RFQ Checklist
- Target grain size (e.g., 5-15 microns)
- Ash content / purity limits
- Operating temperature and atmosphere
- Critical tolerances, surface finish, and fragile features
- Certificate requirement, destination, and end use
Ultra-fine grain graphite with uniform properties in all directions, ideal for high-precision and demanding applications.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Grain Size | 5 - 15 microns | Finer grain provides smoother surface finishes and better edge retention in CNC and EDM processes. |
| Bulk Density | 1.75 - 1.90 g/cm³ | Higher density reduces porosity and increases mechanical strength and oxidation resistance. |
| Purity / ash requirement | Commercial, purified, or buyer-specified limit | Purity requirements can change material availability, certificate scope, cleaning, and export review. |
They refer to different particle sizes and densities. IS-15 typically implies a finer grain and higher strength suitable for detailed EDM work.
Large, simple furnace or metallurgical parts may be more economical in molded or extruded graphite if fine detail and isotropic properties are not required.
Purification planning depends on grade, geometry, final dimensions, and certificate requirements. It should be discussed before production release.
