Nickel alloys are materials made by combining nickel with other metals, such as copper, chromium, or iron. These alloys are known for their excellent resistance to corrosion and high temperatures, making them suitable for various applications, including aerospace, chemical processing, and marine environments. The unique properties of nickel alloys, such as strength and ductility, allow them to perform well under extreme conditions. Common types of nickel alloys include Inconel and Monel, which are often used in industries that require durable and reliable materials for demanding environments.
