Photo Etched Inconel 625 in the Aerospace Industry

Since Inconel 625 was introduced in the 1960s, engineers have discovered countless applications for the superalloy. From seawater to chemical processing, Inconel 625 provides innovative and sturdy solutions to the toughest engineering challenges.

In this post, we'll focus on Inconel 625's applications in the aerospace industry and give you an overview of how engineers are using the superalloy to create more efficient aerospace components.

What is Inconel 625?

Inconel 625 is a superalloy introduced in the 1960s for steam piping applications.

Since its introduction, applications using Inconel 625 have multiplied as more industries seek materials with high strength, high temperature thresholds and corrosion resistance.

Why is Inconel 625 Ideal for Aerospace?

As mentioned above, there are three properties that regularly attract aerospace engineers to the material:

  1. High temperature threshold
  2. Corrosion and oxidation resistance
  3. High strength

Inconel 625 can endure a wide-range of temperatures while retaining considerable strength. It has shown sustained strength from temperatures ranging from cryogenic to nearly 2000°F (1093°C).

These properties allow engineers to build stronger components that can endure higher temperatures and more extreme conditions without sacrificing material stability.

Aerospace Applications Using Inconel 625

Inconel 625's ability to endure high temperatures while maintaining its strength makes it useful in several aerospace applications.

It is regularly employed in various high temperature components, including:

  • Exhaust systems
  • Engines
  • Heat exchangers
  • Fuel cells

The use of superalloys like Inconel 625 in jet engines has helped engineers continue to improve fuel efficiency since they can now build engines that endure increasingly higher temperatures.

The Challenges of Etching Inconel 625

While Inconel 625’s resistance to corrosion makes it an ideal alloy for numerous applications, it makes etching the material very difficult.

That is why many photo etching companies do not even etch the material.
