It is a high-precision reference instrument that uses alumina ceramics.
● It has excellent hardness and wear resistance, allowing for long-term use.
● It has high rigidity and is resistant to changes in load, resulting in minimal aging changes and the ability to maintain high precision over a long period.
● Its low specific gravity allows for weight reduction, making it a manageable material.
● It has excellent corrosion resistance, preventing oxidation and corrosion.
● Its thermal expansion coefficient is excellent, resulting in very little deformation due to temperature changes.
