Silicon nitride ceramic screws and nuts

Features

1. High strength: Bending strength can reach over 800 MPa, far exceeding traditional ceramic materials, and can withstand high loads.
2. High hardness: Mohs hardness is second only to superhard materials such as diamond and cubic boron nitride, offering excellent wear resistance.
3. High temperature resistance: Can operate stably at high temperatures up to 1600°C, and mechanical strength is still maintained at 1200°C.
4. Corrosion resistance: Resistant to most inorganic acids (except hydrofluoric acid) and sodium hydroxide solutions below 30%, as well as many organic acids.
5. Low thermal expansion coefficient: Approximately 20% of that of 45# steel, providing good dimensional stability in environments with large temperature variations.
6. Insulation performance: Possesses excellent electrical insulation properties, suitable for electrical equipment applications.
