Precision CNC Inconel Machining Services

As a superalloy, Inconel® contains a high nickel content and exhibits exceptional corrosion and oxidation resistance. Inconel is ideal for high-temperature applications requiring extreme resistance to harsh environments. Known for its difficult machinability, Inconel is an expensive metal for component fabrication. Miller CNC has proudly developed the best Inconel procurement methods, and our modern equipment can reliably machine Inconel alloys efficiently and without waste.

To find the best Inconel solutions for your applications, contact Miller CNC today, and an expert will help determine the right Inconel components for your needs.

What is Inconel?

Inconel is a nickel-based superalloy with excellent durability and benefits. There are a variety of Inconel alloys with similar yet unique properties, however, Inconel’s general nickel-based composition offers a host of benefits for machined parts. Inconel is highly resistant to oxidation, corrosion, intense heat, and dramatic pressure changes. These features make Inconel components highly versatile and able to be used in even the most extreme industrial environments.

Is Inconel Difficult to Machine?

While Inconel offers numerous benefits, these features can create complications during machining. Inconel alloys have high work-hardening rates, making the already durable Inconel even stronger as it is machined. Its strength can pose a challenge to machining efforts by deflecting workpieces, generating intense heat, or straining cutting tools. Miller CNC has developed specialty Inconel machining services, allowing us to successfully machine Inconel alloys to your specific demands.

What is the Machinability Rating of Inconel?

The AISI Machinability Index lists various machinability ratings for different metal alloys. Metals with 100% machinability ratings are soft and the easiest to machine, while metals with low ratings are harder materials and more difficult to machine. While different alloys vary in their ratings, generally, Inconel alloys have machinability ratings between 9% and 16%. Although Inconel is highly difficult to machine, Miller CNC has developed advanced CNC machining services to create precision Inconel components.

Types of Inconel for CNC Machining by Miller CNC

Miller CNC works primarily with Inconel alloys 625 and 718. Our Inconel-machined components feature extremely fine surface finishes and tight tolerances for applications requiring critical-to-function features. We have perfected our services to meet or exceed even the most critical demands.

Why Choose Inconel?

When comparing Inconel 625 versus Inconel 718, it is important to recognize their similarities and differences. These Inconel alloys offer various benefits for specific projects. Talk to an expert at CNC Miller for help determining the best Inconel alloy for your application.

Inconel 625 Advantages & Applications

Inconel 625 exhibits strength, high-temperature tolerance, and excellent corrosion resistance. This alloy is ideal for demanding environments and can withstand exposure to salt water, fresh water, air, alkaline chemicals, and intense temperatures. Inconel 625 is often used to machine components for aerospace applications, with parts including bulkheads, fluid valves, manifolds, and more.

Inconel 718 Advantages & Applications

Widely used for jet engine components, Inconel 718 is often found in the aerospace and cryogenics industries. With similar mechanical properties as Inconel 625, Inconel 718 is also capable of age hardening. As such, it is often better suited for high-stress applications, however, it is more difficult to machine―particularly the AMS 5663 hardened condition. Components made from Inconel 718 range from inlet and outlet flanges to fuel injectors and many turbine components.
