Introducing Aluminium

Aluminum alloys are utilized much more frequently in commercial applications than 100 % pure or pure aluminum , because within an unalloyed state the materials properties are unsuitable for machining: The machining behavior of pure aluminum is challenging and lubricious. Furthermore, the materials at 660 ° C has a very low melting point, not to mention the high thermal conductivity of the steel and its own also high thermal growth coefficient. This makes it challenging to weld .

The aluminium is therefore blended with certain foreign metals, which positively change the physical properties of the light metal depending on the application form. The aluminium is as a result alloyed – it created in this way different aluminum alloys .

The classification of aluminum alloys

An alloy is normally by description a metallic materials comprising at least two components . Regular alloy constituents of an lightweight aluminum alloy admixed with the base material Al99.5 are, for example, beryllium, magnesium, manganese, copper, nickel, silicon, zinc and tin.

Primarily designed by the alloy strength ideals of the materials are improved, but also additional properties can be influenced based on the alloy element, to ensure that it, for instance, l judges welded could be made. When it comes to increasing the strength, this is often done by work hardening after the alloying elements have already been added.

The curing can also be achieved by heat treatment. Depending on www.aluminiumsupplier.com.cn , the material can be divided into normally hard or curable aluminum alloys , and in addition in aluminium wrought alloys and light weight aluminum casting alloys. The former are prepared by extrusion or rolling, while light weight aluminum casting alloys are produced by casting, as the name suggests.

From this it can be deduced what can arise from the particular aluminum alloys. While light weight aluminum profiles, light weight aluminum tubes or light weight aluminum sheets can be produced from wrought alloys using the rolling or extrusion procedure, casting alloys are used to manufacture parts, for example motor housings or so on.
