Aluminium shapes modern architecture: on façades, windows, doors, railings and solar shading. Many of these surfaces are natural in colour and show the typical metallic aluminium tone – others are bronze, black or coloured, matt or glossy. What they have in common is the surface treatment: it protects the metal and gives it its appearance
We encounter anodised aluminium surfaces every day: on façades, vehicle parts, furniture, lighting or technical components. They can be matt or glossy, natural or coloured. But what actually happens during anodising, and why does it require several carefully coordinated process steps? What does anodising mean? Anodising is the common term for the electrolytic oxidation of
From October 6 to 8, 2026, the international aluminum industry will gather at ALUMINIUM in Düsseldorf, and we’ll be right in the thick of it. You’ll find us in Hall 3 at Booth 3F45: featuring specific topics related to process costs, flexibility, and process reliability in surface treatment, with plenty of space for meaningful discussions,
The shift to electric vehicles is reshaping the demands placed on materials and supply chains. A new study by Transport & Environment (T&E) highlights aluminium as a key lever – and green aluminium as a viable route to significantly reducing emissions. Aluminium plays a critical role in EV design – from battery housings to chassis
In many production environments, energy costs have become one of the most important factors influencing the economic efficiency of industrial processes. Over recent months, energy prices have increased significantly in many regions, creating additional cost pressure for energy-intensive industries. In particular, anodising and coating operations are directly affected by this development, as energy consumption has
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 Faults After anodising, some components show iridescent rainbow colours
