Nickel-based Alloys

Hi-Tech Manufacturing, LLC - 
Experts at Machining Nickel-based Alloys

Hi-Tech Manufacturing and its subsidiary Global Contract Manufacturing (GCM) have extensive experience and expertise in machining nickel-based alloys (e.g., Inconel® alloys).

From small to large components, prototype runs to long run production orders, we have the experience to machine nickel-based alloy components to your exact requirements.

Technical data

Nickel-based alloys offer a combination of strength, tolerance to extreme temperatures, and resistance to corrosion and oxidation. Depending on the specific
alloy, acceptable surface temperatures range from cryogenic levels to as high as 1800°F (982°C).

Applications

Nickel-based alloys are typically used in extreme environment applications, including the energy sector, due to their high strength and corrosion resistance. In the aerospace industry, nickel-based alloys are used for components such as gas turbine blades, seals and combustors, and turbocharger rotors. Other applications include high-temperature fasteners, chemical processing and pressure vessels, heat exchanger tubing, and steam generators used in nuclear pressurized water reactors.

Machining nickel-based alloys

Machining nickel-based alloys requires expertise and a thorough understanding of their properties. Traditional techniques utilizing high pressures can result in a stressed work-hardened layer of deformed metal on the surface of the component, making machining laborious. Hi-Tech Manufacturing has the expertise and capabilities to machine age-hardened nickel-based alloys, such as alloy 718, and solution-annealed alloys. We use techniques that avoid stresses and excessive
work hardening during machining, and in the case of solution-annealed alloys we perform the final steps after allowing the alloy to stabilize.

Hi-Tech Manufacturing offers the latest in cutting technologies, including new reinforced ceramic cutters that can be used to machine nickel-based alloys such as Inconel® up to 8 times faster than traditional carbide cutters.

We work with all grades of Inconel®

A sample of the nickel-based alloys we work with:

  • Inconel® 718 nickel-chromium UNS N07718 (solution-annealed and age-hardened condition)
  • Inconel® 600 nickel-chromium-iron UNS N06600 (solution-annealed)
  • Inconel® 625 nickel-chromium UNS N06625 (solution-annealed)

Inconel® is a registered trademark of Special Metals Corporation
