How strong is graphite?
Graphite is known to be one of the weaker allotropes of carbon. It is not known to possess high tensile strength and is known to easily crumble under force. Pencil leads are often made up of graphite.
What is high density graphite?
High density graphite is a very special material with high density, high strength and fine micro- structure. It can be used for variety of applications because of its ability to withstand extremely high temperatures while maintaining its strength and shape.
What is characteristics of graphite?
Characteristics. Graphite is gray to black in color, opaque with a metallic luster. It is a fairly soft crystalline form of carbon with a Mohs hardness of 1 to 2. Stable and chemically inert at normal temperatures, graphite has a very high sublimation point, in the absence of air.
What is EDM graphite?
EDM-200 is an isotropic Superfine particle graphite providing good strength, surface finish, and wear resistance. Moderately priced, EDM-200 graphite provides excellent repeat- ability from electrode to electrode and from job to job.
Why graphite is used in EDM?
Graphite is being widely used in EDM mould making because of the following key advantages: Due to low wear it is time and cost effective. Easier machining with less complex milling tools. Perfect for high quality surface finishes and provides a high metal removal rate.
What are the benefits of graphite?
- It is easy to machine.
- It is very resistant to thermal shock.
- It has a low coefficient of thermal expansion (3 times lower than copper) which guarantees stability of electrode geometry during electro discharge machining.
