Abstract
This application discloses a material including an aluminum metal alloy cladding fusion-cast to a metal alloy core. Also disclosed is a material having a metal core with a high content of scrap metal and having two sides, a first aluminum metal cladding fusion cast to the first side of the core layer, and a second aluminum metal cladding fusion cast to the second side of the core layer. The materials can be in a form of a sheet. Sheets are roll bonded together to create permanent metallurgical bonds except at regions where a weld-stop ink is applied. The sheets are used to make corrosion resistant heat exchangers.
