92% white alumina ceramic substrate

The 92% white alumina ceramic substrate is a high-performance ceramic material made mainly of alumina (AlO).

High hardness: The Rockwell hardness of the alumina ceramic substrate is HRA80-90, second only to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel. This allows it to resist external physical pressure and friction, effectively protecting internal electronic components.
Excellent wear resistance: Its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. During long-term use, it can reduce the risk of performance degradation or failure due to wear.
High thermal conductivity: Alumina ceramic substrates have a thermal conductivity of up to 27 W/(m · K), which allows them to efficiently conduct heat, which is essential for electronic devices that require efficient heat dissipation.
High insulation: It has good electrical insulation properties, which can ensure the safe operation of the circuit and avoid the occurrence of short circuits and other hazards.
Chemical stability and corrosion resistance: Alumina ceramic substrates offer excellent corrosion resistance and chemical stability, allowing them to withstand long-term use under a variety of harsh conditions without failure.
Low thermal expansion coefficient: Its thermal expansion coefficient is close to that of silicon chips, which simplifies the production process of power modules and improves the reliability of the system.
Wide application fields: Due to its excellent performance, alumina ceramic substrates are widely used in semiconductor devices, microelectromechanical systems (MEMS), high-frequency switching power supplies, solid-state relays, automotive electronics, aerospace and military electronic components.

92% white alumina ceramic substrate is a high-performance, versatile ceramic material suitable for a variety of high-temperature, high-stress, and electronic packaging applications that require efficient heat dissipation and electrical insulation.
