Metallized ceramic insulator

INNOVACERA’s metallized ceramic insulators are made by ceramic combined with thick metal films through a metallization process. This combination of ceramic and metal results in insulators that can withstand harsh conditions and provide electrical isolation when needed. - Metallization Spec.: - Molybdenum/Manganese (Mo/Mn) metallization: 9-30μm - Ni plating thickness: 3-10μm - Metallized Ceramic Insulators Material Properties: 1.
