25.4±0.5mm 1inch AlN Single Crystal 400±50μM S/P/R Grade {0001}±0.5°
JDCD02-001-002 1inch AlN single crystal 400±50μm S/P/R grade
Aluminum Nitride is a highly desirable material in specific
applications where high thermal conductivity, electrical
insulation, and/or mechanical strength is required.
The material is a good electrical insulator with excellent thermal conductivity. Its high insulating properties make it an excellent choice for a variety of applications. A wide variety of products can be made from aluminum nitride.
This is the most common use for aluminum nitride. It is an
important material in the aerospace industry. However, there are
some limitations associated with it. It is unstable at high
temperatures and in some environments.
