How are U.S. cent coins manufactured ?

Hi.

Over twenty years ago, I was told that the cent coins (pennies) were made from zinc sheets with bonded copper foils above and under by a very high pressure explosive method, and then the blank rounds cut from the resulting layered sheet, to be later stamped at a mint.

 

Is that true ?

Thanks.

My poorly composed original post should had beed focused in the area of interest, the copper cladding of zinc as blank rounds metal source.

The process of minting is explained in several sites.

 

Do you know details about that process ?

 

Edited, added: Found something at many sites, by searching with proper terminology
