JC3 is a dense fine-grained rod that is machinable and rated to a high temperature of 5432F | 3000C. It?s properties allow for good electrical conductivity and is typically used for electrochemical applications. If you are operating 1355F | 735C please review our JC4 Graphite Rods. Temperature Rating: 5432? | 3000? Grade: Extruded Graphite JC3 Apparent Density: 1.72-1.74 g/cc Benefits Machinability to exceptionally close tolerances. Good Thermal Conductivity as graphite is an excellent heat conductor and has great resistance to thermal shock. High Compressive Strength ranging from 11K-38K lbs/in² Corrosion Resistance for all practical purposes and is unaffected by most acids, alkalis, solvents, and similar chemicals. Seal face flatness due to the high modulus of elasticity and stability to remain flat during operation at the rubbing faces. Built-in Lubrications and Non-Galling. Products will not seize or gall in the most severe applications as the molecular structure of graphite forms an extremely thin film on moving parts. Porosity. Graphite can be porous but impregnants are used to fill these pores and can range from high to totally impervious depending on need. Check out our GraphiSeal. Applications Heat Treating applications. Used to support hearth rails or beams to allow for thermal expansion. Fixtures or support post. Electrodes, stir sticks, and other reaction purposes.
