Abstract: A method of making a rolled aluminum product comprises sawing an aluminum ingot so that the ingot is separated into at least two separate aluminum slabs and rolling at least one of the slabs unclad and unbrazed. In some embodiments, the ingot is sawn horizontally, across its face, as so that, the slabs are equal in length to the ingot. In some embodiments, at least one of the slabs is rolled to form a one of a plate, sheet or foil. The rolling can be hot rolling or cold rolling. Some embodiments further comprise scalping the aluminum ingot. In some embodiments, the sawing of the ingot eliminates or reduces the need to scalp the aluminum ingot and scalping is not performed. Some embodiments further comprise sawing curved edges off the aluminum slabs.

Abstract: A fastener adapted to pass through aligned holes through workpieces is disclosed. The fastener includes a pin member having a transition portion wherein the diameter of the transition portion decreases radially as it extends from the smooth cylindrical shank portion to the threaded portion. The fastener may also comprise a sleeve member and a clamping means. The clamping means includes a collar, a nut, or any other possible clamping means. In exemplary embodiments, the workpieces can be formed with a plurality of materials, the materials including composite, metallic, or composite/metallic structures, any combination thereof. In particular embodiments, the fastener has interference capability of 0.0005 to 0.0100 inches in composite structures without risk of composite delamination or damage. As a result of the fastener interference, gaps between the fastener and the structure are eliminated thereby providing good electrical conductivity between components. As a result, the potential for electrical sparks is reduced, providing a safer fastener for use with aerospace applications.
