At Tik Precision, we specialize in the complex CNC machining requirements of the global aerospace industry. The performance of modern aircraft engines depends heavily on the materials used in their turbine sections. Nickel-based superalloys and titanium alloys dominate aerospace turbine component manufacturing because of their exceptional strength-to-weight ratio, high-temperature capability, and fatigue resistance. These same properties, however, make them notoriously difficult to machine.
Common Materials in Aerospace Turbine Components
- Nickel-based superalloys (e.g., Inconel 718): Used extensively in turbine blades, disks, and combustor components due to excellent high-temperature strength and creep resistance.
- Titanium alloys (e.g., Ti-6Al-4V): Common in compressor blades, disks, and casings where high strength-to-weight ratio is prioritized. See our Titanium CNC Machining guide for more details.
- Single-crystal castings: Used for high-pressure turbine blades where superior thermal fatigue performance is required for global aviation standards.
Why These Materials Are Difficult to Machine
- Low thermal conductivity: Heat concentrates at the cutting edge, accelerating tool wear.
- High strength retention: Alloys maintain strength even at extreme temperatures, resulting in high cutting forces.
- Work hardening: Nickel-based alloys harden rapidly, requiring precise CNC parameter control.
- Chemical reactivity: Titanium reacts with tool materials, necessitating advanced coating strategies.
