Introduction
Nickel alloys are a group of high-performance materials made primarily from nickel combined with other elements such as chromium, molybdenum, and iron. These alloys are known for their exceptional resistance to heat, corrosion, and extreme environments.
They are widely used in industries where standard materials fail, including aerospace, chemical processing, energy, and marine engineering.
