Density 375 to 39 grams per cubic centimeter Alumina ceramic aluminum oxide ceramic components applied in medical and electronic devices

Product Description:

The Aluminum Oxide Ceramic product, commonly known as alumina ceramic, is a highly versatile and widely used advanced ceramic material renowned for its exceptional mechanical, thermal, and electrical properties. This product is predominantly composed of aluminum oxide (Al2O3), and is available in various forms, with the alumina ceramic plate being one of the most popular configurations. Among these, the 99% alumina ceramic plate stands out due to its superior purity and performance characteristics, making it ideal for demanding industrial and technological applications.

One of the key attributes of the aluminum oxide ceramic product is its excellent thermal conductivity, which ranges between 25 to 35 W/mK. This thermal conductivity is considerably higher than many other ceramic materials, enabling efficient heat dissipation in applications where temperature control is critical. The alumina ceramic plate is therefore widely used in electronic substrates, heat sinks, and other thermal management components, where maintaining stable operating temperatures is essential for performance and longevity.

The density of this alumina ceramic product typically falls within the range of 3.75 to 3.9 g/cm³. This relatively high density contributes to the material's outstanding mechanical strength and durability. The 99% alumina ceramic plate, in particular, benefits from this density range, offering enhanced wear resistance, hardness, and structural integrity. These qualities make alumina ceramic an excellent choice for applications involving abrasive environments, such as cutting tools, wear-resistant liners, and protective components.

Another important mechanical property of aluminum oxide ceramic is its Poisson's ratio, which is approximately 0.25. This ratio indicates the material's ability to deform elastically under mechanical stress, reflecting its balanced combination of stiffness and ductility. The alumina ceramic plate exhibits good dimensional stability under load, making it suitable for precision engineering applications where maintaining shape and size under stress is critical.

In addition to its mechanical and thermal properties, aluminum oxide ceramic is also prized for its outstanding electrical insulation capabilities. The dielectric strength of this material ranges from 18 to 20 KV/mm, making alumina ceramic an excellent electrical insulator. This high dielectric strength enables the alumina ceramic plate to withstand high voltage applications without electrical breakdown, which is crucial in electronic components, insulators, and substrates used in high-frequency and high-voltage environments.

The 99% alumina ceramic plate, with its combination of high purity and superior physical properties, is particularly favored in industries such as electronics, aerospace, automotive, and chemical processing. Its resistance to corrosion, wear, and thermal shock further enhances its suitability for harsh environments, providing long service life and reliability. Whether used as a structural component, an insulating substrate, or a protective barrier, alumina ceramic delivers consistent performance and durability.

Overall, aluminum oxide ceramic products, including the alumina ceramic plate and the 99% alumina ceramic plate, represent an optimal solution for a wide range of industrial applications. Their blend of high thermal conductivity, mechanical strength, electrical insulation, and chemical stability makes them indispensable in modern manufacturing and technology sectors. When precision, reliability, and performance are paramount, alumina ceramic stands out as a material of choice, offering unmatched versatility and value.
