Why do aluminum extrusions sometimes have small radius …
2003年1月19日 · I have seen aluminum extruded profiles that have either a series of small radius grooves or radius ribs. Often they are symmetrical, but I have seen cases where they appear somewhat random in the design.
Rib-Structures on A5083 Aluminum Alloy Sheet Generated
2017年1月1日 · This paper describes a new forming technology, friction-stir forming (FSF), to generate a rib structure on an aluminum alloy plate. The proposed process is as follows. The authors put a 3mm-thick A5083 aluminum alloy plate on a …
A comparative study on deformation mechanisms, microstructures …
2021年9月1日 · Wide thin-ribbed aluminium profiles were manufactured by sideways and forward extrusion at the same condition. Deformation mechanisms, resulting microstructures and mechanical properties for the two processes were compared. Sideways extrusion requires a lower extrusion force but results in higher effective strains in the profile rib.

Curvature, microstructure and mechanical property of an …
2024年12月18日 · In this study, aluminium profiles with a Z-shape cross-section were produced through a novel sideways extrusion method involving discontinuously increased extrusion speeds (0.05, 0.1, 0.5 and 1 mm/s). The weld quality, and the microstructural and mechanical properties of the profile were examined experimentally.

Aluminum Extrusion Design Guidelines and Manual | AEC
There are key factors to consider when designing aluminum extrusions, including cross section size and wt/ft. Download our extrusion design manual for design tips, applications & more.
Many of aluminum tubes, used as structural section are made by extrusion (Fig.1(a)). Most of the aluminum tubes with complex section shape are manufactured by extrusion. Especially, the tubes that have internal rib are used as car parts, such as structural components, radiators and impact absorbers (Fig.1(b)) [1].
A Low Force Extrusion Technique for Producing Wide-Thin Aluminium …
2023年8月23日 · This research introduces a new extrusion method, which has multiple extrusion containers, for producing wide-thin aluminium components with significant reduction of extrusion ratios and thus reducing extrusion forces.
Aluminum alloys are well adapted to cold (impact) extrusion. The lower-strength, more ductile alloys, such as 1100 and 3003, are the easiest to extrude. When higher mechanical properties are required in the final product, heat treatable grades are used.
