NIMONIC 115

NIMONIC ALLOY 105

category：

Product Description

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.
