Alumina ceramic cylindrical plug

In the industrial field that pursues ultimate precision, reliability, and durability, alumina ceramic cylindrical plugs have become indispensable core components in industries such as precision instruments, fluid control, semiconductors, and medical devices due to their excellent physical and chemical properties.

Product Core Advantage: Why Alumina Ceramics are the Ideal Choice
Aluminum oxide ceramic cylindrical plugs are made from high-purity aluminum oxide (Al ₂ O3) raw material, and are manufactured through advanced powder metallurgy and precision machining techniques. Their performance far exceeds traditional metal or plastic materials.

1. Excellent wear resistance and hardness
   Solution: Traditional metal plugs are prone to wear and tear under frequent friction conditions, leading to decreased equipment accuracy, shortened lifespan, and the generation of pollution particles.
   Our advantage: The Rockwell hardness of alumina ceramics is as high as HRA80-90, second only to diamond. This means that it has extremely high wear resistance and can withstand long-term, high-frequency reciprocating motion, greatly extending the replacement cycle and reducing equipment maintenance downtime.
2. Excellent corrosion resistance
   Problem solving: In chemical, medical, or special fluid environments, metal components are prone to corrosion and rust, affecting product purity and equipment safety.
   Our advantage: Alumina ceramics are inert materials that can resist the corrosion of the vast majority of acids, alkalis, and other chemical solvents, ensuring long-term stable operation in harsh environments and maintaining the purity of the medium.
3. Extremely high mechanical strength and high temperature resistance
   Problem solving: Metal components in high-temperature and high-pressure environments may experience creep or softening, while plastics cannot withstand high temperatures.
   Our advantage: Our alumina ceramic cylindrical plugs have high compressive strength and can maintain their shape and performance at high temperatures of 1500 ° C, with short-term use temperatures even higher. This makes it an ideal choice for applications such as high-temperature furnaces and engines.
4. Low friction coefficient and self-lubricating properties
   Problem solving: High friction can lead to increased energy consumption, heat generation, and noise.
   Our advantages: The ceramic surface has extremely high smoothness and low friction coefficient. Under certain operating conditions, its microporous structure can adsorb media to form a lubricating film, achieving self-lubricating effect and reducing driving power, resulting in smoother and quieter operation.
5. Excellent electrical insulation
   Problem solving: In electronic and semiconductor devices, conductive metal components may cause short circuits or signal interference.
   Our advantage: Alumina ceramics are excellent electrical insulators that can maintain good insulation performance even in high temperature environments, ensuring the reliability and safety of electronic devices.
