Superalloys are widely used in the aerospace industry due to their outstanding strength, oxidation resistance, and stability at elevated temperatures. They are essential for critical engine components such as turbine blades, disks, shafts, and combustion chambers.
However, these same properties make superalloys extremely difficult to machine, resulting in rapid tool wear, high cutting temperatures, and poor surface finish if improper tools are used.
To address these challenges, Moresuperhard provides advanced CBN cutting tools and coated carbide tools specially designed for efficient and precise machining of superalloys.

Superalloys are generally divided into nickel-based, cobalt-based, and iron-based categories, each used for different aircraft components:
Nickel-Based Superalloys (Inconel 718, Rene 80, Inconel 625)
→ Turbine blades, disks, shafts, and exhaust components
Cobalt-Based Superalloys (Stellite 6, Haynes 188)
→ Turbine nozzles, sealing rings, and bearings
Iron-Based Superalloys (A286, Incoloy 901)
→ Casings, bolts, and structural parts
These materials must withstand continuous exposure to temperatures exceeding 700–1000°C, making tool performance and thermal stability critical in machining

Superalloys present multiple difficulties during cutting and grinding:
High strength and work hardening, leading to high cutting forces
Low thermal conductivity, causing excessive heat concentration
Strong chemical affinity, resulting in built-up edges
Abrasive carbides, which accelerate tool wear
These factors require tools with excellent hardness, wear resistance, and heat resistance.
Moresuperhard offers specialized cutting tools that ensure high productivity, precision, and tool life when machining aerospace-grade superalloys:
Ideal for hard turning and finishing of nickel-based superalloys
Outstanding thermal stability and wear resistance
Capable of maintaining dimensional accuracy even under high cutting temperatures
