Product Details

alumina ceramic high quality ceramic insulation substrate

Alumina substrate is widely used in LED ceramic suite, Printers, direct bonding copper and HIC.

The advantages of alumina ceramic substrates :

The main material of our products is high purity quality alumina, which cause no negative effective effect to the grinded material.

High density and hardness, impact resistance, low loss rate, smooth surface and no contamination to product.

With high grinding efficiency which can reduce grinding time to reduce energy cost and being good for environment protection.

Alumina ceramic substrate application

Working in high temperature enviroment.

Abrasive application etc.
