When 3% aluminum is added to the MONEL alloy Monel K500, the material has high tensile strength and is often used for valve stem, pump shaft, etc.
with better heat resistance and corrosion resistance and long-term tissue stability. are mainly used to manufacture turbine blades and gas turbine blades with working temperature below 750℃ on aero-engine; domestic has been used on aero-engine for parts such as one or two turbine disks, free turbine disks, etc.

Monel K500 corrosion properties
|
Medium |
|
Monel K500 the corrosion resistance to non-oxidative acids, especially hydrofluoric acid, is very good, all concentrations of hydrofluoric acid can be used at room temperature, in the concentration of 10% hydrofluoric acid can use boiling point. |
|
Monel K500 also have good corrosion resistance to hot concentrated alkali, but not pure nickel. Resistant to sea water, low concentration of hydrochloric acid and various organic substances |
|
Monel K500 corrosion resistant to oxidizing acids and other strongly oxidizing solutions, molten salts, molten metals and high temperature sulfur-containing gases. |
