OptiPowder Ni625

About OptiPowder Ni625

OptiPowder Ni625 is used widely in industrial applications, typically in structural parts that require elevated operating temperatures and corrosive environments. It has an exceptional combination of strength, hardness and corrosion resistance.

Nickel superalloy 625 (UNS N06625)

Nickel superalloy 625 is a Ni-Cr-Mo-Nb-Fe solid solution alloy, eliminating precipitation hardening treatment to attain full properties. The alloy is also resistant to various corrosive media such as potable, salt, and alkaline waters and oxidizing and non-oxidizing environments.


This alloy exhibits particular resistance to stress corrosion cracking, make it ideal for marine nuclear, biogas, and waste treatment applications. Due to its high tensile, creep, rupture strength, weldability, and brazability, this alloy is used for various parts in aircraft engines.


Apart from these applications, 625 is also used for combustion and thrust chambers of rockets, engine parts of racing cars, and in various nuclear reactor components where high-temperature stability is essential.
