Alumina ceramic substrates are the most widely used ceramic substrate materials in the precision electronics and semiconductor industries. With excellent electrical insulation, stable chemical properties, and reliable thermal conductivity, alumina substrates deliver dependable performance in high-temperature and high-frequency environments.

Key Properties:

• Purity grades: 96% / 99% / 99.6% available

• Excellent electrical insulation (high volume resistivity)

• Good thermal conductivity (~20–35 W/m·K)

• High temperature, corrosion & wear resistance
