Aluminium is a versatile resource. We have often reported on the environmental aspects and advantages of secondary aluminium. The areas of application in architecture are also widely known. But aluminium has not exhausted its possibilities as a resource: the metal also contributes to an important development in quantum computers. Qubits as the smallest computing unit
The porous aluminium oxide layer that is present after anodising or colouring is still unsealed. This state would not provide long-term protection, e.g. on building surfaces. Subsequent sealing of these layers is therefore essential for long-term protection. In addition to the frequently used hot sealing, it is also possible to seal the aluminium oxide
Energy costs have been rising in many countries around the world in recent months. Electricity and gas prices in particular are affected by enormous price increases. But what can anodising companies do about this cost increase in the short term? There are some ways to make your own processes more energy efficient. Direct savings in
In classical, electrolytic colouring of aluminium surfaces with tin salts, uniform colourings from bronze to black are obtained with correct operation and the right colouring bath settings. However, sometimes you can observe inhomogeneous colouring on the goods carrier, so that a glance at the goods is enough to recognise the non-uniformity. Typical electrolytic colouring process
Even small mistakes while cleaning aluminium surfaces can lead to unsaleable goods in the anodising plant. It is therefore always worthwhile to take a look at the raw material that is about to be pretreated. If there are still residues of adhesive tapes or protective films on the surface, these will most likely be visible
On anodised, electrolytically black-coloured and hot-sealed aluminum we see deposits – what could that be? After hot sealing, deposits are often visible on anodised and coloured surfaces, which are then quickly classified as so-called ” sealing smut”. However, if closer inspection reveals that all sealing conditions were in order, the search for the possible defect
