There are four main techniques used today in the UK and mainland Europe for copper cladding [1] [2] a building: seamed-cladding (typically 0.7 mm thick copper sheet on the facade): max 600 mm by 4000 mm 'seam centres'. shingle-cladding (typically made from 0.7 mm thick copper sheet): max 600 mm by 4000 mm 'seam centres'.
Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color.

Copper, silver and brass can be either cooled slowly in air, or quickly by quenching in water. [1] In this fashion, the metal is softened and prepared for further work such as shaping, stamping, or forming. Many other materials, including glass and plastic films, use annealing to improve the finished properties. [2] [3]
A typical European casting alloy contains 94% tin, 1% copper and 5% antimony. A European pewter sheet would contain 92% tin, 2% copper, and 6% antimony. Asian pewter, produced mostly in Malaysia, Singapore, and Thailand, contains a higher percentage of tin, usually 97.5% tin, 1% copper, and 1.5% antimony. This makes the alloy slightly softer.
Copper was the first metal in common use for tools and containers since it is one of the few metals available in non-oxidized form, not requiring the smelting of an ore. Copper is easily softened by heating and then cooling (it does not harden by quenching, e.g., quenching in cool water).
