Abstract
A method for forming a tube coupling includes forming a metallurgical joint between a copper tube and an aluminum tube and annealing the copper tube and the aluminum tube after forming the metallurgical joint. The metallurgical joint has a eutectic region and an intermetallic region after annealing the copper tube and the aluminum tube. The method may assist with improving a performance of the metallurgical joint. A related tube coupling and evaporator are also provided.
