Abstract: A swage collar including a shank having a first end, a second end opposite the first end, and an outside diameter, a flange extending circumferentially from the first end of the shank and having a outer diameter, and a scalloped shoulder formed at a location where the first end of the shank transitions to the flange. When the swage collar is swaged, the shoulder is deformed from an undeformed state to a deformed state such that the shoulder is blended with the outside diameter of the shank and the outer diameter of the flange. When the shoulder is in its deformed state, it includes multiple curved portions each having a radius of curvature that visually indicates all around the outside diameter of the collar a complete swage of the collar. Knurling located on the outside diameter of the shank and proximate to the second end is deformable and provides a visual indication of the application of an installation tool.

Abstract: The aluminum alloy product of an embodiment of the present invention includes a pair of outer regions and an inner region positioned between the outer regions. A first concentration of eutectic forming alloying elements in the inner region is less than a second concentration of eutectic forming alloying elements in each of the outer regions. Further, the aluminum alloy product has a delta r value of 0 to 0.10. The delta r value is calculated as follows: Absolute Value [(r_L+r_LT−2*r_45)/2] and the r_L is an r value in a longitudinal direction of the aluminum alloy product, the r_LT is an r value in a transverse direction of the aluminum alloy product, and the r_45 is an r value in a 45 degree direction of the aluminum alloy product.

Abstract: The present application discloses wrought 2xxx Al—Li alloy products that are work insensitive. The wrought aluminum alloy products generally include from about 2.75 wt. % to about 5.0 wt. % Cu, from about 0.2 wt. % to about 0.8 wt. % Mg, where the ratio of copper-to-magnesium ratio (Cu/Mg) in the aluminum alloy is in the range of from about 6.1 to about 17, from about 0.1 wt. % to 1.10 wt. % Li, from about 0.3 wt. % to about 2.0 wt. % Ag, from 0.50 wt. % to about 1.5 wt. % Zn, up to about 1.0 wt. % Mn, the balance being aluminum, optional incidental elements, and impurities. The wrought aluminum alloy products may realize a low strength differential and in a short aging time due to their work insensitive nature.

Abstract: An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a steel rivet and a spot welding machine. The rivet and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the rivet to penetrate the aluminum and weld to the steel layer. The fastener may be used to join stacks with several layers of different materials and may be used to apply a threaded socket or stud made from steel or titanium to an aluminum or magnesium alloy structure. Layers of non-conductive materials like plastic and ceramics may also be affixed to a conductive layer using the fastener made from a compatible material that extends through a pilot hole.
