1. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
2. High precision dimensional tolerance with diamond polished surface quality
3. Extreme wear and abrasion resistance., over 276 times in comparison with stainless steel
4. Extraordinary electrical insulation, it always us in many high voltage, high-current application
5. Chemical corrosion resistance under high temperature, even if with strong acid or alkali
6. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
7. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.
8. Low material cost in high-level applications than other technical ceramics
