Introduction:

Nimonic 90 wire is a high temperature alloy wire, also known as Nimonic 90. It is a nickel-based alloy wire with excellent high temperature strength, corrosion resistance and oxidation resistance.

The main components of Nimonic 90 wire include elements such as nickel (Ni), chromium (Cr), cobalt (Co), iron (Fe) and copper (Cu). It has high temperature stability and is able to maintain excellent mechanical properties and corrosion resistance in high temperature environments. In addition, it also has good antioxidant properties and can remain stable in high temperature oxidation environments.

Nimonic 90 wire is machinable and can be processed and formed by heat treatment, cold working and welding. Its high temperature strength, corrosion resistance and oxidation resistance make it an ideal material choice for high temperatures and extreme environments. Whether in the aerospace, energy or chemical industries, Nimonic 90 filaments demonstrate superior performance and reliability.
