Description

For ceramic screws, you can choose screw products made of zirconia, alumina, silicon nitride and other materials. They have relatively stable physical and chemical stability. The physical stability is mainly reflected in high and low temperature resistance, insulation, antimagnetic, and wear resistance. In terms of chemical stability, the main surface is corrosion resistance and oxidation resistance. However, because it is a hard and brittle material, its mechanical properties cannot currently be compared with metal materials. Of course, with the advancement of material technology and improvements in product structure, this gap is gradually narrowing.

Physical stability of ceramic screws

High and low temperature characteristics: It will not deform or expand in a high temperature environment (800 degrees Celsius), and will not reduce the connection strength. Good connection strength can still be maintained at temperatures of minus 70 degrees.

Insulation properties: Zirconia ceramic screws can maintain good insulation at room temperature. The resistivity at room temperature is 10, and when heated to a certain temperature range (above 800 degrees) in the air, it can change from an insulator to a conductor.

Antimagnetic properties: Both zirconia screws and alumina screws are antimagnetic under normal conditions.

Wear-resistant properties of ceramic screws

Its ultra-high hardness (Mohs level 9) can still maintain its original shape under continuous friction, is not consumed by wear, and does not change its shape.

Chemical stability of ceramic screws

Corrosion resistance: Zirconia ceramics do not react chemically with strong acids and alkalis. In high temperature (above 200 degrees) water vapor environment, aging will occur.

Anti-oxidation properties: Zirconia ceramics have good properties of being impermeable to gases such as oxygen and liquid metals such as steel. It is widely used in high-temperature fuel cells, gas oxygen measuring probes, and metal liquid oxygen measuring probes.

Application scope of ceramic screws:

Ceramic screws have excellent properties such as high temperature resistance, insulation, non-magnetic, corrosion resistance, environmental protection and beauty, and never rust. They are not only comparable to traditional plastic screws and metal screws, but in recent years, the performance of ceramic screws has been continuously improved, and their applications The field is also becoming wider and wider, and in some fields it is constantly replacing and replacing screws in the traditional sense!

1. Aerospace industry (insulation and anti-interference devices on electronic equipment)

2. Electronic industry (insulation, anti-interference, light weight)

3. Medical device industry (insulation, non-magnetic, environmentally friendly, anti-interference code, making medical machinery and equipment safer to use)

4. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, extending equipment service life)

5. Communication industry (insulation, non-magnetic, safety)

6. Shipbuilding industry (acid-resistant, alkali-resistant, corrosion-resistant, extended service life), etc.

Performance and application comparison of ceramic screws, metal screws, and plastic screws:

Ceramic screws: The advantages of ceramic screws are high temperature resistance, wear resistance, insulation, antimagnetic, and corrosion resistance. The mechanical properties are lower than those of metal screws.

Metal screws: The advantages of metal screws are that they have strong tensile strength and fracture toughness, poor ability to withstand high temperatures, and are not insulating. Some metal screws have a certain degree of corrosion resistance.

Plastic screws: The advantages of plastic screws are insulation, antimagnetic, and special plastic screws are corrosion-resistant. It is easier to wear and is not suitable for environments that require strong connections.

Classification of ceramic screws:

By material: zirconia ceramic screws, alumina ceramic screws, silicon nitride ceramic screws

According to the head shape: hexagonal head ceramic screws, hexagonal head ceramic screws, pan head ceramic screws, flat/countersunk head ceramic screws, etc.

According to the slot shape: cross, one-word (slotted), hexagonal, rice-shaped, plum blossom, etc.
