Hexoloy SE exhibits strength of 2-3 times that of nitride-bonded and recrystallized SiC refractory materials. Hexoloy SE's strength is also nearly twice that of siliconized SiC and nitride bonded SiC materials. More importantly, Hexoloy SE retains its strength at temperatures of up to 1650°C (air) and up to 1900°C (inert).
