Keral 99

Keral 99

Alumina content ≥ 99.6%

Keral 99 is a high alumina substrate material with a clarity of ≥99.6%. Due to the high degree of clarity and fine-grained structure, it has a very high thermal conductivity of up to 30 W/mK. The dielectric strength is the highest among KERAFOL® ceramic substrate materials.

We laser cut the material according to your wishes!

Please submit your CAD data.
