TECU® Brass | Facade

„Copper Alloys for Façade Cladding“

TECU ® quality copper alloys are exciting new highlights in façade design. Lively, distinctive and durable – typical of TECU ® products. High-quality, easy to work with and with the same striking aesthetic qualities as in the whole line of TECU ® surfaces – but with their own individual character.
TECU ® Brass, TECU ® Bronze and TECU ® Gold offer architects completely new creative possibilities for façade solutions – with unmistakable, high-quality surfaces that are just as astounding and inspiring as copper itself.

TECU® Brass
Time tested as an alloy, redefined for architecture: Brass, one of the best known copper materials, is now available in the new TECU® Brass grade, created by blending a spezial alloy of copper and zinc. The result is an extremely robust façade material that changes dramatically when exposed to the atmosphere, as uniquely as pure copper.

Weathering changes the original reddish golden colour of TECU® Brass; after the initial matting the surface takes on a greenish brown tone, which slowly turns greyish brown before evolving into a dark brown-anthracite colour. On sloping surfaces, patina layer – typical of copper, yet totally unique – gradually develops.

The individual aesthetic features have further impressive advantages: TECU® Brass offers outstanding mechanical abrasion resistance, extremely high corrosion resistance and durability as well as exceptional stability and material rigidity. The material can be cold-formed exceptionally well and is easy to solder. Because of its special material properties TECU® Brass is also ideally suited for large-scale applications.

The surface of TECU® Brass is covered with a protective film for safe transporting and working on the construction site. The protective film should be removed immediately after installation.

TECU® Bronze
Bronze – an alloy of copper and tin and also a synonym for metallic works of art. While artists have long benefited from its properties, architects are now also able to make optimum use of the material – for more individuality in façade design.

The original warm reddish-brown colour of TECU® Bronze develops distinctively through weathering. 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.

TECU® Bronze also offers a number of economic and technical advantages, including outstanding mechanical abrasion resistance, extremely high corrosion resistance and durability, as well as exceptional stability and material rigidity. The material can be coldformed exceptionally well and is simple to join by soldering or brazing.

TECU® Gold
A copper combination – as good as gold

Gold doesn’t always have to glitter: TECU® Gold, a new copper-aluminium alloy for façade cladding, oxidises very soon after it has been installed on the building – gradually forming a striking warm golden surface which, although it doesn’t glitter, is still unmistakably reminiscent of a valuable precious metal.

Façades clad with TECU® Gold have a distinctive, pleasing and unique quality. So this impression lasts, the surface changes very little over time. Further colour changes due to patination processes are hardly noticeable on the façade surfaces.

TECU® Gold is a CuAl5-grade alloy of copper and aluminium. When subjected to the influences of the weather the original greenish golden tone develops its own unique character. Like all TECU® quality alloys, TECU® Gold also offers outstanding mechanical abrasion resistance, extremely high corrosion resistance and durability as well as exceptional stability and material rigidity. The material can be easily cold-formed and processed with the manual techniques that are normally used for copper. Because of ist special material properties TECU® Gold is also ideally suited for large-scale applications.
