DFP-1C

Particle Size   Hardness
microns 5 SSH 65
µ·inches 200    
Coefficient of Thermal Expansion Electrical Resistivity
microns/m °C 8.5 µ·ohm·cm 270
µ·in/in °F 4.7 µ·ohm·in 120
Compressive Strength Apparent Density
N/mm2 210 g/cc 3.12
psi 30,500 lb/in3 0.1120
Flexural Strength Thermal Conductivity
N/mm2 117 watts/m K 175
psi 17,000 BTU·ft/hr·ft2·°F 100
Tensile Strength (1) Oxidation Threshold (2)
N/mm2 65 °C 500
psi 9,500 °F 930

(1) Estimated at 70% of flexural strength.
(2) Temperature that results in 1% weight loss in 24 hours. Oxidation threshold increases by approximately 100� C if graphite is purified.
