Custom Alumina ceramic parts are custom-designed and manufactured to meet specific application requirements, with customized shapes, sizes, and properties. Below is a detailed introduction:

Performance

High Hardness and Wear Resistance: Alumina ceramic has a Mohs hardness of 9, second only to diamond, and its wear resistance is approximately 20 times that of stainless steel, allowing for long-term use in high-wear environments.

High Temperature Resistance: Alumina ceramic can operate in atmospheric environments up to 1750°C and maintain 50% of its room-temperature tensile strength even at temperatures of 1000°C.

Corrosion Resistance: Alumina ceramic is highly resistant to most chemical corrosives, including acids, alkalis, and organic solvents, surpassing most metals in corrosion resistance.

Electrical Insulation: Alumina ceramic has high resistivity and excellent electrical insulation properties, maintaining good insulation even in high-temperature environments.

Low Friction: A smooth surface with a low friction coefficient reduces drag and wear during material conveying. 

Customization Range

Shape and Size: We can customize various shapes, such as ceramic substrates, ceramic rods, Ceramic Tubes, Ceramic rings, and ceramic gaskets. These sizes range from tiny electronic components to large components exceeding 1000mm in diameter and 3000mm in length.

Purity Options: Alumina with varying purities can be selected based on specific application requirements, such as 95%, 99%, 99.5%, 99.7%, and 99.9%.

Performance Requirements: We can adjust the formulation and production process to meet diverse performance requirements, such as improving thermal conductivity, increasing toughness, and optimizing electrical insulation.

Production Process

Raw Material Preparation: We select high-purity alumina powder and, if necessary, add small amounts of additives to improve the ceramic's properties.

Molding Process: We select the appropriate molding process based on the shape and size of the custom part, such as dry pressing, isostatic pressing, injection molding, and slip casting. Sintering: The formed green body is sintered in a high-temperature furnace, typically at temperatures between 1600°C and 1800°C, to achieve a dense ceramic structure.

Precision Machining: Sintered ceramic parts require precision machining, such as cutting, grinding, and polishing, to meet dimensional accuracy and surface quality requirements.

Application Areas

Electronic Engineering: Customized alumina ceramic insulation sleeves, ceramic windows, vacuum chucks, and other products are used for insulation, protection, and support of electronic components.

Mechanical Industry: Customized alumina ceramic guide rails and arms are used in high-end processing equipment and automated production lines to improve precision and wear resistance.

Chemical and Energy: Customized alumina ceramic nozzles, ceramic plates/sheets, and ceramic balls are resistant to corrosive liquids and gases and are used for chemical material conveying and equipment linings.

New Energy Vehicles: Ceramic bearings and alumina ceramic components are used in motor spindles and other applications, offering advantages such as insulation, high-temperature resistance, and lightweight construction. Medical field: Customizable alumina ceramic crowns, artificial joints, etc. are widely used in the medical field due to their good biocompatibility and long wear life.
