Introduction to Alumina Ceramics

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of Alumina Ceramics

High Hardness: Alumina ceramics have extremely high hardness, which makes it very wear-resistant and suitable for manufacturing abrasive tools and parts that require wear resistance.

Wear resistance: Due to its high hardness, alumina ceramics show excellent wear resistance and are suitable for manufacturing parts for long-term use.

Corrosion resistance: Alumina ceramics have good resistance to most acids and alkalis, making them widely used in the chemical industry.

Good electrical insulation: As an excellent electrical insulating material, alumina ceramics are widely used in electronic and electrical products.

High temperature stability: Ability to withstand extremely high temperatures without significant physical or chemical changes, which makes it an ideal choice for applications in high temperature environments.

Biocompatibility: In the medical field, certain grades of alumina ceramics are used to make medical devices such as artificial joints due to their good biocompatibility.

Specifications of Wear Resistance 99 Alumina Ceramic Tube Porcelain Insulators For

Wear Resistance 99 Alumina Ceramic Tube Porcelain Insulators are engineered for high-performance applications requiring durability and reliability. The product is made from 99% alumina ceramic, ensuring exceptional purity and structural integrity. This composition delivers superior hardness and resistance to abrasive environments, making it ideal for heavy-duty industrial use.

The material’s wear resistance stands out due to its high alumina content. It withstands prolonged friction and mechanical stress without significant surface degradation. This property makes the tubes suitable for machinery parts, cutting tools, and protective sleeves in harsh conditions.

Thermal stability is another key feature. The insulators operate effectively in temperatures up to 1600°C. They resist thermal shock, maintaining performance even under rapid temperature changes. This stability prevents cracking or warping, ensuring long-term functionality in high-heat settings.

Electrical insulation capabilities are critical. The alumina ceramic provides excellent dielectric strength, preventing current leakage in high-voltage environments. This makes the tubes reliable for use in power transmission systems, electronic components, and insulating barriers.

Mechanical strength is prioritized. The tubes exhibit high compressive and flexural strength, handling heavy loads without deformation. Their hardness rating on the Mohs scale exceeds 9, rivaling materials like tungsten carbide. This toughness ensures minimal wear over time, reducing replacement frequency.

Dimensions are customizable. Standard outer diameters range from 5mm to 150mm, with lengths up to 500mm. Wall thickness varies based on application needs, balancing strength and weight. Precision machining guarantees tight tolerances for consistent performance.

Applications span multiple industries. These insulators are used in industrial machinery, semiconductor manufacturing, chemical processing, and aerospace systems. They serve as thermocouple sheaths, furnace linings, and protective housings in corrosive or high-wear environments. Customization options include surface polishing, threaded ends, and specific dimensional adjustments.

The product undergoes rigorous quality testing. Each batch is inspected for density, porosity, and dimensional accuracy. This ensures compliance with international standards for ceramic components. Packaging is designed to prevent damage during shipping, with protective padding and secure stacking.

Material sourcing emphasizes sustainability. High-purity raw materials are selected to minimize environmental impact. Production processes prioritize energy efficiency, aligning with modern industrial sustainability goals.
