Material Choice

Carbide or Zirconia?

Tungsten carbide sleeves give the most abrasion resistance. We use 12% cobalt and 6% nickel binder grades depending on corrosion exposure.

HIP zirconia offers high fracture toughness, high edge retention and a low coefficient of friction, with use temperatures up to 750 degrees C. It is a strong choice for MWD sleeves and gap sub rings.

Tell us the application and we will recommend the material.
