A little more about aluminium and its uses
Our caps are made from high-quality aluminium and are available in several sizes to fit all tubes. Aluminium is one of the most widely used metals in the world, in industry and laboratories, but also in crafts and transport. A soft, silvery-white, non-magnetic and ductile metal, it has good electrical and thermal conductivity. Aluminium is found in bauxite ore and is purified by the Hall-Héroult process (by electrolysis).
