In the manufacturing of rolled aluminium for brazed heat exchangers within Gränges there are several different process steps involved – from melting and casting to the final slitting and packaging. Each process step has its complexity as for instance the cladding process where one or several clad alloys are bonded to the core via the hot rolling process.
