Nimonic 115 Strip

Product Details

A precipitation-hardenable nickel-chromiumcobalt alloy with an addition of molybdenum for solid-solution strengthening. It is similar to NIMONIC alloy 105 but has higher levels of aluminum and titanium for increased strengthening by precipitation hardening. The alloy has high strength and creep resistance at temperatures to about 1850°F (1010°C). Used for turbine blades in aircraft gas turbines.

STANDARD PRODUCT FORMS
Round and extruded section.
