Характеристики

Metallized ceramics：

Metallized ceramics is coated with

a metal film (molybdenum, manganese, tungsten, silver, etc.) on the surface of ceramics, which is sintered in a metallized high-temperature furnace to achieve a firm combination of ceramics and metals. At present, the company has thick film method, film method, activation method and other processes, can achieve 95%-99.7% alumina ceramics, aluminum nitride ceramics, beryllium ceramics, sapphire, diamond and other surface metallization.
