Basic information:
Iron-nickel-cobalt alloy is an important structural material with the following main properties:
High strength: Iron-nickel-cobalt alloys have good strength and hardness, and can withstand large forces and strains without deformation or fracture.
Corrosion resistance: Due to the presence of corrosion-resistant elements such as nickel and cobalt, iron nickel cobalt alloys have good corrosion resistance and are suitable for working in harsh environments such as high temperatures, high pressures and corrosive media.
Good thermal stability: Iron-nickel-cobalt alloys can still maintain good mechanical properties at high temperatures, suitable for use in high-temperature working environments.
Magnetic properties: Due to the presence of magnetic elements such as iron and nickel, Iron-Nickel-Cobalt alloys are usually magnetic and are suitable for magnetic applications.
