  • Heat exchanger assembly with magnesium barrier
    Patent number: 6234243
    Abstract: The invention involves a heat exchanger assembly comprising at least one aluminum based tube including magnesium, an aluminum based cladding, and at least one aluminum based component disposed adjacent the cladding. A brazing flux is applied to a joint between the cladding and the component to facilitate brazing in an ambient atmosphere. An aluminum based lithium enriched layer is disposed between the tube and the cladding to scavenge sufficient oxygen from the ambient atmosphere to form an effective barrier against the defusion of magnesium from the tube.
