Product Description

High purity metallized alumina ceramic Washers

Metallized ceramic washer is commonly made out of high purity aluminum oxide ceramics which covered a metal plating on the certain section as per customers' requirement.

We provide a selection of metallization types,mainly including as below:

1. Ceramic base body + Mo/Mn metallization ..............................................2. Ceramic base body + Mo/Mn metallization + Nickle(Ni) plating

3. Ceramic base body + Silver(Ag) plating.................................................................4. Ceramic base body + Tungsten(W) metallization + Gold(Au) plating

We offer a wide of metallized ceramics, like metallized ceramic tube, metallized ceramic substrate, metallized ceramic ring, metallized ceramic disc and a variety of metallized ceramic insulator in high vacuum technology. We support prototyping to high volume production, whatever a very small trial batch, or a very large mass production. We are able to achieve it smoothly.
