Inconel® CNC Machining

As a superalloy, Inconel contains a high nickel content with exceptional resistance to corrosion and oxidation. Inconel® is also an ideal metal for high-temperature applications where resistance to extreme environments is non-negotiable. Used in components all over an aircraft, and in many other industries, Inconel® is an expensive metal, known for its difficult machinability, but Miller CNC has developed the proper methods to efficiently and reliably procure and machine it.

Types of Inconel for Precision Machined Parts

Miller CNC works primarily with 2 types of Inconel: Inconel® 625 and Inconel® 718. Most of the Inconel® parts we have manufactured include internal engine components that require tight tolerances and often times threaded features. Many of the components we manufacture require tight extremely fine surface finish results in order to maintain sealing surfaces or other critical-to-function features. We have developed methods to meet or exceed even the most critical demands.

Inconel® 625

While exhibiting high strength, high-temperature and corrosion-resistance, Inconel® 625 has many characteristics needed for aerospace applications, so it’s used extensively. Components range from shims to fasteners and from bulkheads to fluid valves and manifolds. Inconel® 625 isn’t limited to only aerospace applications and is used frequently in other industries such as Defense, Oil & Gas, Alternative Energy, Cryogenics and many more.  

Inconel® 718

Widely used for jet engine components, Inconel® 718 is another nickel alloy used extensively in industry. Similar to Inconel® 625 with its mechanical properties, Inconel® 718 is capable of age hardening. As such, Inconel® 718 is often times better suited for specific applications as compared to Inconel® 625, but is more difficult to machine (particularly in the AMS 5663 hardened condition). Components range from inlet/outlet flanges to fuel injectors and many turbine components.

The Miller CNC Inconel Machining Difference

Specializing in hard metal machining, Miller CNC has built our business around working with difficult to machine materials such as Inconel®. Historically, up to 50%-60% of the materials we purchase are Inconel materials. Through our vendor relationships and internal processes, we have established standards that have provided us with extensive cost knowledge regarding Inconel machining. This allows us to provide accurate, reliable quotes for all your Inconel component projects.
