High Purity Porous Alumina Substrates(NA-99F)
NIKKO’s high-purity porous Alumina substrates offer excellent surface flatness and are lightweight, ideal for sintering tooling material.
Features
As sintering tooling material – the high-purity based Alumina substrates that provide superior surface flatness contribute to the characteristics, quality, and yield of the sintered products. They are also ideal for sintering high reactive material. With the capability of controlling the porosity during the sintering process of the substrates, various porosity levels are available.
