Aircraft Brake Discs

Aircraft brake discs are critical components in the braking systems of modern aircraft, ensuring safe and efficient deceleration during landing and taxiing. These discs are typically manufactured from high-strength carbon composites or heat-resistant alloys to endure the extreme friction and temperature conditions generated during braking. The production of aircraft brake discs involves advanced machining techniques and strict quality control processes to guarantee their durability, thermal stability, and performance reliability under heavy load and high-speed conditions.
