KME TECU Copper Bronze Datasheet

Bronze an alloy of copper and tin and a synonym for metallic works of art. While artists have long made use of bronze, architects are now also able to make optimum use of the material for more refinement in façade design. The original warm reddish-brown surface of TECU® Bronze develops in a distinctive manner through weathering. A brown-red surface oxidation with a brown-grey undertone is typical for this alloy; the material then gradually changes to dark brown anthracite throughout. The subsequent patina coating forms much more slowly than with pure copper.
