Waspaloy vs Inconel: What’s the Difference

Waspaloy vs Inconel

If you are looking for a high-performance metal alloy, consider two of the most popular options: waspaloy and inconel. Both alloys are suitable for extreme environments and can be used in various applications. But if you’re trying to decide which alloy suits your project, it’s essential to understand their differences. Let’s take a closer look at these two alloys so that you can make an informed decision.

Differences between Waspaloy and Inconel

The first difference between waspaloy and Inconel lies in their composition. Waspaloy is an alloy of nickel, cobalt, chromium, and molybdenum, while Inconel is an alloy of nickel, chromium, iron, and molybdenum. This difference in composition means that the two metals have different properties when exposed to other conditions. For example, waspaloy has higher tensile strength than inconel but cannot withstand as high temperatures as inconel can.

Additionally, the melting points of these two alloys vary significantly. Waspaloy has a melting point of 1375°C (2510°F), while inconel has a melting point of 1413°C (2575°F). This difference in melting points means that waspaloy must be heated more quickly than inconel to reach its melting point. This can be beneficial if a hot process needs to occur quickly or if limited time is available for processing the material.

On the other hand, one benefit of working with inconel is its ability to resist corrosion better than waspaloy due to its higher chromium content. Inconel retains its strength even after being exposed to extremely high temperatures, whereas waspaloy loses strength at temperatures over 1000℃ (1832℉). These factors make inconel preferable when working with materials exposed to extreme heat or corrosive media such as acids or saltwater.

  • Waspaloy is an age-hardenable superalloy that offers high strength and corrosion resistance.
  • Inconel is a nickel-chromium alloy that offers high strength and corrosion resistance.
  • Waspaloy is typically used in aerospace applications, while Inconel is typically used in chemical processing applications.
  • Inconel has a higher melting point than Wasploy, making it ideal for high-temperature applications.
  • Inconel is more resistant to chloride ion corrosion than Waspaloy, making it ideal for chemical processing applications.


Comparing waspaloy versus inconel can help determine which metal alloy suits your project or application needs. While both alloys are suitable for extreme environments, each has unique properties that make it better suited for specific applications than others. By understanding the differences between these two metals—such as their composition, tensile strength, and melting points—you can ensure that you choose the best alloy for your project’s needs.
