Abstract
A heat exchanger comprises tubular elements and fin members. The tubular elements are made of an aluminum alloy containing 0.05 to 1.0 wt % of Mg, 0.2 to 1.2 wt % of Si, 0.2 to 1.5 wt % of Mn, 0.01 to 0.5 wt % of Fe, as necessary components, and further containing at least one of 0.05 to 0.3 wt % of Cr and 0.01 to 0.05 wt % of Ti, as optional auxiliary components, and 0.05 or less wt % of Cu as a controlled impurity, the balance being aluminum and unavoidable impurities. The fin members are made of another aluminum alloy containing 0.05 to 1.0 wt % of Mg, 0.2 to 1.2 wt % of Si, 0.2 to 1.5 wt % of Mn, 0.01 to 0.5 wt % of Fe, and further containing at least one of 0.01 to 0.1 wt % of In and 0.1 to 2.0 wt % of Zn as necessary components, and still further containing at least one or of 0.05 to 0.3 wt % of Cr and 0.01 to 0.05 wt % of Ti as optional auxiliary components, and 0.05 wt % or less of Cu as a controlled impurity, the balance being aluminum and unavoidable impurities.
