Metalized ceramic bushings are widely used in ceramic to metal joining processes. The reasons for using metalized ceramic bushings are the insulation properties of the ceramic material, the brazing strength of the ceramic to metal bond, and the hermeticity of the bond. Along with standard bushings, Du-Co can offer many custom shapes and sizes. The current standard steatite bushing sizes can be seen in the illustration to the right.
