Home >Nimonic 90 Bar
Boikanyo Metals is a reliable manufacturer and supplier of Nimonic 90 Bars, proudly based in Cape Town, South Africa. They specialize in high-performance materials designed to withstand extreme temperatures and high-stress situations. Nimonic 90 is a nickel-chromium-cobalt alloy that gets its strength from the addition of titanium and aluminum, making it incredibly resistant to heat, oxidation, and creep. Boikanyo’s Nimonic 90 Bars are crafted to exacting standards, ensuring they deliver superior strength, stability, and reliability for demanding applications in aerospace, power generation, and industrial settings.
These Nimonic 90 Bars are primarily made up of nickel (around 60%), chromium (about 20%), and cobalt (approximately 15%), with small amounts of titanium and aluminum added for precipitation hardening. This unique blend gives the alloy remarkable mechanical strength, fatigue resistance, and thermal stability, even at temperatures soaring up to 950°C. Plus, it boasts excellent resistance to oxidation and corrosion, especially under cyclic heating conditions.
