The Meaning Of Aluminium

aluminium extrusion supplierAluminum alloys are used much more frequently in commercial applications than pure or pure aluminum , because in an unalloyed state the material properties are unsuitable for machining: The machining behavior of real aluminum is challenging and lubricious. In addition, the material at 660 ° C includes a suprisingly low melting point, not to mention the very high thermal conductivity of the steel and its own also high thermal expansion coefficient. This helps it be hard to weld .

It might be that some of these characteristics are needed in specific areas, however the properties and requirements that are in common demand can not be met or fulfilled with genuine aluminum. The light weight aluminum is therefore blended with certain international metals, which positively alter the physical properties of the light metallic depending on the application form. The lightweight aluminum is therefore alloyed – it produced in this way different aluminium alloys .

The classification of aluminum alloys

An alloy is usually by description a metallic material consisting of at least two components . Typical alloy constituents of an aluminium 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 increased, but also additional properties can be influenced based on the alloy component, so that it, for example, l judges welded can be made. When it comes to increasing the power, this could be done by work hardening after the alloying elements have already been added.

The curing may also be achieved by heat treatment. Depending on , the material could be divided into normally hard or curable light weight aluminum alloys , and in addition in light weight aluminum wrought alloys and light weight aluminum casting alloys. The previous 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 occur from the respective aluminum alloys. While light weight aluminum profiles, aluminium tubes or aluminium sheets could be created from wrought alloys using the rolling or extrusion process, casting alloys are accustomed to manufacture parts, for example electric motor housings or the like.
