Aluminium is everywhere, from the bauxite mines to the sleek products we use daily. But how well do we understand the journey of this versatile metal? That’s where AL Pedia, a knowledge hub under AL Learn, comes in.
Through AL Pedia, we’re building an easy-to-follow A-Z encyclopedia of aluminium, covering key terms from across the aluminium value chain. Whether a student, a professional, or simply curious about the industry, this is your go-to space for breaking down complex concepts into simple and digestible insights.
Each week, we update 10 key terminologies, starting with the basics like Bauxite, Alumina, and Aluminium, and gradually moving through the refining, production, and downstream processes. You can find these posts on our Instagram and LinkedIn pages, making learning accessible anytime, anywhere.
A
- Aluminium: Aluminium is a lightweight, durable and infinitely recyclable metal that plays a vital role in modern industrial and sustainable development.
- Alloy: An alloy is a metallic substance formed by combining aluminium with other elements to enhance strength, durability, and performance for specific applications.
- Alumina: Alumina, or aluminium oxide, is a white crystalline substance refined from bauxite and serves as the primary raw material for aluminium production.
- Anodising: Anodising is an electrochemical process that forms a protective oxide layer on aluminium, improving its corrosion resistance, surface hardness, and aesthetic appeal.
B
- Bauxite: Bauxite is the primary ore of aluminium, rich in aluminium hydroxide minerals and essential for aluminium production.
- Bayer Process: The Bayer Process is the principal industrial method for refining bauxite into alumina through caustic digestion, clarification, precipitation and calcination.
- Billet: A billet is a solid, semi-finished aluminium product with a cylindrical shape, used as feedstock for extrusion, forging, or rolling processes.
