2. Copper foil - Wikipedia

   en.wikipedia.org/wiki/Copper_foil

   Copper foil is a thin sheet of copper metal that is widely used in various applications due to its excellent electrical conductivity, malleability, and corrosion resistance. It is an essential material in the electronics industry, especially for manufacturing printed circuit boards (PCBs) and other electronic components.

   The quality of the edge can be mirror smooth and a precision of around 0.1 mm (0.0039 in) can be obtained. Cutting speeds on thin 1.2 mm (0.047 in) sheet can be as high as 25 m (82 ft) per minute.

4. Copper cladding - Wikipedia

   en.wikipedia.org/wiki/Copper_cladding

   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'.

5. Cladding (metalworking) - Wikipedia

   For example, dimes and quarters struck since 1965 have cores made from pure copper, with a clad layer consisting of 75% copper and 25% nickel added during production. Half dollars struck from 1965 to 1969 for circulation and in 1970 for collectors also incorporated cladding, albeit in the case of those coins, the core was a mixture of 20.9% ...

6. Rolling (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Rolling_(metalworking)

   For thin sheet metal with a thickness less than 200 μm (0.0079 in), [citation needed] the rolling is done in a cluster mill because the small thickness requires a small diameter rolls. [10] To reduce the need for small rolls pack rolling is used, which rolls multiple sheets together to increase the effective starting thickness.

7. List of copper alloys - Wikipedia

   Example of a copper alloy object: a Neo-Sumerian foundation figure of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA) Copper alloys are metal alloys that have copper as their principal component.
