Aluminum extrusion is the process of transforming aluminum alloy(s) into a specific cross-sectional profile. Remember using the play-doh® shape maker? Just a squeeze on the handle and the doh would come out whatever shape the plastic faceplate was. Aluminum extrusion is made in a similar fashion but with the added element of high heat and high [hydraulic] pressure. Aluminum has many unique physical characteristics, which makes the extrusion process very practicable. Its malleability allows it to be easily machined or cast, while aluminum’s structural rigidity offers strength and stability. For these reasons, aluminum is used for a wide range of purposes!
