Metallized ceramic cone

Meetcera supplies precision metallized ceramic components in aluminum oxide ceramics for the military, medical, and aerospace industries. Through spray, needle, and brush coatings or screen printing our capabilities allow us to metallized on flat, cylindrical, and complex ceramic bodies. Moly-Manganese is the typical base coat materials used for metallization.
