Nimonic 75 Sheets | UNS N06075 Heat-Resistant Superalloy Sheets
When a leading aerospace OEM faced frequent failures of turbine blades due to creep and oxidation at temperatures exceeding 900°C, the upgrade to Nimonic 75 Sheets (UNS N06075) transformed reliability. Known for its outstanding strength and resistance to thermal creep, oxidation, and corrosion, Nimonic 75 has become the go-to material for aerospace gas turbines, chemical reactors, marine turbines, and power generation equipment demanding extended life in harsh environments.
Table of Contents:
Nimonic 75 is a nickel-chromium-cobalt alloy with additions of titanium and aluminum that create a precipitation-hardened microstructure, giving outstanding mechanical strength and stability from cryogenic temperatures up to 980°C. This alloy greatly outperforms conventional stainless steels and earlier nickel alloys by maintaining tensile strengths exceeding 900 MPa and creep resistance over prolonged high-temperature exposure.
Compared to other superalloys, Nimonic 75 offers excellent weldability, oxidation resistance, and thermal fatigue resistance, which enable its use not only in highly stressed turbine components but also in chemical process vessels, marine exhaust systems, and power station heat exchangers. Aurico Alloys LLP stocks and supplies these sheets with full traceability and mill certification, supporting industries with quick delivery and custom sizing needs.
Aurico Alloys LLP is your trusted partner as a supplier, manufacturer, stockist, and exporter of Nimonic 75 Sheets serving chemical, oil & gas, marine, pharma, and power generation sectors with affordable pricing, comprehensive stock, and global dispatch capabilities.

Applications & Benefits
Why this grade
Nimonic 75 is an 80/20 nickel-chromium alloy with titanium stabilisation, and it is solid-solution strengthened only — it cannot be significantly age-hardened. That is precisely why it is chosen: it forms and welds readily with no solution-treat-and-age cycle and no strain-age cracking risk, which makes it the sheet-metal grade for gas turbine combustion hardware, furnace parts and heat-treatment fixtures.
- Aerospace & Gas Turbines: Compressor blades, turbine discs, and casings requiring high strength and thermal stability.
- Chemical Industry: High-temperature reactors, heat exchangers, and pressure vessels with corrosive atmospheres.
- Marine Industry: Turbine housings and exhaust components operating in corrosive marine environments.
- Power Generation: Boiler components, heat exchangers, and steam turbine parts in harsh thermal and mechanical conditions.
- Fabricators & Suppliers: Precision sheets, thin gauge shim stock, and custom cut-to-size plates supporting OEMs and service shops worldwide.
