High purity alumina ceramic bushing

High-purity alumina ceramic bushing is a ceramic product made of high-purity alumina as the main raw material. Compared with ordinary alumina ceramics, it has higher purity, better performance and wider applications.

The main features of high-purity alumina ceramic bushings:

high purity:

The raw materials of high-purity alumina ceramic bushings have high purity, low impurity content, and better chemical stability and mechanical properties.

Excellent wear resistance:

High-purity alumina ceramic bushings have excellent wear resistance and can withstand high-intensity friction and wear. They are suitable for high-wear conditions that require long-term stable operation.

Strong high temperature resistance:

High-purity alumina ceramic bushings have high thermal stability and can work in high-temperature environments for a long time without being easily deformed or cracked.

Good insulation performance:

High-purity alumina ceramic bushings have good insulation properties and can be used to manufacture insulating materials and high-temperature and high-voltage resistant electronic components.

Excellent chemical stability:

High-purity alumina ceramic bushings can react stably with various chemical substances at room temperature and have excellent chemical stability.

Processing costs are higher:

Compared with ordinary alumina ceramic bushings, high-purity alumina ceramic bushings have higher processing costs and require more sophisticated processing techniques and technologies.

In short, high-purity alumina ceramic bushing is a high-performance ceramic material with excellent wear resistance, high temperature resistance and chemical stability, and has been widely used in many fields.

High purity alumina ceramic bushing application range

High-purity alumina ceramic bushings are widely used in many fields due to their excellent physical and chemical properties. The following are its main application areas:

Aerospace field: 

High-purity alumina ceramic bushings are often used to manufacture aircraft engine parts and satellite components due to their high hardness, wear resistance and corrosion resistance. These parts need to work in extreme environments, and the properties of alumina ceramics meet these requirements.

Automotive industry: 

In the automotive industry, high-purity alumina ceramic bushings are also widely used. For example, automobile brake pads, clutch plates and other components can be made of alumina ceramics to improve their wear resistance and hardness.

Medical device field: 

In the medical device field, high-purity alumina ceramic bushings are also widely used. For example, artificial joints, dental implants, etc. can be manufactured using alumina ceramics. This is because alumina ceramics not only have high wear resistance and hardness, but also have good biocompatibility.

Electronics industry: 

In the electronics industry, high-purity alumina ceramic bushings are often used to manufacture substrates for integrated circuit chips because these substrates require high insulation and high corrosion resistance. In addition, alumina ceramics can also be used to manufacture equipment such as high-temperature furnace tubes.

In addition, alumina ceramics can be used in different situations depending on their alumina content. For example, 99% alumina porcelain is commonly used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals, etc.; while 95%-96% alumina porcelain is mainly used for corrosion resistance, Wear-resistant parts, etc.
