![]() ![]() Making the right design choices will yield significant benefits in terms of extrudability, manufacturing cost and design. Hence, it is one of the most commonly extruded materials.įor the above reason, this article will be biased towards aluminium alloy extrusions. Aluminium alloy extrusion has many advantages, such as being lightweight, having a high strength-to-weight ratio, corrosion-resistant, heat conductive, fully recyclable, having very tight tolerances, easy to fabricate and being cost-effective. The common metals used for extrusion are steel, copper and aluminium. The parts obtained after extrusion is called extrudates.ĭirect extrusion is the most common extrusion process used in profile extrusion, mainly due to its simplicity in the manufacturing design and flexibility in profile manufacturing. The dimensions of the extruded workpiece depend on the extruded profile and the amount of material that the workpiece withholds. But generally, the billets are heated up before pushing through the die to reduce friction and the force required. This metal-forming process can be performed both hot and cold. ![]() Direct metal extrusion is one of 5 main types of metal extrusion processes in which a metal billet is forced through a fixed die to create a specified shape. ![]()
