IJ Research offers a non-magnetic and electrically conductive ceramic since 1998. We are proud to provide this electrically conductive ceramic for applications where a metal or alloy may not be preferred. The electrical conductivity is approximately that of Fe or Ni. While  Fe and Ni are magnetic, IJ Research ceramic #1129 is not. One of the production applications we have experience with is an electrode where wear resistance, hardness and high current density are the critical parameters. Our customer has stated that #1129 works better than WC for the specific application. Other common applications include electrodes and sensors for harsh chemical, including HCl and/or HF environments.

We are able to supply the bulk ceramic machined/ground to a final shape (plate, rod, pin etc.) with very tight tolerances. We are also able to PVD sputter to provide a durable, conductive coating.
