Abstract
A method of cladding a nonaluminum core with at least one aluminum cladding strip by preheating both the core rod and the strip with the former being preheated to about 1000.degree. F. to 1300.degree. F. and the latter being heated to about 600.degree. F. to 1000.degree. F. Cleaning the core rod and the strip and passing them through a controlled environment chamber containing a reducing or neutral gas. Lubricating the bonding roll grooves to provide a substantially continuous coating of lubricant thereon. Galling of the aluminum strip or strips to the bonding rolls is resisted as a result of this process.
