CALCAST® is a high performance technical ceramic board manufactured from Calcium Silicate.

The non-wetting properties of CALCAST® are ideally suited for use in direct contact with non-ferrous molten metal applications. The higher density grade exhibits extremely low shrinkage – ideal for use in applications which require the product to retain its dimensional integrity.

Densities range from 850kg/m3 through to 1050kg/m3 with operating temperatures from 850˚C to 1000˚C. CALCAST® is machined to bespoke shapes in our fully automated CNC shop.

CALCAST® is typically used for applications such as launder sections, troughs, dams, skim-dams, sprue bushes, intermediate tubes, nozzles, down-spouts, plugging sticks, hot-top rings and transition rings. CALCAST® is also ideally suited as a hot-face lining for holding furnaces and as an insulator in various heat treatment equipment.

Other benefits include:

  • Non wetting to molten aluminium
  • High strength
  • Excellent insulation properties
  • Energy efficient
  • Long lasting
  • Machinable
  • Hot Face Lining for direct contact with Molten Aluminum in Dosing/Holding Furnaces
  • Launders/Troughs
  • Oven and Dryer Shelving
  • Aluminium Consumables such as Floats, Spouts and Transition Plates
  • Back-up Insulation for Kilns and Furnaces
Typical Composition
