Aluminum Nitride Ceramic Plate, AlN Plates

Aluminum nitride (AlN) is a highly thermally conductive dielectric insulator ceramic. It provides the same high thermal and electrical properties as beryllium oxide at a more economical cost and without toxicity issues. When it comes to providing good thermal conductivity and high electrical insulation capabilities, aluminum nitride plate is an excellent choice due to their efficacy. The thermal expansion coefficient and isolation coefficient of aluminum nitride ceramic substrates are closely related to silicon products, making them very useful in electronic applications where high temperature and heat dissipation are a concern.
