Thermal Conductivity 25 to 35 W per mK Alumina Ceramic Material Designed for Electrical Insulation and Thermal Management

Product Description:

Aluminum Oxide Ceramic, commonly known as alumina ceramic, is a highly versatile and widely used advanced ceramic material renowned for its excellent mechanical, electrical, and thermal properties. This product is primarily composed of aluminum oxide (Al2O3), which gives it outstanding durability and performance characteristics, making it an ideal choice for various industrial applications. The alumina ceramic substrate offers exceptional strength and reliability, ensuring long-lasting functionality in demanding environments.

One of the most notable attributes of this aluminum oxide ceramic is its remarkable compressive strength, which exceeds 3000 MPa. This high compressive strength makes the alumina ceramic substrate highly resistant to mechanical stress and deformation, allowing it to withstand heavy loads and harsh conditions without compromising its structural integrity. As a result, it is widely used in applications that require superior wear resistance and mechanical robustness.

In addition to its mechanical strength, aluminum oxide ceramic exhibits excellent electrical properties, particularly its high dielectric strength, ranging from 18 to 20 KV/mm. This attribute makes the alumina ceramic substrate an excellent electrical insulator, capable of preventing electrical breakdown even under high voltage conditions. Its outstanding dielectric strength is essential for use in electronic components, insulators, and substrates where reliable electrical insulation is critical.

The density of this alumina ceramic ranges between 3.75 and 3.9 g/cm³, which contributes to its robust and stable nature. The relatively high density indicates a compact microstructure with minimal porosity, enhancing its mechanical and thermal properties. This density range ensures that the alumina ceramic substrate maintains its dimensional stability and thermal conductivity, which are vital for applications involving heat dissipation and thermal management.

Another significant property of aluminum oxide ceramic is its exceptional insulation resistance, which is greater than 10¹² Ohm-cm. This ultra-high insulation resistance makes the alumina ceramic substrate an outstanding material for applications requiring electrical isolation and minimal leakage currents. It ensures that electrical components remain safe and efficient, even in environments exposed to moisture, dust, and other contaminants.

Alumina ceramic is also known for its excellent chemical stability and resistance to corrosion and abrasion. The aluminum oxide ceramic surface is inert to most chemicals and does not easily degrade when exposed to harsh chemicals, acids, or alkalis. This makes the alumina ceramic substrate suitable for use in chemical processing equipment, medical devices, and other applications where chemical resistance is crucial.

Moreover, aluminum oxide ceramic exhibits excellent thermal stability and can operate effectively at high temperatures without significant loss of strength or electrical properties. The alumina ceramic substrate is commonly used in high-temperature environments, including furnace components, heat exchangers, and thermal insulation parts, where both mechanical strength and electrical insulation must be maintained under extreme thermal conditions.

Thanks to its combination of high compressive strength, superior dielectric properties, high density, and exceptional insulation resistance, aluminum oxide ceramic continues to be a preferred choice for manufacturers and engineers seeking reliable and high-performance ceramic materials. The alumina ceramic substrate is integral in producing electronic substrates, insulators, cutting tools, wear parts, and other industrial components.

In summary, aluminum oxide ceramic is a premium material that offers a unique blend of mechanical strength, electrical insulation, chemical stability, and thermal resistance. Its compressive strength of over 3000 MPa, dielectric strength between 18 and 20 KV/mm, density ranging from 3.75 to 3.9 g/cm³, and insulation resistance exceeding 10¹² Ohm-cm make the alumina ceramic substrate an exceptional choice for a wide range of applications. Whether used in electronics, mechanical engineering, or chemical processing, alumina ceramic delivers outstanding performance and reliability.
