Product Description:

Al2O3 Ceramic, commonly known as Aluminum Oxide Ceramic or Alumina Oxide Ceramics, is a highly versatile and widely used advanced ceramic material renowned for its exceptional mechanical and electrical properties. This ceramic material is engineered to meet the demanding requirements of various industrial applications, ranging from electrical insulation to wear-resistant components. The unique combination of its attributes makes Al2O3 Ceramic an ideal choice for applications requiring high strength, excellent dielectric properties, and outstanding hardness.

One of the most notable features of Al2O3 Ceramic is its remarkable dielectric strength, rated at 14 KV/mm. This high dielectric strength ensures that Alumina Oxide Ceramics provide excellent electrical insulation, making them suitable for use in high-voltage applications and electronic devices where reliable insulation is critical. The excellent dielectric properties contribute to the material’s ability to withstand high electric fields without breaking down, which enhances the safety and longevity of electrical equipment.

In addition to its superior dielectric strength, Aluminum Oxide Ceramic exhibits an impressive breakdown voltage of 20 KV/mm. This characteristic further underscores the material’s capacity to endure extreme electrical stresses, preventing electrical discharge and failure in insulating components. The high breakdown voltage makes Al2O3 Ceramic a preferred material for insulators, substrates, and other components in power electronics and telecommunications industries.

Mechanical strength is another critical advantage of Alumina Oxide Ceramics. With a compressive strength of 3000 MPa, Al2O3 Ceramic can withstand significant mechanical loads and pressures without deformation or failure. This high compressive strength enables the material to be used in structural applications and components exposed to heavy mechanical stresses. Whether in aerospace, automotive, or industrial machinery, Aluminum Oxide Ceramic parts maintain their integrity under challenging conditions.

Hardness is a defining characteristic of Alumina Oxide Ceramics, with a rating of 9 on the Mohs scale. This exceptional hardness makes Al2O3 Ceramic highly resistant to wear, abrasion, and scratching, which is essential for components subjected to harsh operating environments. The hardness of Aluminum Oxide Ceramic allows it to serve effectively in applications such as cutting tools, wear-resistant coatings, and protective liners, where durability and longevity are paramount.

Furthermore, the dielectric constant of Al2O3 Ceramic is measured at 9.6, indicating its excellent ability to store electrical energy in an electric field. This property is particularly valuable in capacitor substrates and other electronic components where energy storage and dielectric stability are crucial. The moderate dielectric constant of Alumina Oxide Ceramics balances insulation with energy storage, optimizing performance in electronic circuits.

Al2O3 Ceramic is also chemically stable, corrosion-resistant, and biocompatible, broadening its application scope to include medical devices and chemical processing equipment. Its resistance to high temperatures and chemical attack ensures reliable performance in extreme environments, contributing to reduced maintenance costs and longer service life.

In summary, Al2O3 Ceramic, or Aluminum Oxide Ceramic, offers a superior blend of electrical insulation, mechanical strength, hardness, and dielectric properties. Its dielectric strength of 14 KV/mm, compressive strength of 3000 MPa, breakdown voltage of 20 KV/mm, hardness of 9 Mohs, and dielectric constant of 9.6 make it a premium choice for a wide range of industrial, electronic, and structural applications. Whether used in high-performance electrical insulators, wear-resistant parts, or advanced electronic components, Alumina Oxide Ceramics deliver reliable, durable, and efficient performance that meets the highest standards of modern engineering and technology.
