# Foundry crucibles

Graphite crucibles for containing and melting metals in foundry and laboratory use.

Family: Metallurgical applications

## Description
Graphite crucibles for containing and melting metals in foundry and laboratory use.

Grade selection depends on the metal or alloy, operating temperature, atmosphere and how aggressively the crucible is cycled. The wrong grade shortens life through thermal shock, erosion or contamination risk.

ESGRAF supplies commercial shapes when stocked and custom crucibles machined from drawing. Share metal, temperature, geometry and quantity for a technical recommendation.

## Processes
- Melting
- Holding liquid metal
- Pouring

## Challenges
- Thermal shock
- Erosion
- Metal contamination
- Short life of unsuitable crucibles

## Advantages
- Excellent thermal shock resistance
- High thermal conductivity
- Stock and custom options

## Limitations
- Wear from erosion and thermal shock
- Possible metal contamination if the grade is unsuitable
- Service life depends on cycles and metal flow
