ALUMINIUM ALLOYS
The alloys in which alluminium is a major components is called as alluminium alloys.alluminium alloys contains manganese, copper tin and lead are other major components.these alloys are usually used in air craft industries where light metals are employed to make aircraft bodies.alluminium alloys devalope an white coating due to the formation of alluninium oxide layer. In a moisture containing atmosphere, corrosion will happen when these alloys are kept with some other metals with more positive corrosion potentials than aluminium, and an electrolyte that helps ion transfer. Referred to as dissimilar-metal corrosion, this process will occure as scaling away or as intergranular decay.alluminium ions are usually improperly heat …show more content…

Selecting the right alloy for a given application entails considerations of its tensile strength, density, ductility, formability, workability, weldability, and corrosion resistance, to name a few. Aluminium alloys are used extensively in aircraft due to their high strength-to-weight ratio. On the other hand, pure aluminium metal is much too soft for such uses, and it does not have the high tensile strength that is needed for airplanes and helicopters. Because of its high conductivity and relatively low price compared with copper in the 1960s, aluminium was introduced at that time for household electrical wiring in North America. But the new use brought some …show more content…

Therefore, for a given load, a component or unit made of an aluminium alloy will have a greater deformation in the elastic system than a steel part of similar physical properties.Even though there are aluminium alloys with somewhat-greater tensile strengths than the usually used type of steel, simply substituting a steel element with an aluminium alloy may lead to problems.
With new metal products, the design choices are usually governed by the choice of manufacturing technology. Extrusions are important in this case, owing to the easeness with which aluminium alloys, particularly the Al–Mg–Si alloy, can be extruded to form complicated
