Laboratory trial to precipitate a consumed gold colouring bath

Benedikt Wolter — Mon, 18 Sep 2023 07:45:29 +0000

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 […]

Versatile aluminium: Quantum computers with aluminium technology

Benedikt Wolter — Wed, 25 Jan 2023 18:38:21 +0000

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 […]

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 […]

More “grip” when powder coating by using Acidic Alfideox etching systems

Benedikt Wolter — Sun, 13 Feb 2022 14:07:15 +0000

In addition to a good cleaning of the surface, a good etching of the material is particularly important when powder coating aluminium. In addition to removing oxide residues and other surface residues that are not removed during cleaning, acid etching with Alfideox enables the surface to be roughened. This in turn gives the subsequent […]

Alfideox helps with desmutting problems

Benedikt Wolter — Wed, 19 Jan 2022 17:52:43 +0000

The desmutting of etched or chemically polished aluminium surfaces is important to remove remaining tarnish and oxide layers before the anodisation process. This avoids possible staining or color changes of the anodised product. Often, the normal desmutting resources such as nitric acid, sulfuric acid or spent anodising bath solution are not sufficient to remove all […]

Lithium-ion battery was yesterday: aluminium as battery material

Benedikt Wolter — Fri, 03 Sep 2021 11:52:03 +0000

Everyone knows them, at least since electric mobility became the topic of our century: The lithium-ion battery. Thanks to its high capacity, chargeability and service life, it is generally regarded as the battery for electrical technology. But there is one element that seems even more suitable: aluminium. Yes, that’s right. Aluminium is proving to be […]

Powder-coated aluminium facades

Benedikt Wolter — Mon, 24 May 2021 07:37:00 +0000

A significant advantage of powder-coated aluminium surfaces is that, compared to anodised components in the architectural sector, a great many colour variations are possible. This is certainly one of the reasons why initial efforts were made in this area as early as the end of the 1960s. Just think of the pure white facade surfaces, […]

Chemical pre-treatment for window construction -Part 1: Anodised window profiles

Benedikt Wolter — Wed, 12 May 2021 14:48:55 +0000

A small aluminium pyramid about 22 cm high was mounted on the Washington Monument in the USA as early as 1884 as an aesthetic lightning rod. It is hard to believe that at that time aluminium, which was still rare, was more expensive than silver. This aluminium spike is also considered the first known use […]
