High strength CAB brazed heat exchangers using high strength fin materials

摘要

A heat exchanger assembly that includes a tube having an internal surface and an external surface. An aluminum-based component is disposed adjacent to the tube, the aluminum-based component has an aluminum-based material that has a magnesium content that is above 0.3%, wherein the aluminum-based component is joined to the tube using a brazing flux applied during a controlled atmosphere brazing process.
