Aluminum is a lightweight, corrosion-resistant metal that's strong, versatile, and 100% recyclable.

Aluminum is a lightweight, corrosion-resistant metal used in everything from airplanes to cans. Its versatility makes it a must-have in engineering and manufacturing.


What is Aluminum?

Aluminum (Al) is a lightweight, silver-colored metal and the third most common element in the Earth's crust. However, it doesn't naturally occur in pure form. Instead, it is extracted from bauxite ore using the Bayer process and then refined through smelting.

One of Aluminum's key advantages is its ability to form a protective layer when exposed to air, preventing rust and corrosion. This and its light weight make it a better choice than heavier metals like steel for many applications.


Key Properties

  • Lightweight – One-third the weight of steel.
  • Corrosion Resistant – Forms a protective oxide layer.
  • Strong & Ductile – High strength-to-weight ratio and easy to shape.
  • Conductive – Excellent heat and electricity conductor.
  • Recyclable – 100% reusable without losing quality.
