Aluminium Latest News

New research has found aluminium can be made to behave in the same way that makes transition metals such as palladium, rhodium, and platinum.

About Aluminium

• It is a chemical element with symbol Al and atomic number 13. 
• It is classified as a post-transition metal, 
• Aluminium Ore derived from bauxite, is one of the most abundant, versatile, and strategically important metals in the world.
• The transformation of bauxite into aluminium is a two-stage industrial process:
  • Bayer Process: The raw bauxite is first crushed and treated with sodium hydroxide to separate aluminum hydroxide. This is then calcined (heated strongly) to produce alumina (Al₂O₃).
  • Hall- Héroult Process: The alumina is smelted using electrolytic reduction, requiring enormous amounts of electricity, which makes aluminium one of the most energy-intensive metals to produce.

Properties of Aluminium

• It is a hard, strong, silvery-white metal with low density.
• It has high thermal conductivity, excellent corrosion resistance.
• It has high malleability and ductile properties.
• Lightweight & corrosion-resistant: Ideal for transportation and construction.
• Recyclable: Retains its original properties and requires only 5% of the energy compared to primary production.

Applications of Aluminium

• Transport: Aircraft, automobiles, ships, and rail coaches.
• Household & Packaging: Utensils, appliances, and aluminium foils.
• Infrastructure: Doors, windows, screens, and cladding.
• Electrical: Good conductor, used in transmission lines.
• Strategic Applications: Defence, nuclear industries, and aerospace.
