Inconel 718 Foil
Inconel 718 foil is a nickel-chromium alloy with superior mechanical performance, oxidation and high temperature characteristics. While about 90 % of cobalt alloys are used in high performance applications because of their strength, toughness and wear resistance, this specific alloy is applied where corrosion and oxidation resistant characteristics are crucial. Inconel 718 is widely used in aerospace applications, power generation, and chemical processing. The foil type of Inconel 718 is easily adapted to thin and elastic material for applications that demand such metal.

Advantages of Nickel 718 Foil
These flexible Foil fittings offer numerous benefits for various industrial applications.
- Superior Oxidation and Corrosion Resistance: The alloy resists well oxidation and corrosion threats and can sustain the worst and harshest threats, such as the attacks by acids, salts and high temperatures.
- Good Fatigue Resistance: Fatigue strength: Inconel 718 has a great fatigue strength that is very important for parts that undergo cyclic stresses and high stress levels.
- High Creep-Resistant: The foil shows excellent creep resistance and preserves its geometry and its dimension in high-temperature stress.
- Good Weldability: Inconel 718 has good weldability hence, several welding processes can be employed during the fabrication of the material.
- Non-Magnetic: The alloy is non-magnetic, meaning it does not interfere with magnetic fields; hence, it could be useful in situations where magnetic fields cannot be allowed.
- Excellent Ductility: Being a foil material, Inconel 718 exhibits good ductility and formability and can thus be easily formed and bent into the desired forms and shapes.
- Heat-Resistant: The foil stays ductile and does not change its mechanical characteristics. It is also protected from oxidation at high temperatures, which is important for the components operating at high temperatures.
