Alufinish has reason to celebrate. After 10 years of intensive outdoor weathering tests, the chrome-free corrosion protection process Alfipas 7816 has met the highest quality requirements of the GSB International e. V. quality association. This is a remarkable success for Alufinish and proof of the product’s quality. It is also the third Alufinish pretreatment process
Gold colouring baths based on ferrioxalates have been used successfully for decades to colour anodised components for interior and exterior applications. During the colouring process, the iron salts are then incorporated into the porous anodised layer by a simple dipping process. Depending on the amount of salts incorporated, the coloured surface then appears in intensive
Occasionally, it arouses astonishment when, after anodising the products, profiles unexpectedly appear that show a differently pronounced iridescent colouring of greenish, reddish and violet tones. This phenomenon does not originate from a pioneering colouring technique, but is rather the result of challenges during anodising. What is the cause? The correct contact is undoubtedly an essential
Aluminium is one of the most widely used metals on our planet. It is light, corrosion-resistant and has many applications, from the packaging industry to aerospace. However, extracting aluminium from raw materials requires a lot of energy and leads to significant environmental impacts. Therefore, aluminium recycling is becoming more and more important, and this is
The aluminium sector is crucial in achieving Europe’s goals of a climate-neutral and circular economy. Aluminium is recyclable and suitable for multiple recycling. Why recycle aluminium? Aluminium can be recycled again and again without losing its original properties. The aluminium recycling process also requires only 5 % of the energy needed to produce primary aluminium,
It is well known in anodising operations that, over time, deposits accumulate on the plastic balls used to cover (minimise heat and evaporation loss) hot sealing baths. Unwanted white residue: a common problem that can be addressed These usually show up as white, crust-like residues that are deposited and strengthened on the cover balls by
