What is Aluminium Extrusion and its usage in industrial filed?


Aluminium Extrusion Process

The process of shaping material, such as aluminium, by forcing it to flow through a shaped opening in a die is known as extrusion. Extruded material comes out as an elongated piece with the same profile as the die opening.

After the desired shape and color are picked, the dough is inserted into the holding chamber and pressure is applied to it, which forces aluminium into a shape. In an extrusion press, pressure is applied to the billet by the ram where the dummy block is attached to the end of the ram stem. This principle applies to extrusions from aluminium billets but is more detailed and involves the usage of sophisticated technologies.

It is the press size that determines how large of an extrusion can be produced. The most significant factor that must be kept in mind in the extrusion process is the temperature as it gives aluminium its desired characteristics such as hardness and finish.

To sum up, Aluminium extrusion is a technique used to transform aluminium alloy into objects with a definitive cross-sectional profile for an array of uses. The extrusion process makes most of the unique combinations of aluminium’s physical characteristics. It is its malleability that allows it to be easily machined and cast. In spite of this, aluminium is one third the density and stiffness of steel so the resulting products offer strength and stability, that is, when alloyed with other metals.

Use of Aluminium Extrusion in Diverse Industries

  • Apart from ready work ability and substantial strength of aluminium, there are many other traits that offer benefits in various industries.
  • High conductivity of heat and electricity is a major benefit for aluminium extrusion products. The efficient transfer of heat makes aluminium a favourite for use in condenser tubes, radiators and air conditioners in the automobile industry, and in nuclear reactors.
  • The use of aluminium extrusion products is also there in the heating and cooling devices of mainframe computers, electronics, audio and video systems as well as in thawing units for the pharmaceutical industry.
  • Due to its low weight and high strength, aluminium extrusions are ideal for manufacturing aircrafts, cars, boats, subways, railway coaches, and trucks – this comprises, panels, cylinder heads, engine blocks, transmission houses, and chassis. It is because of the light yet strong characteristic that makes aluminium an optimal choice for manufacturing spacecraft bodies and parts.
  • As aluminium is corrosion resistant, it is used in mining to transport and dispose of mined materials and waste using tubing created with aluminium extrusion. That is because it is rust resistant and thus, suitable for military armaments.

Another property of aluminium is that it can be repeatedly recycled while maintaining its structural integrity. To add on, it is abundantly available in nature. Aluminium extrusion these days have become the most viable solution in order to meet the specific manufacturing needs of design flexibility, cost savings, and product performance.
