99 Alumina ceramic round tube / shaft sleeve
Alias: Insulation precision ceramic bushing / Ceramic lined tube custom
Description：
Alumina (Al2O3) ceramics are widely used in various industrial environments and industries due to their excellent physical, chemical, and electrical properties, especially in situations where high temperature resistance, corrosion resistance, high insulation, and high mechanical strength are required.
The main material used in the manufacture of 99 alumina ceramic round tube/ceramic shaft sleeve is 99% high-purity alumina (Al2O3), ensuring its excellent mechanical properties and wear resistance.
Products Features:
1. High temperature resistance
It can withstand up to 1600°C and maintain stable performance in high-temperature environments.
2. High hardness
Vickers hardness is higher than 1500HV0.5, and its hardness is second only to diamond.
3. Good wear resistance
Its wear resistance is equivalent to 266 times that of manganese steel, which can extend the service life of the equipment.
4. Excellent insulation properties
As an electrical insulating material, it is widely used in the field of electronics and electrical applications.
5. Lightweight
The density is only half that of steel, which can significantly reduce the load on the equipment.
6. High precision
The machined plane tolerance can be 0.002 mm, and the flatness is 0.0015 mm.
Applications:
1. Electronics industry
Alumina ceramic tube sleeves first played an important role in the electronics industry. Due to its non-conductive nature, it can be used as a protective layer for electrical wires or sensitive electronic components, preventing electrical interference and environmental factors. Additionally, it has excellent thermal shock resistance and can withstand temperature differences of up to 200℃, making it excellent in high-temperature operating environments, such as up to 1650℃.
2. Electrical industry
It acts as a cable ceramic sheath and electrical insulator, protecting the wire from mechanical damage and preventing electrical faults.
3. Mechanical and structural applications
Used in mechanical installations, such as bearing sleeves and guide components, to provide sliding and structural support.
4. Heat treatment and within the furnace application
Protective sleeves used in heat treatment equipment to prevent direct exposure of sensitive components to extreme environments.
5. Chemical industry
The chemical industry is also an important application area for alumina ceramic pipe sleeves. Here, they are often used as part of chemical reaction tubes to treat aggressive chemicals. Its compressive strength is up to 2000 MPa and flexural strength is 330 MPa, ensuring structural integrity and durability during chemical reactions. Additionally, the chemical resistance of alumina ceramics allows them to withstand corrosion from multiple chemical media, ensuring the purity and safety of the reaction.
6. Scientific research and laboratory applications
In chemical and physical experiments, as a container or pipe resistant to corrosion and high temperatures.
7. Aviation and automotive industry
Used for sensor protection, especially in environments where high temperature resistance and electrical insulation are required.
