Notes:

* All properties measured at room temperatures except for C.T.E (R.T to 1000°C) and measured with grain, if not stated otherwise. Flexural strength determined using third point loading.

* C.T.E=Coefficient of thermal expansion

* These properties are typicial average value and not guaranteed

* 1MPa=10.2kgf/cm²

* 1W/mK=0.86kcal/m-h-°C
