Aluminium is a silvery-white metal with a melting point of 600 ° C. It has very low density and high electrical conductivity. There is no generally adopted nomenclature for the various degrees of purity of aluminium. The following classification is appropriate:
%
99.50 – 99.79 - commercially pure
99.80 – 99.949 - highly pure
99.950 – 99.9959 - super pure
99.9960 – 99.9990 - extremely pure
Over 99.9990 - ultra pure
Technical aluminium is produced in the form of sheets, profiles, rods and wire. Deformable aluminium alloys (duralumin) are mostly used in engineering.
The other group are aluminium alloys for die casting. These are alloy shaped casting with a lowl tendency for the formation of hot cracks, porosity with good mechanical properties and corrosion resistance. Mostly used are AL4, AL5, AL3, AL7, AL9, AL19, AL2, AL27.
We offer all kinds of products and aluminium profiles, powder and plates.
