Advanced Ceramic Materials (ACM) offers high-purity Aluminum Nitride (AlN) Substrates, a superior ceramic material known for its excellent thermal conductivity, high electrical insulation, and low thermal expansion. AlN substrates are widely used in the microelectronics industry due to their ability to withstand high temperatures and their superior mechanical properties. The protective aluminum oxide layer that forms on the surface enhances durability, allowing use up to 1370°C.
