A copper strip is formed into the shape of a cylinder, while it is being wrapped around an aluminum core and the edges of the copper strip are welded together. The assembly is then pulled through a die, where the cladded wire is squeezed and stretched while also improving the bonding between the copper and the aluminum core. [1]
Copperweld is an American company based in Fayetteville, Tennessee, and maintaining a management office in Brentwood, Tennessee.Its main products are wire and stranded electrical cable made from its Copperweld brand copper-clad steel ("CCS") or copper-clad aluminum ("CCA"). [1]
In communist former East Germany (GDR, 1945-1990), aluminum or Copper-clad aluminium wire (″AlCu-Kabel″) had to be used for wiring as copper was expensive to import. [4] While all devices were designed for aluminum during that era, this ended with unification in 1990 when standard Western European equipment became available and the national ...
Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium , iron , nickel and silicon ( AlCu(Mg, Fe, Ni, Si) ), often manganese is also included to increase strength (see aluminium-manganese alloys ).
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.
Alclad is a heat-treated aluminium, copper, manganese, magnesium alloy that has the corrosion resistance of pure metal at the surface and the strength of the strong alloy underneath. Of particular importance is the thorough character of the union between the alloy and the pure aluminium.
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% ...
