KME Architectural Solutions - TECU® Bronze

TECU® Bronze is an alloy of copper and tin.‎ The original warm reddish-brown colour of TECU® Bronze has a distinctive appearance during natural weathering.‎ During initial weathering a reddish-brown colour develops across the surface in more ‘refined’ manner, to give a more even brown tone to a façade compared with TECU® Brass.‎ Over time, the surface darkens further to a rich dark brown on the façade.‎ On inclined cladding areas, eventual patina formation is significantly slower than that of classic copper, and has a unique appearance.‎Typical for this alloy is a brown-red oxidation of the surface with browngrey undertones; the material then very gradually changes to dark brown anthracite throughout.‎ The subsequent patina coating forms much more slowly than with traditional copper – and with very singular results.‎
