The Importance Of Aluminium

aluminium extrusion supplierAluminum alloys are used a lot more frequently in industrial applications than real or pure lightweight aluminum , because in an unalloyed condition the material properties are unsuitable for machining: The machining behavior of 100 % pure aluminum is tough 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 difficult to weld .

It might be that a few of these characteristics are needed in specific areas, however the properties and requirements that are in keeping demand can’t be met or met with pure aluminum. The lightweight aluminum is therefore mixed with certain international metals, which positively alter the physical properties of the light metallic depending on the application form. The light weight aluminum is consequently alloyed – it produced in this way different light weight aluminum alloys .

The classification of light weight aluminum alloys

An alloy is by description a metallic materials comprising at least two components . Standard alloy constituents of an aluminum alloy admixed with the bottom 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 other properties could be influenced based on the alloy element, so that it, for example, l judges welded could be made. When it comes to increasing the strength, this could be done by work hardening following the alloying elements have already been added.

The curing can also be achieved by heat treatment. Based on , the material could be divided into naturally hard or curable aluminium alloys , and in addition in lightweight aluminum wrought alloys and lightweight aluminum casting alloys. The previous are prepared by extrusion or rolling, while aluminium casting alloys are made by casting, as the name suggests.

From this it could be deduced what can occur from the particular aluminum alloys. While light weight aluminum profiles, aluminium tubes or aluminium sheets can be created from wrought alloys using the rolling or extrusion process, casting alloys are accustomed to manufacture parts, for example engine housings or so on.
