Anodizing Colour & Structure techniques

Alumet also contributes
to a better climate
for the future

The need to reduce CO2, reuse materials, mitigate global warming is now widely known.

 

Alumet also wants to contribute to this. By reusing materials as much as possible, and applying the latest techniques. Our new state-of-the-art anodizing line uses the latest techniques to use much less energy and water.

Our Anodize methods
give a colourfast (UV resistant) result

Dying with inorganic dyes

Coloring with inorganic dyes is possible, for example, with a single-phase stain, such as when using ferric ammonium oxalate. This gives a gold-like color, but in low concentration the color 'new silver' is created. This technique and color is available at Alumet under the name AluGold.

Electrolytic colouring

For electrolytic coloring, Alumet uses metals from metal compounds, such as tin from a solution of tin sulphate. This gives colors from light copper to black. When using copper sulphate, colors appear between light pink and cardinal red. The advantage of this electrolytic coloring is that it produces very lightfast colours. These colors are available at Alumet under the names AluBronze en AluRed. By coloring aluminum 2x electrolytically, the colors are available under the name AluOldCopper

Combination colouring: electrolytic and inorganic

The use of new, very lightfast, inorganic dyes in combination with electrolytic colouring is becoming increasingly common, for example in the colours ‘copper’ and ‘brass’. In this process, we first perform electrolytic colouring, followed by ferric ammonium oxalate dyeing. Alumet produces these colours under the names AluCopper en AluBrass

Interference colouring

Interference colouring is a relatively new colouring process, which can also be considered a colour mixing system. This process not only works with colour, but also with refraction (interference). Following the anodisation process in direct current sulphuric acid by a treatment in acid and alternating current makes it possible to enlarge the lower part of the pore. This is followed by electrolytic metal deposition. This results in the colours grey, blue and green. Alumet also performs this interference technique under the names AluGrey, AluBlue en AluGreen.

Panelox

Technology with
many possibilities

Panelox is a special anodizing technique and exists, unlike most common techniques , made of two anodized layers: matte and gloss shades and an etched design. This is a unique element of Panelox and therefore offers many possibilities. You can combine one or two colours with a design. Panelox gives a panel an impressive appearance!
