A primary surface recuperator is made from a plurality of components, one of such components being a primary surface sheets. The primary surface sheet is used to transfers heat from a donor fluid on a donor side to a recipient fluid on a recipient side. And to increase the efficiency of this transfer, the primary surface sheet is made from a very thin material. Thus, as the primary surface recuperator cycles, the temperature of the primary surface sheet increases in temperature and decreases in temperature during the cycling. This results in the primary surface sheet experiencing a high degree of thermal deformation. To compensate for the thermal deformation a first portion of the primary surface sheet has a preestablished thermal deformation characteristic, the preestablished thermal deformation characteristic including a resistance to high temperature deformation and a high temperature resistance to corrosion and a second sheet portion has a preestablished thermal deformation characteristic being less than the resistance to high temperature deformation and the high temperature resistance to corrosion than that of the first sheet portion are attached to form the primary surface sheet.
