Description
Definition of Water-Based Graphite
Water-based graphite, or aqueous graphite emulsion, is an industrial lubricant composed of extremely fine graphite particles suspended in water along with binders and anti-corrosion additives.
This material is a safer, cleaner, and lower-smoke alternative to oil-based or solvent-based lubricants and is widely used in die casting, gravity casting, forging, and hot extrusion industries.
Structure and Composition of Water-Based Graphite
| Component | Role |
|---|---|
| Natural or synthetic graphite (1–20%) | Solid lubrication, heat resistance up to 800–1000 °C |
| Distilled or industrial water (70–90%) | Base solvent and cooling agent |
| Binder and emulsifier | Suspension stability and adhesion to metal |
| Anti-rust / anti-foam additives | Increased die life and spray stability |
Applications of Water-Based Graphite in Industries
-
In Aluminum and Cast Iron Casting
-
Coating ladles, crucibles, and pouring spoons
-
Protective layer on metal molds to prevent sticking of molten metal
-
Helps achieve uniform mold filling
-
Lubrication of runners and gating systems
-
In Forging
-
Spray on hot dies before each stroke
-
Prevents hot steel from sticking to the die
-
Facilitates workpiece removal from the die
-
Increases die life and reduces wear
