TECU® Oxid

Right from the start, TECU® Oxid has a dark oxidised surface, to bypass the bright initial appearance of new copper and thereby offer a more consistent dark brown colour across different façade elements sooner than TECU® Classic. It resembles the oxidised matt brown surface that gradually develops on copper via natural weathering and oxidation. The copper coils are pre-oxidised at the factory on both sides in a special industrial process.

The brown oxide surface continues to develop after installation; it becomes matt and transforms through dark brown colours, yielding the rich dark brown hues of oxidised copper to the facade. On inclined cladding areas, a patina green, typical for copper, develops through the influences of airborne substances and moisture.

This lively protective layer lends TECU® Oxid its unmistakable appeal and extraordinary durability.

TECU® Oxid coil is manufactured in state-of-the-art production facilities to EN 1172 and KME's own strict guidelines. It is made from Cu-DHP – oxygen-free, phosphorus-deoxidised copper with limited residual phosphorus. Cu-DHP is well suited to welding and soldering, and is minimum 99.9% pure copper. Cu-DHP is outstandingly malleable, regardless of temperature or rolling direction. TECU® Oxid surpasses the requirements of EN 1172 regarding tolerances and the most important material properties. This gives cladding areas their excellent visual appearance.

The special manufacturing technology used for TECU® Oxid creates lighter and darker shades of brown, but these colour variations later disappear as the natural oxidation process progresses.

TECU® Oxid is especially suitable for all metal-working processes & techniques, from traditional seaming to modern cladding fabrication. TECU® Oxid can be processed like bright rolled copper using standard techniques and machines. However, due to the Oxid surface's special nature, a few important guidelines on processing, material properties, transportation and storage should be kept in mind.
