A metal matrix () for a heat exchanger (), comprising a stack of components (), in particular etched plates or corrugations (), separator sheets () and bars (), or a combination of the two types of stack, said components () being held relative to one another by layers of braze material (), thereby ensuring the mechanical integrity of the matrix, the matrix including fluid circulation passages () within it, each fluid circulation passage () having an inner wall provided to fully contain said fluid radially, characterized in that each inner wall is fully covered with a corrosion-resistant coating (). Preferred application to heat exchangers based on carbon steel or stainless steel.
