Nickel and Its Alloys
Nickel and its alloys are materials with excellent corrosion resistance, high-temperature resistance, and strength, making them widely used in precision casting. Nickel alloys offer excellent oxidation resistance, wear resistance, and superior mechanical properties, enabling stable operation in extreme environments. Therefore, they are often used in the manufacture of components requiring high performance and reliability, particularly in the aerospace, chemical equipment, and energy sectors.
In precision casting, nickel and its alloys are primarily used to produce critical components subjected to high-temperature environments, such as turbine blades, gas turbine components, and engine parts. Common casting processes include investment casting and sand casting, both of which ensure the high precision and complex shapes of nickel alloy components. The key advantages of nickel alloys include their exceptional high-temperature resistance, strength, and excellent corrosion resistance, making them particularly suitable for high-end applications requiring long-term exposure to high temperatures and chemical corrosion.
