Summary

Inconel is a high-temperature nickel-based superalloy, with excellent mechanical properties, a high working temperature, and better resistance against both corrosion and oxidation than other metals with similar characteristics. While it requires specific machining strategy to manufacture precision components in a cost-effective manner, Inconel can be used in components with extremely complex geometries and tight tolerances. At Mindrum Precision, we manufacture Inconel components on a constant basis for multiple industries, and our expertise with the material allows us to produce some of the most difficult components manufactured today. Click here for our contact information or to request a quote, and we will show you why more engineers are trusting us with their mission-critical needs.

Applications

Inconel is used in many industries, including aerospace, defense, automotive, nuclear, submarine, and many others. It is frequently used in temperature-intensive space-based applications, and Inconel parts are incorporated into many space programs in a myriad of ways. As a versatile material, the beneficial characteristics of Inconel offset the increase in material and manufacturing cost, and the proportion of its use is steadily increasing as time goes on.
