Aluminum Nitride (AlN) Machining and Grinding - San

Aluminum Nitride – AlN, is most often the material of choice due to its relatively excellent thermal conductivity and non-toxic nature. AlN is somewhat more challenging than some other technical ceramic because the fine grained grinding powder adheres to the diamond tooling requiring frequent wheel dressing to allow for efficient stock removal without excessive preassure []
