Construction

Rotor Rings

Made from Paragon’s CM-250 high-carbon cast iron, the rotor rings are heat-treated to prevent internal stress and cracking under load. CBN precision machining ensures a flat surface for consistent braking and reduced vibration.

Aluminium Hats

The rotor hats are CNC-machined from aerospace-grade 6061-T6 aluminium and hard anodised to MIL-A-8625 Type III spec for maximum durability. Material is strategically removed to reduce weight while maintaining strength under high loads.
