In recent years the use of aluminium extrusions has increased significantly due to its versatility in design and its cost effectiveness. Although mill finish aluminium is not as strong as steel, when it is combined with another metal such as zinc, copper or magnesium, it becomes considerably stronger. It also increases in strength when it is heated which makes it particularly suitable for the extrusion process. This involves heating the aluminium until it softens and then forcing it through a pre-formed die.
Ideal Designing Qualities
Extruded aluminium is the first choice across a wide range of industries. It weighs far less per volume when compared to other metals, making it an essential element in aviation where it is used mainly for the fuselage and wings of aeroplanes. Extruded aluminium is guaranteed to be rust proof, a property which allows it to be used in the design of contemporary architectural structures where it will often be exposed to wet weather without its properties being diminished over time.
When heated, extruded aluminium is extremely malleable allowing it to be cast into complex three dimensional designs which are ideal for car panels, particularly of sports cars. It is also used in the design of ships, yachts and household items such as saucepans and tubular framed furniture. In fact, there is an infinite number of projects it can create. As a strong yet lightweight metal, aluminium responds well to being cut, drilled and shaped and is easy to handle during the manufacturing process, saving time and money on any project.
Thermal And Electrical Conductivity
Designs that are created for projects that will need to withstand the extremes of temperature are usually fabricated from extruded aluminium due to its thermal conductivity properties. Products created from extruded aluminium include air conditioning units, heaters, cookers, freezers … READ MORE
