Choosing Aluminium

aluminium extrusion supplierAluminum alloys are utilized much more frequently in commercial applications than genuine or pure lightweight aluminum , because in an unalloyed state the materials properties are unsuitable for machining: The machining behavior of real aluminum is difficult and lubricious. Furthermore, the materials at 660 ° C has a very low melting point, not forgetting the high thermal conductivity of the metal and its own also high thermal growth coefficient. This makes it tough to weld .

It could be that a few of these characteristics are required in specific areas, however the properties and requirements that are in common demand can’t be met or fulfilled with 100 % pure aluminum. The light weight aluminum is therefore blended with certain international metals, which positively modify the physical properties of the light metallic depending on the application form. The light weight aluminum is as a result alloyed – it created in this way different aluminium alloys .

The classification of light weight aluminum alloys

An alloy is usually by definition a metallic materials comprising at least two elements . Usual alloy constituents of an lightweight aluminum alloy admixed with the base material Al99.5 are, for instance, beryllium, magnesium, manganese, copper, nickel, silicon, zinc and tin.

Primarily meant by the alloy strength ideals of the material are improved, but also additional properties could be influenced based on the alloy component, so that it, for instance, l judges welded can be made. When it comes to increasing the power, this is often done by work hardening following the alloying elements have been added.

The curing can also be achieved by heat treatment. Depending on Aluminium Extrusion Supplier , the material can be divided into naturally hard or curable aluminium alloys , and in addition in aluminum wrought alloys and aluminum casting alloys. The former are processed by extrusion or rolling, while aluminum casting alloys are produced by casting, as the name suggests.

From this it could be deduced what can arise from the respective aluminium alloys. While lightweight aluminum profiles, light weight aluminum tubes or aluminum sheets can be created from wrought alloys using the rolling or extrusion process, casting alloys are accustomed to manufacture parts, for instance electric motor housings or so on.
