Abstract
A fin and a tube for a high-temperature heat exchanger are made of a nickel-based alloy which contains 2.0 to 5.0% of Al and further contains, as required, at least one selected from the group consisting of 0.1 to 2.5% of Si, 0.8 to 4.0% of Cr, and 0.1 to 1.5% of Mn, the balance being Ni and unavoidable impurities.
