Which of the following is NOT a characteristic of graphite as an EDM electrode material?

Graphite is widely used as an electrode material in Electrical Discharge Machining (EDM) due to several advantageous properties. One significant characteristic of graphite is its ability to conduct electricity, making it effective for transferring electrical signals during the machining process. Additionally, graphite is known for being easily machined. It can be shaped and formed into intricate designs without excessive effort, facilitating the creation of fine features in EDM operations.

Its performance at high temperatures is another strong point; graphite maintains its structural integrity under heat, making it well-suited for the demands of the EDM process where thermal conditions can be extreme.

In contrast, the statement regarding low wear resistance does not apply to graphite in the EDM context. Graphite typically exhibits adequate wear resistance, especially when compared to other materials under similar conditions. This resistance helps ensure that the electrode maintains its shape and functionality over multiple machining cycles, thereby affirming the effectiveness of graphite as an EDM electrode material.
