6061 Aluminium Extrusion is a precipitation-hardened aluminium alloy that primarily contains magnesium and silicon as its main alloying elements. Originally known as “Alloy 61S,” it is recognized for its strong mechanical properties, making it suitable for a wide range of structural and engineering applications.

This alloy also offers excellent weldability and is commonly used in extrusion processes due to its versatility and durability. As one of the most widely used aluminium alloys for general-purpose applications, 6061 aluminium extrusion is valued for its balance of strength, workability, and corrosion resistance.
