Abstract
A self-brazing material 10 for use in a heat exchanger 50 using a corrosive heat exchanger fluid is manufactured by providing a first substrate layer 10 and a second layer 12 metallurgically bonding the two layers together to form a composite material 22. This second layer 12 is made of a material chosen from a group consisting of materials capable of having good high temperature and corrosive properties, and melting at a temperature well below that of the first material 10. The bonded material 22 is then reacted so as to render the second layer 12 a brazing layer for the first substitute layer 10 with excellent high temperature and corrosive properties.
