Abstract
A gas tube for an EGR cooler has such a structure that a metal plate having a flat plate shape is bent in a tube shape. The metal plate includes a core material, a sheath material clad on one surface of the core material or on both surfaces thereof, and an intermediate material clad between the core material and the sheath material so as to prevent magnesium from diffusing from the core material to the sheath material. The core material includes copper (Cu), silicon (Si), iron (Fe), magnesium (Mg), manganese (Mn), titanium (Ti), and aluminum (Al).
