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.
