Nickel 200 / 201 are commercially pure nickel alloys known for excellent resistance to corrosion, outstanding thermal and electrical conductivity, and superior mechanical properties in non-oxidizing environments. These alloys exhibit high ductility, excellent formability, and good weldability, making them suitable for a wide range of industrial applications. Nickel 201 offers improved resistance to embrittlement at elevated temperatures due to its lower carbon content, making it ideal for high-temperature service. Nickel 200 / 201 retain their performance in chemically aggressive environments, making them widely used in chemical processing equipment, heat exchangers, food processing systems, electrical and electronic components, and aerospace applications where purity, reliability, and corrosion resistance are essential.
