Construction

Rotor Rings

Paragon rotor rings are cast from CM-250 high-carbon alloy and heat-treated to prevent internal stress. CBN precision machining ensures even pad contact, reduced vibration, and reliable braking under load.

Aluminium Hats

The hats are CNC-machined from aerospace-grade 6061-T6 aluminium, then hard anodised to MIL-A-8625 Type III specification for maximum corrosion resistance and strength. Excess material is removed to lower weight without compromising integrity.
