NIMONIC® Alloy 75

The alloy with good mechanical properties and resistance to oxidation at high temperatures.

Applications:
production of thin sheets for gas turbine engines, elements of industrial furnaces, equipment and equipment for heat treatment, and in nuclear technology.

Density
g/cm3 8.37
lb/in3 0.302

NIMONIC® Alloy 80A

NIMONIC® Alloy 80A is similar to NIMONIC Alloy 75 but made precipitation hardenable by additions of aluminium and titanium. This alloy has good corrosion and oxidation resistance as well as high tensile and creep strength at temperatures up to 815 °C (1500 °F).

Applications:
parts of gas turbines, bolts, supply pipes in nuclear steam generators, dies and casting cores, exhaust valves for internal combustion engines.

Density
g/cm3 8.19
lb/in3 0.296

NIMONIC® Alloy 90

Nimonic Alloy 90 is a precipitation hardenable alloy with a high stress rupture strength and creep-resistant at temperatures to 920°C. It has good resistance to corrosion and oxidation at high temperatures.

Applications:
gas turbine blades, hot working tools, springs.

Density
g/cm3 8.18
lb/in3 0.296

NIMONIC® Alloy 263

Hardened alloy with the addition of molybdenum for permanent reinforcement. It has high strength and corrosion resistance along with good plasticity in welded structures at high temperatures. This alloy is particularly suitable for the production of sheet metal. Used in gas turbines for rings, housing and various artificial sheets.

Density
g/cm3 8.36
lb/in3 0.302

NIMONIC® Alloy PK33

The alloy is hardened and has a relatively high (7%) molybdenum content for reinforcement. It contains a unique combination of high temperature strength, creep resistance and ductility during welding. This alloy is particularly suitable for welded sheet structures. Used in gas turbines for fires and other components.

Density
g/cm3 8.21
lb/in3 0.297
