Although aluminum is the most prevalent mineral in the earth's crust, it is rarely seen in its pure form in nature. Aluminum is made from bauxite, a material that is mined all over the world, and it was not until 1888 that an economically viable technology for commercial production of aluminum was discovered. What are the advantages of using aluminum in volume extrusion?
The Advantages of Aluminum Extrusion
In comparison to alternative materials and methods, aluminum in general, and aluminum extrusions in particular, have a number of advantages. Aluminum is also popular in CNC machining and metal fabrication.
Aluminum extrusions are lighter than iron, steel, copper, or brass, making them easier to handle, less expensive to ship, and an appealing material for applications where weight reduction is a goal, such as transportation and other applications with moving parts.
Aluminum can be recycled indefinitely without losing its qualities, and aluminum extrusions are frequently made with a high recycled content — without sacrificing aesthetics or functionality. Furthermore, the inherent qualities of extrusions, such as light weight, strength, and design flexibility, result in significant environmental benefits when used.
Strong: Aluminum extrusions may be produced as strong as required for most applications, and because of the nature of the extrusion process, the strength may be concentrated where it is most needed by incorporating different wall thicknesses and internal reinforcing into the profile design. Extrusions are especially well-suited to cold-weather applications because aluminum strengthens as the temperature drops.
Aluminum extrusions have a unique mix of high strength and low weight, making them perfect for applications such as aircraft, truck trailers, and bridges where load carrying is a crucial performance factor.
Extruded components in vehicle crash management systems are resilient because aluminum combines strength and flexibility, and it can bend under pressure or spring back from the shock of collision.
Corrosion resistance: Aluminum extrusions are highly resistant to corrosion. They don't rust, and the aluminum's surface is protected by a naturally occurring oxide film, which can be improved through anodizing or other finishing procedures.
Excellent thermal conductors: Aluminum conducts heat and cold better than other popular metals in terms of weight and total cost, making extrusion excellent for applications that require heat exchangers or heat dissipation. Designers can maximize heat dissipation in housings and other components because to extrusion's design flexibility.
Aluminum extrusions are ideally suited for applications involving explosive materials or taking place in extremely flammable conditions because aluminum is non-sparking.
Electrical conductors of exceptional quality: Extrusion is a cost-effective solution for electrical connectors and bus bar distribution components since aluminum is twice as conductive as copper pound for pound.
Extrusions are beneficial in high-voltage applications and in electronics where magnetic fields are present since aluminum does not accumulate a magnetic charge.
Noncombustible and nontoxic: Aluminum does not burn and does not emit poisonous gases even at extremely high temperatures.
Aluminum extrusion is useful for lighting applications or for applications where areas must be shielded from light, radio waves, or infrared radiation due to surface treatments that can provide high reflectivity on aluminum components.
Seamless: Without the need for mechanical connecting, complex geometries can be achieved in one-piece extruded aluminum parts. The resulting profile is usually more durable than a comparable assembly, and it is less prone to loosen or leak with time.
Aluminum extrusions are a preferred element in many product solutions because they are easily tailored. While there are a variety of standard extrusion profiles available, the ability to design a profile to meet specific functional, aesthetic, and manufacturability objectives makes them a preferred element in many product solutions.
Quick-to-market: Aluminum extrusion tooling is relatively inexpensive (see material comparisons) and has very short lead times, making prototype creation, testing, and product launch much easier.
Easy to construct and assemble: Effective design of aluminum extrusions can substantially simplify subsequent fabrication and assembly, and extrusion-based components and assemblies are routinely produced using a wide range of fabrication procedures.
