Graphite for metal processing
From carbon addition to mould coatings and sintered parts, graphite serves different roles in metal processing. The right material starts with the process, the metal and the required carbon balance.
Carbon addition
Adjust carbon input for the intended metal composition.
Release & lubrication
Support separation at mould and tooling interfaces.
Powder processing
Consider graphite distribution in metal powder blends.
Where graphite is used
Identify the process first, then review the role of graphite and the requirements that guide selection.
Metallurgy
ROLE OF GRAPHITECarbon addition to iron and steel melts.
SELECTION FOCUSCarbon content · impurities · dissolution
Foundry & casting
ROLE OF GRAPHITEGraphite in mould and core coating formulations.
SELECTION FOCUSParticle size · coating system · surface finish
Powder Metallurgy
ROLE OF GRAPHITEGraphite addition to pressed and sintered metal powders.
SELECTION FOCUSPurity · particle distribution · blend uniformity
Powder Metallurgy
A dedicated selection route for sintered components.
Graphite can supply carbon during sintering and provide lubrication during compaction. Its particle characteristics need to suit the metal powder and the required part properties.
Start with the right graphite
Discuss the material family together with your specification and operating conditions.
| Material family | Application starting point | What to confirm |
|---|---|---|
| Graphite recarburizers | APPLICATION STARTING POINTCarbon addition in metal melts | WHAT TO CONFIRMCarbon, sulfur, ash and addition method |
| Natural flake graphite | APPLICATION STARTING POINTStarting material for foundry coating formulations | WHAT TO CONFIRMFlake size, purity and formulation compatibility |
| Micronized graphite | APPLICATION STARTING POINTFine graphite for metal powder blends | WHAT TO CONFIRMParticle distribution, purity and mixing requirements |
Before you select a grade
Practical questions to help make your requirements clear.
Do melting and powder metallurgy use the same graphite?
They have different selection priorities. Melt additions depend on carbon input and dissolution; powder metallurgy also requires attention to particle characteristics and distribution in the blend.
How should I specify graphite for a foundry coating?
Share the coating medium, application method, metal and surface requirements, together with the target particle distribution and purity.
What information helps with a powder metallurgy inquiry?
Include the metal powder system, desired carbon level, graphite size requirements and sintering conditions. A current specification or reference sample is useful.
