Our high-purity isostatic graphite is produced through high-temperature chemical purification of isostatic graphite, achieving a purity level of 6N, a compressive strength exceeding 80 MPa, and a resistivity of 8-14 μΩ·m. This material exhibits isotropic properties and consistent performance, with precision machining ensuring excellent dimensional accuracy, geometric uniformity, and surface finish, thereby maintaining long-term stability in critical heat treatment environments.
