The high-temperature resistance properties of nickel-chromium-copper C18000 are as follows:

• Long-term usage temperature

High-temperature resistance: The C18000 nickel-chromium-copper rod can operate stably for a long time at 500°C, and its short-term temperature resistance can reach 600°C.

• High-temperature stability

It has outstanding resistance to re-hardening softening at high temperatures, with a strength retention rate of ≥ 80%. It also has excellent creep resistance and high-temperature resistance. The C18000 nickel-chromium copper rod is suitable for applications such as high-temperature welding wheels and hot-press molds.

• Physical properties

High-temperature resistance: The melting point of C18000 nickel-chromium-copper rod is 1040℃, the thermal expansion coefficient is 17.5×10⁻⁶/℃, and the thermal conductivity is 200 W/m·K (remains stable at high temperatures).

The high-temperature resistant C18000 nickel-chromium-copper rod is enhanced by adding nickel and chromium elements, significantly improving its high-temperature oxidation resistance and corrosion resistance. It is suitable for high-temperature environments above 500℃.
