The use of aluminium metal is the common denominator for all Sapa’s businesses. Around 8% of the Earth’s crust consists of aluminium in the form of different minerals. So aluminium is one of the few metals for which the availability of raw materials is literally unlimited.
Aluminium - the properties
Material properties such as light weight combined with high strength and resistance to corrosion contribute to low environmental loading. After iron, aluminium is now the second most widely used metal in the world.
This is because aluminium has a unique combination of attractive properties:
• Low weight
• High strength
• Superior malleability
• Easy machining
• Excellent corrosion resistance
• Easy to mill, drill, cut, punch, bend, weld, bond, tape...
Aluminium can be reused for the same purposes over and over again. Unlike many other materials, aluminium does not lose its unique properties.
