99.7% Al2o3 Ceramic Alumina Ceramic
This 99.7% alumina ceramic from Coraynic Technology Limited is a structural ceramic with a minimum Al2O3 content of 99.7%, offering electrical insulation resistance between 1x10^14 and 1x10^15 ohm-cm, mechanical strength in the range of 300 to 630 MPa, and compressive strength of 2,000 to 4,000 MPa. The material exhibits a hardness of 15 to 19 GPa, thermal conductivity of 20 to 30 W/mK, and a density of 3.75 to 3.95 g/cm3, making it suitable for high-stress electronic and thermal applications.
The ceramic is manufactured using hot injection pressing, dry pressing, 200T isostatic pressing, or extrusion, resulting in components with high corrosion and wear resistance, good gliding properties, and a low thermal expansion coefficient close to that of silicon. Its operating temperature without mechanical load spans 1,000 to 1,500°C, and it is commonly used in DBC substrates, where pure copper is bonded to the ceramic for high thermal conductivity and electrical insulation.
Typical applications include electronic ceramic substrates, vacuum devices, spark plugs, power semiconductor modules, concentrator photovoltaic arrays, and solid-state relays. Buyers in the electronics and automotive sectors source this material for its stability under high thermal and electrical loads. Coraynic Technology Limited produces these components in Shenzhen, Guangdong, with production methods tailored to the specific use case.

Sourcing 99.7% Al2O3 Ceramic Alumina Ceramic from Coraynic Technology Limited - China Import Guide
Before ordering, verify the exact alumina purity and mechanical properties with Coraynic Technology Limited, as these directly impact performance in high-stress applications. Request third-party test reports for electrical insulation, thermal conductivity, and hardness to ensure consistency with your specifications. Confirm whether the supplier can provide custom shapes or sizes to match your design requirements.
For logistics, discuss lead times for production and shipping, as well as the preferred Incoterms (e.g., FOB Shenzhen or CIF to your port). Clarify packaging standards to prevent damage during transit, especially for fragile ceramic components. Payment terms, such as TT or LC, should be agreed upon in advance to avoid delays in order processing.
Quality checks should include dimensional inspection, surface finish verification, and non-destructive testing for internal defects. Request certificates of conformity and material test reports (MTRs) from Coraynic Technology Limited. For critical applications, consider third-party inspection before shipment to ensure the material meets your technical and performance standards.
