95% Alumina Metallized ceramic furnaces for Automobile industry/innovacera

1. Introduction:

Our Ceramic metallization Technologies produces industrial products with exceptionally strong bond strengths. Our thick film metallization inks utilize a Moly-Manganese (MoMn) refractory formula that is designed for oxide ceramic substrates. Metallizing materials include a variety of precious metals.


We understands metallizing, brazing, and metal-to-ceramic joining. Whether you are adding an electronic circuit path to one of our high-purity substrates or joining a metal component with ceramic, our metallization, brazing and joining experts help you select the most effective and cost-efficient method and material.
