8.9 X 10-6/K Thermal Expansion Alumina Ceramic The Ultimate Solution for Temperature Applications

Product Description:

The Aluminum Oxide Ceramic product, commonly known as 95% Alumina ceramic plate, is a high-performance material widely used in various industrial applications due to its exceptional mechanical, thermal, and chemical properties. This alumina ceramic is renowned for its outstanding compressive strength, hardness, thermal stability, and durability, making it an ideal choice for components that require a combination of toughness and wear resistance.

One of the most significant attributes of this alumina ceramic substrate is its impressive compressive strength, which exceeds 3000 MPa. This high compressive strength ensures that the material can withstand substantial loads and mechanical stresses without deformation or failure, making it suitable for heavy-duty applications such as wear parts, cutting tools, and structural components in demanding environments.

The hardness of the 95% Alumina ceramic plate is rated at 9 on the Mohs scale, which places it among the hardest ceramic materials available. This exceptional hardness translates to superior wear resistance, allowing the alumina ceramic to maintain its surface integrity even under abrasive conditions. This property is particularly beneficial in industries requiring materials that resist scratching, erosion, and surface degradation, such as in the manufacturing of protective coatings, electrical insulators, and precision machining parts.

Thermal expansion is another critical property of this alumina ceramic substrate. With a thermal expansion coefficient of 8.9 x 10 ^-6 /K, the material exhibits excellent dimensional stability under varying temperature conditions. This low thermal expansion rate minimizes the risk of thermal shock and structural damage when exposed to rapid temperature changes, making it highly suitable for applications in electronics, aerospace, and automotive industries where thermal cycling is common.

The flexural strength of the Aluminum Oxide Ceramic product ranges between 200 to 400 MPa, indicating its ability to resist bending forces without breaking. This flexural strength ensures that the alumina ceramic substrate can endure mechanical stresses encountered during handling, assembly, and service life, providing reliability and longevity in structural and load-bearing applications.

Additionally, the density of the 95% Alumina ceramic plate typically falls between 3.75 and 3.9 g/cm ³ . This moderate density offers a balance between strength and weight, making it a practical material choice for components where both durability and manageable weight are essential. The relatively high density also contributes to the material’s excellent thermal conductivity and electrical insulation properties, which are critical for many technical applications.

Overall, the Aluminum Oxide Ceramic product is a versatile and robust material that combines high compressive strength, outstanding hardness, low thermal expansion, and significant flexural strength with a balanced density. These attributes make the 95% Alumina ceramic plate an indispensable material in industries such as electronics, automotive, aerospace, chemical processing, and manufacturing. Whether used as an alumina ceramic substrate in electronic devices or as wear-resistant components in mechanical systems, this material delivers exceptional performance and reliability.

In summary, the alumina ceramic’s superior mechanical properties, thermal stability, and chemical inertness position it as a leading choice for engineers and designers seeking to enhance the durability and efficiency of their products. The 95% Alumina ceramic plate represents a cutting-edge solution that meets the rigorous demands of modern industrial applications, ensuring long service life and excellent performance under challenging conditions.
