Large Size Isostatic Graphite Blocks for Industrial Structural Components
Product Description
Large Size Isostatic Graphite Blocks are designed for industrial applications requiring oversized components with consistent properties and high structural reliability. Utilizing advanced isostatic pressing technology, these graphite blocks maintain uniform density and isotropic performance throughout their entire volume, even at large dimensions.
The material exhibits excellent mechanical strength, low thermal expansion, and strong resistance to thermal shock. These properties make it suitable for large structural components exposed to high temperatures and mechanical loads. The homogeneous microstructure ensures predictable behavior during machining and service.
Large Size Isostatic Graphite Blocks are widely used in metallurgical furnaces, crystal growth equipment, continuous casting systems, and large heat treatment installations. They can be machined into beams, plates, frames, and other custom structural components according to specific industrial requirements.
Despite their size, these graphite blocks offer good machinability, enabling precise shaping and tight tolerances. Their long service life and stable performance help reduce downtime and maintenance costs in large-scale industrial operations.
Key advantages include design flexibility, structural stability, and cost-effective performance for heavy-duty industrial applications requiring large graphite components.
| Comparison Parameters | Advantages |
|---|---|
| Production costs | Graphite of the same volume costs only about 25% that of copper electrodes. |
| Machining Speed | The machining speed is 3–5 times faster than copper electrode, the machined surface is smooth. The electric discharge machining speed is 1/3 to 2 times faster than that of traditional copper electrodes, making it more suitable for rough machining. |
| Machining accuracy | Good machining precision, C.T.E is 1/4 of copper, easy polishing. |
| Weight | The density of graphite is only 1/5 of copper, it's more suitable in the production for larger electrode. |
| Loss | Used as EDM electrode, which consumption is only 1/3–1/5 of copper electrode, the coating of spark decomposition of carbide compensates electrode loss. |
| High temperature resistance | The melting point of graphite is up to 3650℃, with no deformation under high-temperature working conditions, and more suitable for machining bone electrode. |
| Electrode Cohesiveness | Damaged graphite parts can be bonded with conductive adhesive, effectively saving production time and reducing material costs. |
