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]
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 ).
Another issue is the joining of aluminum wire to copper wire. In addition to the oxidation that occurs on the surface of aluminum wires which can cause a poor connection, aluminum and copper are dissimilar metals. As a result, galvanic corrosion can occur in the presence of an electrolyte, causing these connections to become unstable over time.
Latten is a further term, mostly used for coins with a very high copper content. Today the term copper alloy tends to be substituted for all of these, especially by museums. [1] Copper deposits are abundant in most parts of the world (globally 70 parts per million), and it has therefore always been a relatively cheap metal.

The largest human exposure to metals is ingestion; while food or drink containing metals can cause an allergic reaction in people who already have an allergy, it's not clear if it can cause a new allergy, as of 2021. Some metal allergens are nutritionally necessary to humans. Airborne metals have been linked to higher rates of sensitization.
