Alumina/Al2O3 Ceramic Components
Coraynic Technology Limited manufactures alumina (Al2O3) ceramic components in grades A-95, A-97, A-99 and A-99.8, tailored for applications requiring high mechanical strength, insulation and corrosion resistance. The components are formed using cold isostatic pressing, hot die casting or dry compression, achieving micrometre-level precision and size ranges from inner diameters as small as 0.2 mm to outer diameters up to 300 mm. Metallization capabilities enable ceramic-to-metal sealing for electric vacuum, aerospace and nuclear power applications.
Alumina ceramics are chosen for their hardness, wear resistance and electrical insulation, with higher purity grades (e.g., A-99.8) offering superior dielectric strength and thermal conductivity. The company’s self-developed metallization formula ensures strong bonding between ceramics and metals like oxygen-free copper or titanium alloys, enabling hermetic seals for high-pressure or vacuum environments. Cold isostatic pressing produces uniform density, while dry compression suits high-volume production of complex shapes.
Buyers of these components include manufacturers in microelectronics, optoelectronics and aerospace industries, where reliability under extreme conditions is critical. Coraynic Technology Limited’s products are used in feedthroughs, insulators and structural parts for devices operating in high-temperature or corrosive environments. Confirm the grade, metallization requirements and dimensional tolerances with the supplier to match your application’s specifications.

Sourcing Alumina/Al2O3 Ceramic Components from Coraynic Technology Limited - China Import Guide
Before sourcing alumina ceramic components from Coraynic Technology Limited, confirm the exact grade (A-95, A-97, A-99 or A-99.8) and its corresponding properties, such as dielectric strength, hardness and thermal conductivity. Request dimensional drawings and tolerance specifications for your component, and verify whether metallization or ceramic-to-metal sealing is required for your application.
Logistics for ceramic components from China often involve air or sea freight, depending on urgency and volume. Clarify Incoterms (e.g., FOB Shenzhen or DDP your facility) and payment terms (e.g., TT or LC) with the supplier. Ensure your receiving process can handle fragile components, and check for any import restrictions on advanced ceramics in your country.
Quality checks should include visual inspection for cracks or surface defects, dimensional verification using calipers or CMM (Coordinate Measuring Machine), and functional testing for electrical insulation or hermeticity if applicable. For metallized components, test the bonding strength between the ceramic and metal using methods like pull testing. Request the supplier’s quality control documentation, including material certificates and test reports.
