Anodising is one of the most established methods for finishing aluminium surfaces. However, even minor deviations in the process can lead to visible defects and non-saleable surfaces. This article outlines three common error patterns – and how to prevent them reliably.Iridescent Discolouration Due to Contact FaultsAfter anodising, some components show ...
The European Chemicals Agency (ECHA) has proposed a wide-ranging restriction on the use of hexavalent chromium (Cr(VI)) compounds. Known as potent workplace carcinogens, these substances are already subject to REACH authorisation – but could now face a general ban across the EU1. For businesses involved in metal pre-treatment – particularly ...
Alufinish is pleased to announce the approval of two innovative pre-treatment systems for aluminium surface treatment in the anodising sector. The certificates for Alfinox 510 (ENSAVAL process) and Alfiseal 1960 were officially awarded by the Qualanod Quality Association on 17 June 2025. This means that both products can now also ...
Aluminium is a versatile material – but transparent? The possibility of converting aluminium into a transparent form is not new — but until now, this was only possible at great technical and financial expense. Researchers at the Ateneo de Manila University (Philippines) have now developed a simplified process that produces ...
Aluminium has established itself as an indispensable material in digital technology. With its unique properties — lightness, robustness and excellent thermal conductivity — it is impossible to imagine modern electronic devices without it. Smartphones, laptops, and data centres all benefit from the advantages of this lightweight metal.Customised extruded profiles are ...
Im Rahmen eines Versuchs wurde untersucht, welche Verunreinigungen die Tiefenstreuung beim elektrolytischen Zinnfärben von Aluminium stören. Ziel des Versuchs war es, den Einfluss einzelner Fremdionen auf die Homogenität der abgeschiedenen Zinnschicht sowie auf die damit verbundenen optischen Streueigenschaften zu ermitteln. Versuchsablauf Für den Versuch wurden zunächst EN AW 5005 Metallstreifen ...
The aluminium industry is undergoing a significant transformation driven by digitalisation and Industry 4.0 concepts. These changes not only enhance efficiency but also introduce new business models and improved processes. For small and medium-sized enterprises, modernising production technologies and internal workflows is essential to remain competitive. Automation and Real-Time Data: ...
Eloxierte Aluminiumoberflächen zeichnen sich durch ihre schützende, keramikähnliche Oxidschicht aus, die jedoch in bestimmten Situationen feine Risse, sogenannte Mikrorisse, aufweisen kann. Diese Mikrorisse werden häufig erst bei schrägem Lichteinfall sichtbar, während sie bei direkter Betrachtung kaum auffallen. Sie sind ein Indikator für mechanische oder thermische Beanspruchungen der Oberfläche und stellen ...
Stellen Sie sich vor, ein Unternehmen entscheidet sich, seine Geschäftspraktiken neu zu definieren, um nicht nur wirtschaftlichen Erfolg, sondern auch eine nachhaltige Zukunft zu sichern. Genau das haben wir bei Alufinish getan. Unsere Reise begann nicht einfach bei der Einhaltung gesetzlicher Vorschriften. Sie begann mit einem tiefen Verantwortungsgefühl: der Bestrebung, ...
To enable the energy transition, it must be possible to store renewable energy efficiently and on a large scale. Recently, scientists have increasingly investigated metals as carbon-free chemical energy storage systems. The A-STEAM project now focuses on aluminium as a potential alternative energy source. The research project, led by Professor ...
