Where to Head When You Need the Best Aluminium Extrusions
Understanding aluminium extrusion process
Aluminium extrusion is a process by which a billet made of an aluminium alloy is forced to pass through a die with a particular cross-sectional profile. The extruded shapes differ according to the die shape of the cross-sectional profile. They could be of three main kinds;
a) Solid, with no enclosed voids or openings like in a rod, beam, or angle,
b) Hollow, with one or more voids like in square or rectangular tube or
c) Semi-hollow, with a partially enclosed void like in a “C” channel with a narrow gap
During the process a powerful press rams or pushes the alloy through the die and the extruded aluminium emerges on the other side in the desired shape. Hydraulic presses can exert anything between 100 tons to 15,000 tons of pressure and the size of the extrusion produced is determined by the pressure capacity of the press.
At the onset of extrusion, the billet is still in solid state, but has been softened in a furnace to aid casting. When pressure is applied, the billet is pressed hard against the die and becomes shorter and wider as much as the container walls permits. When the pressure keeps increasing, the billet has no choice but squeeze out through the die with the specific shape and emerge on the other side as a fully formed solid profile.
The profile is then cut off at the die and the still-hot extrusion is quenched, mechanically treated or aged, to give it the desired physical and metallurgical properties. After required ageing is completed, profiles can be cut, bent, welded and are ready to be shipped.
Aluminium extruded in this manner has many applications across various industries like architecture, construction, automobile, electrical, electronics, energy and aerospace to name a few. Aluminium extrusion process eventually results in 8 to 24 feet long profiles that can then be heat treated, finished, and fabricated according to customer specifications.
