollow tubular extrusion assembly. Once the assembly is made, it becomes very difficult to take the assembly apart. This feature allows the first and the second extrusion profiles to be cut to length or handled without the potential of the assembly coming apart prior to pouring the liquid polyurethane. Once the polyurethane cures, there is no need to remove the clips because the clips are made from a very low conductance material, and the clips can remain as part of the finished product thus saving the expense of removing and discarding the part.

The brake drum and wheel mounting tool comprises an elongated body and a threaded bore. The elongated body is dimensioned to be received through a stud hole of a wheel. The elongated body has first end and a second end. The first end of the body is dimensioned to apply pressure to a brake drum when the body is threaded on a wheel stud. The second end of the body is tapered and dimensioned to accept a socket.

Abstract: A mounting assembly for connecting a light shelf to a structure in cantilever fashion. A pair of receiver units attach to the structure and each has a pair of brackets with a slot there between. A recess is formed on an upper interior surface of the upper bracket. The lower bracket has an abutment support surface distal to the structure. A pair of inserter units attach to opposite sides of the shelf, each having an insertion leg and an abutment support. The insertion leg inserts into the recess of a corresponding receiver when the abutment support rests on the abutment surface. The weight of the shelf pulls the abutment support into engagement with the abutment surface and pushes the insertion leg into engagement with the recess, holding the shelf horizontally.

Abstract: New 6xxx aluminum alloy bodies and methods of producing the same are disclosed. The new 6xxx aluminum alloy bodies may be produced by preparing the aluminum alloy body for post-solutionizing cold work, cold working by at least 25%, and then thermally treating. The new 6xxx aluminum alloy bodies may realize improved strength and other properties.
