A nickel alloy is a type of metal made primarily from nickel combined with other elements, such as copper, chromium, or molybdenum. These alloys are known for their excellent resistance to corrosion, high temperatures, and mechanical stress, making them suitable for various industrial applications. Nickel alloys are commonly used in industries like aerospace, chemical processing, and marine engineering. Their unique properties allow them to perform well in harsh environments, such as those found in gas turbines or oil rigs. This versatility makes nickel alloys essential materials in modern engineering and manufacturing.
