Molten Metal Systems


Alpha crucibles are rib formed clay - graphite crucibles which have been developed with a specific modified electrical resistivity which optimises the coupling power of the crucible and avoids the risk of overheating.


They are suitable for all furnace systems of non-ferrous metal alloys and precious metals.

Alpha Typical Metal Casting Temperature 

400°C - 1400°C (752°F - 2552°F).

Performance Characteristics

  • High refractoriness ensures perfect applications for holding furnaces where maintaining metal temperature without leading to heat loss.
  • Good resistance to chemical corrosion ensures application in the most aggressive of environments.
  • Good thermal shock resistance.
  • High mechanical strength guarantees robust usage.
  • Good oxidation resistance.


Alpha crucibles are coloured black.

Pattern Range

Alpha crucibles are available in a comprehensive range of shapes and sizes to suit most end user requirements. Custom sizes can be supplied by special request.
