Machinable Aluminum Oxide and Alumina Ceramics

With its properties of electrical insulation and excellent thermal conductivity, Aluminum Nitride Ceramics is ideal for applications where heat dissipation is required. In addition, since it offers a coefficient of thermal expansion (CTE) near that of silicon, and excellent plasma resistance, it is... [See More]
