   Color    Ivory

   Property Units Test Value
   Density gm/cc ASTM-C20 5.72
   Flexural Strength (MOR), 20 degrees C Mpa (psa x 103) -- 860 (125)
   Compressive Strength Mpa (psa x 103) ASTM-C773 1750 (254)
   Hardness Rockwell R45N -- 77.5
   Indention Fracture Toughness MPa m -- 9.9
   Endurance Limit KPsi@10^8 cycles -- 52
   Thermal Conductivity (20 degrees C) Wm degrees K ASTM-C408 2.2
   Coefficient of Thermal Expansion (25-1000 degrees C) 1 x 10-6/degrees C ASTM-C372 10.2
   Thermal Shock Resistance (Note 1) degrees C NOTE 3 350
   Maximum Use Temperature degrees C NO-LOAD COND. 500
   Impingement (Note 2) -- -- 0.63
   Rubbing (Note 2) -- -- 0.57
   Tensile Strength Mpa (psa x 103) -- 483 (70)
Note 1: Tests are run by quenching samples from elevated temperatures and listing the temperature differential at which significant flexural loss occurs.
Note 2: Wear Resistance-Impingement tests are run using a fry fused alumina abrasive. Rubbing tests are run using a dry 240 grit fused alumina abrasive. The indices in the chart are calculated by dividing the material volume loss by the volume loss of a AD-85 alumina control. The lower the index, the better the wear resistance.

The chart above is intended to illustrate typical properties only. Engineering data is representative. Property values vary somewhat with method of manufacture, size, and shape of part. This data is not to be construed as absolute and does not constitute a warranty for which we assume legal responsibility. size, and shape of part. Close control of values of most properties can be maintained if specified.
