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. |
