Aluminium properties and advantages

The aluminum production is carried out according to the Bayer process. It is produced from bauxite, which is its main source. The purity of the aluminum thus obtained is higher than 99% and with a further refinement it can reach purity up to 99.99%. The higher the purity value, the greater its resistance to chemical influences and the better its electrical conductivity aluminium extrusion singapore.

However, the pure aluminum thus obtained is softer than its alloys in combination with, for example, copper, manganese, silicon, magnesium and zinc. Alloys have better properties and more mechanical strength, low density and high strength. Some alloys achieve high resistance to corrosion and chemical influences, hardness and toughness and are easy to mold and cast. Corrosion resistance can be further increased by thickening the surface oxide layer by anodizing.

Due to these properties, and in particular the low density and lightness of the material itself.

Aluminum is a very versatile material, and is therefore the second most used metal after steel, but it is possible that it surpasses it also thanks to its excellent strength / weight ratio. The demand for aluminum is huge. The annual world consumption of aluminum is 48 million tons and 20 million tons of aluminum in its revised forms.

Reflectivity

Aluminum has a high level of reflectivity in the electromagnetic spectrum which includes light and heat. These characteristics are extremely important for aluminum shutters, as aluminum reflects about 80% of the light and 90% of the heat that hits their surface. In addition to the perfect properties of aluminum suitable for shutters and blinds, the reflectivity of aluminum also increases their visual and aesthetic value.
