Nimonic 75 Nickel Sheet: High-Temperature Performance You Can Rely On
At ZYTC Alloy, we are proud to announce the successful completion of an export order of Nimonic 75 nickel sheet to a valued customer in Turkey. The order consisted of Nimonic 75 nickel sheet measuring 1.6mm × 1000mm × 2000mm, produced strictly in accordance with BS 2HR 203-2009 standard. Through our rigorous, standardized, process-driven, and professional production and inspection protocols, every piece of Nimonic 75 material was thoroughly tested and qualified before delivery.
Nimonic 75 is a nickel-chromium superalloy that has been a cornerstone of high-temperature engineering since its introduction in the 1940s for turbine blades in the prototype Whittle jet engines. Today, Nimonic 75 continues to serve critical roles in gas turbine engineering, aerospace manufacturing, industrial thermal processing, furnace components, and nuclear engineering. As a Nimonic 75 supplier with deep expertise, ZYTC Alloy delivers Nimonic 75 in all product forms – sheet, strip, wire, bar, tube, forging, and plate – and offers custom fabrication to drawings, strictly following ASTM, EN, and AMS standards.
Chemical Composition of Nimonic 75
The exceptional performance of Nimonic 75 derives from its well-balanced chemical composition. Nimonic 75 is an 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. The table below presents the detailed chemical composition of Nimonic 75:
| Element | Content (%) |
|---|---|
| Nickel (Ni) | Balance (approx. 72% min) |
| Chromium (Cr) | 18.0 – 21.0 |
| Titanium (Ti) | 0.20 – 0.60 |
| Carbon (C) | 0.08 – 0.15 |
| Iron (Fe) | 5.00 max |
| Manganese (Mn) | 1.00 max |
| Silicon (Si) | 1.00 max |
| Copper (Cu) | 0.50 max |
| Cobalt (Co) | 5.00 max |
| Aluminum (Al) | 0.40 max |
The high nickel content provides exceptional mechanical stability and toughness, while the chromium content (18-21%) delivers excellent oxidation and corrosion resistance at elevated temperatures. The carefully controlled addition of titanium and carbon further enhances the alloy‘s strength and creep resistance, making Nimonic 75 uniquely suited for demanding high-temperature environments.

Nimonic 75 is most commonly used for sheet-metal fabrications that require oxidation and scaling resistance coupled with medium strength at high operating temperatures. The alloy is readily fabricated and welded, making it highly versatile for custom-engineered components.
Fabrication and Processing of Nimonic 75
Nimonic 75 exhibits excellent fabricability. The alloy can be hot worked at temperature ranges of 1220–950°C and hot forged at 982–1204°C. Cold working may also be performed, followed by annealing at 1051°C (1925°F) with air cooling. For welding, Nimonic 75 can be joined using common techniques such as manual metal arc welding, tungsten inert gas (TIG) welding, and metal inert gas (MIG) welding with matching filler metal. Gas tungsten arc welding (GTAW) studies on thin Nimonic 75 sheets of 1.6mm thickness have been successfully carried out.
