Product Description

One End Closed Glazed Alumina Metallized Ceramic Tube

Our facility supply numerous precision metallized Ceramic Tubes in aluminum oxide ceramics, aluminum nitride, zirconia and beryllium oxide for the electronical, electronic, medical, and aerospace industries. A metallic layer is applied on the specific section of ceramic base body through screen printing, pad printing and brush methods. Our capabilities allow us to metallized on flat, cylindrical, and complex ceramic bodies. Moly-Manganese (Mo/Mn) is the typical base coat materials used for metallization. Besides, we offer tungsten(W) as metallization layer.

In common case, a metal coating will be covered following by metallization layer, like nickel, gold plating. It will increase the wettability in the brazing process and prevent the Metallized Ceramics into oxidizing as well.

There many different geometry ceramic tube with metallization, like one end closed, both ends open, ceramic tube with side holes, rectangular shape tube and so on.
