The assembly comprises a series of tubular members formed from a first metal, each of the tubular members including an end portion and a header formed from a second metal, wherein the first metal and the second metal have similar coefficients of thermal expansions. The header includes a plurality of openings extending therethrough and each of the end portions of the tubular members is mechanically secured within corresponding openings within the header to form an after-cooler assembly. A method for forming the air-to-air after-cooler assembly is also provided.
