Aluminium nitride powder for sintering “TOYALNITE®”

TOYALNITE®

Outline

TOYALNITE is aluminium nitride powder that have high thermal-conductivity with insulating.
Toyo Aluminium has long history of producing Al powder.We developed the technology to produce AlN powder using Al powder as raw material.
We have variety grades to respond your needs.

Features

High thermal-conductivity High purity makes high thermal-conductivity after sintering.
High vending-strength High strength of sintered body is gained by broad particle size distribution.
Insulation/Thermal expansion High insulation-properties. Coefficient of thermal-expansion close to Si-chip.
