Aluminium Alloys Classes

High ductility and low mechanical strength is the properties of very pure aluminium. Aluminium alloys is made by adding elements and they are divided into non heat-treatable and heat-treatable.

Precipitation-hardening process can form heat-treatable aluminium alloys. Quenching is a process which rapidly cool the alloying elements in water after heating to a high temperature. Under super-saturation, the quench metal is hardened by precipitation and the alloying elements are expelled as precipitates. 2000, 6000 and 7000 series are examples of heat-treated aluminium alloys.

Non heat-treated aluminium alloys comprise of the 1000, 3000 and 5000 series. The hardening is done by the combined effects of the alloying elements and of the work-hardening of the metal resulting from shaping and forming.

Aluminium 6061 is the most used in the 6000 series because it has high corrosion resistance, moderate tensile strength, good formability, beautiful surface finish and good weldability. Meanwhile, Alloy 5083 comprises of magnesium and aluminium and posses wide strength range, perform better forming and welding compatible. Its exceptional performance in extreme environments surely make it a high resistant alloy to corrosion including seawater and industrial chemicals. Containing aluminium, zinc and magnesium, Alloy 7075 is used in aviation, ultra-sonic components, and golf equipment. The 5052 Alloy is used in commercial flooring of public transportation and industrial applications. Essential to the aviation and aerospace, aluminium alloy MIC-6 is employ in fabrications.
