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.
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 ).
In the case of CCA, or copper-clad aluminum, the key benefit over solid copper is lighter weight and flexibility. In late 2013, Copperweld Bimetallics LLC, the company's American subsidiary, purchased most of the assets of its biggest American competitor, the Bimetals division of CommScope , relocating their equipment from Statesville, North ...
Due to poor corrosion resistance, it is often clad with aluminium or Al-1Zn for protection, although this may reduce the fatigue strength. [1] [2] In older systems of terminology, 2XXX series alloys were known as duralumin, and this alloy was named 24ST. 2024 is commonly extruded, and also available in alclad sheet and plate forms.

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% ...
