What is Nimonic 90 Bars and Rods?

**Nimonic 90 Bars and Rods** are produced from a nickel-chromium-cobalt alloy with minor additions of titanium and aluminum. This combination offers superior high-temperature strength, oxidation resistance, and creep resistance. The alloy normally contains approximately 57% nickel, 18–21% chromium, and 15–21% cobalt. Nimonic 90 provides tensile properties in excess of 1000 MPa and retains its mechanical integrity at temperatures of up to 950°C. In addition, it possesses satisfactory fatigue and resistance to thermal shock, ideal for parts subject to cyclic stress as well as intense heat in high-performance applications.
