In this article we will discuss about:- 1. Evaluation of Aluminium as Building Material 2. Economics of Using Aluminium 3. Forms 4. Uses 5. Conclusion. Evaluation of Aluminium as Building Material: The building industry occupies a very important place in the national economy in terms of capital input and employment potential. The industry is dominated by materials like brick, cement, [...]
In this article we will discuss about the classification of wrought aluminium alloys. 1. Non-Heat Treatable Aluminium Alloys: These aluminium alloys do not respond to age-hardening heat treatment. It may be that these alloys do not show decrease of solid solubility with the decrease of temperature in their constitution diagram, or do not form coherent precipitates. All these alloys have [...]

In this article we will discuss about:- 1. Production of Aluminium 2. Properties of Aluminium 3. Anodic Coating Treatment 4. Electro-Brightening or Electro-Polishing 5. Uses and Engineering Applications. Production of Aluminium: First stage in the production of aluminium is the production of alumina by chemical refinement of bauxite. Aluminium is then produced by the electrolysis of alumina dissolved in a [...]
Alloys of aluminium are light in weight compared to steel, brass, nickel and copper. These resist corrosion and have good electrical and thermal conductivities. These can readily accept a wide range of surface finishes and can be fabricated by all common processes. These lose part of their strength at elevated temperature. At sub zero temperatures, however, their strength increases without [...]
