Refractories are materials that can withstand very high temperatures – over 1200ºC and bear load at those temperatures without catastrophic failure. Among the oldest of the applications for ceramics, the refractory business of CUMI focuses on delivering built-to-design solutions for the ferrous, non-ferrous and chemical process industries.
CUMI’s refractory products are used in investment casting of super alloys for the aircraft engine turbine blade industry. CUMI offers flame deflector refractory material for rocket launch pads that can withstand high temperature from flame and gas during lift-off.
Silicon carbide thermal heat shields are also found on the underside of space re-entry vehicles to protect them from burning up on re-entry.
