John Ferreol Monnot, metallurgist, the inventor of the first successful process for manufacturing copper-clad steel. Copper-clad steel (CCS), also known as copper-covered steel or the trademarked name Copperweld is a bi-metallic product, mainly used in the wire industry that combines the high mechanical strength of steel with the conductivity and corrosion resistance of copper.
The major use for high-yield copper is in flashing products, where malleability and strength are both important. The thickness of sheet and strip copper is measured in the U.S. by its weight in ounces per square foot. Thicknesses commonly used in construction in the U.S. are between 12 ounces (340 g) and 48 ounces (1,400 g).
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'.
The original use, however, was for watch springs: the copper cladding prevented corrosion. The company was founded as the Copper-Clad Steel Company, but in 1924, changed its name to the Copperweld Steel Company. In 1927, the company installed itself in a former axe factory in Glassport, Pennsylvania.
In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. [1] Cladding can be made of any of a wide range of materials including wood, metal, brick, vinyl , and composite materials that can include aluminium, wood, blends of cement and recycled polystyrene ...
Copper belfry of St. Laurentius church, Bad Neuenahr-Ahrweiler Metals used for architectural purposes include lead, for water pipes, roofing, and windows; tin, formed into tinplate; zinc, copper and aluminium, in a range of applications including roofing and decoration; and iron, which has structural and other uses in the form of cast iron or wrought iron, or made into steel.
Revere Ware has since been reintroduced, as World Kitchen currently (as of 2016) offers select variations: Copper-cored stainless steel, traditional copper-clad bottomed cookware and anodized non-stick aluminum. As of 2018, World Kitchen has ceased operations and the Revere Ware line is no longer in production. [5]
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% silver and 79.1% copper, and its clad layer was 80% silver and 20% copper. Half dollars struck since 1971 are produced identically to the dimes and quarters.
