Aluminum Extrusion Applications

“The future cannot be predicted, but futures can be invented.”

— Denis Gabor, nobelist and author of Inventing the Future (1963)

Editor’s Note: As aluminum extrusion applications extend to most business areas, especially for B&C, transportation, industrial, consumer, and defense, it is no wonder that inventions utilizing aluminum extrusions to meet present and future needs of these industries are so varied and creative. Case in point is the selection of patents presented in this issue, all patented in the U.S. within the past year alone and representing a broad assignee base of international companies.  These inventions make use of the light weight, special physical and mechanical properties, and sustainable features of a mix of aluminum alloys in a varied range of economical shapes in support of structures throughout the world both functionally and aesthetically. Thus, the global aluminum extrusion market size was US$87.8 billion in 2021 and is expected to grow at a compound annual growth rate of 7.5% from 2022 to 2030 ( 

In 2021, the U.S. aluminum extrusion market was US$7.3 billion, with the shapes product segment accounting for the maximum revenue share of more than 79.5% over rod & bar and pipe & tube, pointing out how the excellent formability of aluminum alloys in the extrusion process leads to customer value. 

However, like analytic geometry, market research in any field depends on assumptions, and these can lead to excellent outcomes—if they are accurate and hold up over time. Considering some of the surprise events of the past two years, particularly the COVID pandemic and Ukraine war, we have to consider the risk of future surprises (or “black swan” events), which may upset the equilibrium of manufacturing industries and affect the aluminum extrusion market—but such instances are hard to predict. Yet, as the selected patents below show and as Denis Gabor has noted, the future can be invented.

A curtainwall unit may comprise a frame including a horizontal gutter, a horizontal sill, a first vertical mullion between a first end of the horizontal gutter and a second end of the horizontal sill, and a second vertical mullion between a second end of the horizontal gutter and a second end of the horizontal sill. The horizontal gutter may include a rear channel extending across the horizontal gutter, and at least one protected horizontal channel at least partially beneath the rear channel, the rear channel having at least one opening to the at least one horizontal gutter. Each vertical mullion may include a protected vertical chamber having an opening to the at least one protected horizontal channel. The perimeter framing members of a unitized system may be designed with gaskets and male/female mating aluminum extrusions which, when fitted together, create an air and water barrier between the interior and exterior without the use of wet sealants between adjacent curtainwall units.


US11273622 — STIFFENING ELEMENTS THAT COMPRISE INTEGRAL CURRENT FLOWPATHS — The Boeing Company (USA) — A stiffening element that includes one or more integral current flowpaths may include: a first layer including carbon-fiber-reinforced thermoplastic plies; a second layer including one or more glass-fiber-reinforced thermoplastic plies; and/or a third layer including aluminum. The third layer may form an outer surface of the stiffening element. The third layer may form at least part of the one or more integral current flowpaths. A method of using a stiffening element that comprises one or more integral current flowpaths as part of a current return network for a stiffened structure may include: selecting the stiffening element that includes a first layer including carbon-fiber-reinforced thermoplastic plies, a second layer including one or more glass-fiber-reinforced thermoplastic plies, and/or a third layer including aluminum; and/or routing current from the current return network (CRN) through the one or more integral current flowpaths of the selected stiffening element. Portion of such CRNs may be fabricated, for example, with aluminum extrusions. Such aluminum extrusions may be made with non-structural-grade aluminum having relatively low resistivity values, as opposed to relatively higher resistivity values often associated with structural-grade aluminum.


— The present invention is directed extruded aluminum members which are comprised of parts that snap fit together without requiring any screws or rivets. Such members can be used in the construction of assemblies such as post and rail fences, fence panels and balustrades and the like to improve ease of manufacture and installation. A post for a fit together panel comprising at least one said post and at least one slat, the post comprising a base member and a cover member, the cover member comprising a pair of sidewalls and an interconnecting end wall, the interconnecting end wall containing a plurality of openings through which the end of a slat can pass, the sidewalls adapted for extension over the channel member, the base member comprising a base wall and opposed sidewalls, at least one sidewall comprising a clamping leg adapted for clamping engagement against the end of a said slat passing through a said opening in the cover member, and snap fitting means on the channel member and/or the cover member to enable the channel member and the cover member to be snap fitted together.


US11220299 — MODULAR LOADING PLATFORM FOR A VEHICLE — Axel Johnson International AB (Sweden) — A modular loading platform for a vehicle, comprising a frame composed of a plurality of interconnected aluminum extruded frame members, wherein the members are each provided with at least two parallel grooves extending along the members and facing away from the frame. The platform further includes a set of mounting elements having parallel protrusions which have been inserted into engagement with said parallel grooves in one of the members. The mounting elements form a structure on which additional parts of the loading platform may be mounted.
