Isostatic graphite blocks are premium-grade carbon materials produced through an advanced cold isostatic pressing (CIP) process. This method ensures uniform density and fine grain structure throughout the block, resulting in exceptional mechanical, thermal, and electrical properties. These blocks are ideal for precision industries that demand consistent performance under extreme conditions.
Key Features:
Uniform Structure: Isotropic properties due to isostatic pressing guarantee consistent strength and performance in all directions.
High Purity: Typically ≥99.9% carbon content, ensuring minimal contamination in sensitive environments.
Excellent Thermal Resistance: Stable at temperatures up to 3000°C in inert atmospheres.
Superior Machinability: Easily machined into complex shapes and fine tolerances for custom components.
Low Thermal Expansion: Reduces stress under thermal cycling, ideal for high-temperature applications.
High Strength and Hardness: Suitable for use in demanding mechanical and structural environments.
Common Applications:
EDM (Electrical Discharge Machining) electrodes
Semiconductor and solar industry tooling
Mold materials for metal casting and glass forming
High-temperature furnace components (crucibles, heating elements, heat shields)
Nuclear industry components
Aerospace and defense applications
