Graphite FAQ Section 3
Q: What are the maintenance requirements for Graphite components?
A: Graphite requires minimal maintenance compared to metal components. In oxidizing environments above 400°C, protective coatings may be needed to prevent oxidation. Regular cleaning with compressed air or alcohol is typically sufficient for most applications. Graphite's self-lubricating properties eliminate the need for additional lubrication in mechanical applications, reducing maintenance needs significantly.
