Hardness 9 Mohs Alumina Ceramic Aluminum Oxide Ceramic Offering Excellent Thermal Conductivity and Mechanical Durability

Product Description:

Aluminum Oxide Ceramic, commonly known as Alumina ceramic, is a highly versatile and widely used engineering ceramic renowned for its exceptional mechanical, electrical, and thermal properties. This material is predominantly composed of 99% Alumina ceramic, which ensures superior purity and performance in various industrial applications. Alumina ceramic plates made from this material offer outstanding durability, high wear resistance, and excellent stability under extreme conditions, making them a preferred choice for demanding environments.

One of the most significant characteristics of Aluminum Oxide Ceramic is its impressive Young's Modulus, ranging between 200 to 400 GPa. This high modulus of elasticity indicates the material's exceptional stiffness and resistance to deformation under stress, which is essential for components subjected to mechanical loads. The stiffness of Alumina ceramic ensures that parts retain their shape and functionality over prolonged use, even in high-pressure settings.

In addition to mechanical strength, Alumina ceramic exhibits excellent dielectric properties, making it ideal for electrical insulation applications. With a dielectric strength of 18 to 20 KV/mm, Alumina ceramic plates provide robust resistance to electrical breakdown, allowing them to withstand high voltages without failure. This high dielectric strength is critical in electronic components and systems where reliable insulation is paramount to safety and performance.

Alumina ceramic also boasts a Poisson's Ratio of approximately 0.25, which reflects its ability to maintain dimensional stability when subjected to mechanical forces. This property ensures that the material undergoes minimal lateral expansion or contraction when compressed or stretched, contributing to its structural integrity in complex assemblies and devices.

When it comes to tensile strength, Aluminum Oxide Ceramic is remarkably strong, with values ranging from 200 to 400 MPa. This tensile strength allows Alumina ceramic plates to endure significant pulling or stretching forces without fracturing, making them suitable for use in structural components and wear-resistant surfaces. The balance of high tensile strength and toughness makes Alumina ceramic an excellent material for applications requiring both rigidity and resilience.

Another critical electrical property of Aluminum Oxide Ceramic is its breakdown voltage, which exceeds 20 KV. This high breakdown voltage underscores the material's ability to resist electrical failure even under intense electrical stress. Consequently, Alumina ceramic is extensively used in high-voltage insulators, substrates for electronic circuits, and other electrical insulating components where safety and reliability are crucial.

Overall, 99% Alumina ceramic plates and components fabricated from Aluminum Oxide Ceramic offer a combination of high mechanical strength, excellent electrical insulation, and outstanding thermal stability. These attributes make Alumina ceramic indispensable in industries such as electronics, aerospace, automotive, and manufacturing. Whether used as protective covers, electrical insulators, or wear-resistant parts, Alumina ceramic reliably delivers performance that meets the rigorous demands of modern technology and industrial processes.

In summary, Aluminum Oxide Ceramic stands out as a premium material characterized by its Young's Modulus of 200-400 GPa, dielectric strength of 18-20 KV/mm, Poisson's Ratio of 0.25, tensile strength of 200-400 MPa, and breakdown voltage exceeding 20 KV. The use of 99% Alumina ceramic ensures high purity and consistent quality in every Alumina ceramic plate, making it a top choice for engineers and designers seeking a durable, high-performance ceramic material.
