Industrial Ceramic Nut
Industrial ceramic nut usually made of materials such as zirconia, alumina, and silicon nitride, which have relatively stable physical and chemical properties. Physical stability mainly manifests in aspects such as resistance to high and low temperatures, insulation, anti-magnetism, and wear resistance; chemical stability mainly lies in corrosion resistance and oxidation resistance.
Physical stability of Industrial ceramic nut:
1.High and low temperature characteristics: They do not deform or elongate at high temperatures (800°C) and do not reduce connection strength. They can maintain good connection strength even at -70°C.
2.Insulation characteristics: Zirconia ceramic nut can maintain good insulation at room temperature. The room temperature resistivity is 10, and when heated to a certain temperature range (above 800°C) in the air, they can change from insulators to conductors.
3.Anti-magnetic characteristics: Both zirconia and alumina nut can resist magnetism under normal conditions.
4.Wear resistance characteristics: Their extremely high hardness (Mohs 9) allows them to maintain their original shape and not be worn down or altered in shape under continuous friction.
5.Chemical stability:
Corrosion resistance: Zirconia ceramics do not react chemically with strong acids or strong bases. However, they may age in high-temperature (above 200°C) steam environments.
6.Oxidation resistance: Zirconia ceramics have good properties of not allowing gases such as oxygen and liquid metals like steel to penetrate, and are widely used in high-temperature fuel cells, oxygen gas sensors, and liquid metal oxygen sensors.
Application of industrial ceramic nut:
Industrial ceramic nut has excellent properties such as high temperature resistance, insulation, non-magnetism, corrosion resistance, environmental friendliness, and aesthetic appeal. They can not only rival traditional plastic and metal screws but also have seen continuous performance improvements in recent years, with their application fields expanding. They are increasingly replacing traditional screws in certain areas.
1) Aerospace industry (insulation and anti-interference for electronic equipment)
2) Electronics industry (insulation, anti-interference, and light weight)
3) Medical device industry (insulation, non-magnetism, environmental friendliness, and anti-interference, making medical equipment safer to use)
4) Petrochemical industry (high temperature resistance, chemical resistance, and corrosion resistance, extending equipment lifespan)
5) Communication industry (insulation, non-magnetism, and safety)
6) Shipbuilding industry (acid resistance, alkali resistance, and corrosion resistance, extending service life).
Industrial ceramic nut has the following advantages compared with metal nut:
1.Strong corrosion resistance: It has strong resistance to chemicals and are not easily affected by them, making them suitable for special environments.
2.Light weight: Industrial Ceramic nut have a low density and are light, weighing about half as much as iron, one-third as much as aluminum, and half as much as magnesium.
3.Good insulation:It has excellent electrical insulation properties and are resistant to electric arcs, thus they are widely used in electrical equipment.
4.High strength at high temperatures: The strength and hardness of ceramic nut at high temperatures are greater than those of metals, and they can maintain their mechanical properties under high-temperature conditions.
5.Low friction coefficient: ceramic nut has a low friction coefficient and good self-lubricating properties, do not stick or seize, and therefore perform well in high-speed moving parts.
6.Non-magnetic: Ceramic nuts are non-magnetic and are suitable for special working environments, such as in nuclear magnetic resonance instruments.
Good biocompatibility: Ceramic nuts have no toxic reactions to human tissues, do not dissolve, do not contaminate body fluids, and have good biocompatibility, thus they are used in the medical field.
