Are you searching for a reliable, quick-turn supplier of precision Superalloy CNC machining parts?
Prem Fixer delivers high-performance machining solutions engineered for extreme environments. Leveraging advanced technology, specialized expertise, and stringent material handling protocols, we manufacture components that meet the most demanding operational standards. With over 15 years of experience in custom superalloy CNC machining, we ensure your project requirements are met with exceptional precision, quality, and competitive pricing.


Superalloys are engineered to thrive under extreme heat and high-stress conditions, making them indispensable for Aerospace, Automotive (Turbochargers), and Energy (Gas Turbines). Due to their exceptional hardness, these materials require specialized expertise to machine.
PremFixer specializes in Superalloy CNC Machining, providing the precision needed to produce components with ultra-tight tolerances and complex geometries. From Inconel and Hastelloy to Cobalt-based alloys, we deliver high-performance parts that meet the most rigorous industry standards.
Retains mechanical strength at elevated temperatures, which is usually could exceeding 1,000°C (1,800°F).
Resists degradation in harsh environments, crucial for aerospace and power generation applications.
Prevents deformation under constant stress at high temperatures over extended periods.
High fatigue resistance ensures that the material doesn’t crack or fail due to the repeated stresses it encounters during operation.
Superalloys are the backbone of extreme-environment engineering. At PremFixer, we specialize in the precision CNC machining of the three primary categories: Nickel-based, Cobalt-based, and Iron-based superalloys
To help you choose the ideal material for your project, we have prepared a comprehensive guide detailing the properties of popular grades like Inconel 718, Hastelloy, and Haynes. Explore the unique applications and critical performance differences between these heat-resistant alloys below.
| Types | Composition | Properties | Applications | Examples |
|---|---|---|---|---|
| Nickel-Based Superalloys | A nickel-chromium matrix optimized with alloying elements like molybdenum, tungsten, titanium, and aluminum for precipitation hardening. |
|
|
Inconel 718, Inconel 625, Hastelloy C276. |
| Cobalt-Based Superalloys | Primarily a cobalt-chromium matrix reinforced with tungsten, nickel, and carbon to form stable carbides. |
|
|
Haynes 25 (L605), Stellite 6, CoCrMo. |
| Iron-Based Superalloys | Austenitic alloys based on iron, nickel, and chromium, often enhanced with titanium or molybdenum for increased strength. |
