PRODUCTION OF ALUMINIUM SOLDERED PLATE

摘要

Aluminum brazing sheet is produced by providing a composite assembly comprising an ingot of aluminum alloy and a layer of an aluminum brazing alloy on at least one side of the ingot. Provided on both sides of the composite assembly is a second layer of aluminum alloy substantially free of eutectic or elemental silicon. The composite assembly and the second layer are hot bonded and formed into brazing sheet by steps including hot rolling in a reversing mill followed by hot rolling in a continuous mill.
