Abstract

The invention discloses a corrosion-resistant liquid-state amplitude-modulated decomposition type nickel alloy for a ship power system condenser. The corrosion-resistant liquid-state amplitude-modulated decomposition type nickel alloy consists of the following components in percentage by weight: 1.2-1.8wt% of In, 2.0-3.5wt% of Ag, 2.0-3.0wt% of Bi, 1.0-1.5wt% of Pb, 3.0-5.0wt% of Fe, 1.5-1.8wt% ofSb, 0.2-0.4wt% of Sm, 4.0-6.0wt% of Al and the balance of nickel. The material provides a technical scheme different from the copper alloy for the corrosion-resistant liquid-state amplitude-modulateddecomposition type nickel alloy for the ship power system condenser. The alloy can be implemented and industrialized to greatly promote updating needs and commercial upgrading needs of the novel corrosion resistant material, under an extremely corrosion environment, in the national ship industry.
