An iron-nickel alloy comprising 25 to 50 wt% of nickel, 0.001 to 0.1 wt% of carbon, 0.01 to 6 wt% of at least one element selected from among groups IVa and Va elements, such as niobium or tantalum, and the balance comprising substantially iron and inevitable impurities. This alloy contains particles containing carbides including those of groups IVa and Va elements finely and uniformly dispersed in the alloy structure, thus improving mechanical strengths, thermal resistance and other properties, enhancing punchability, and reducing gas release in a vacuum. <IMAGE> |
