Foundries use silica sand as moulding and core sand to shape molten metal. It must be refractory, have a controlled AFS grain fineness and good permeability. Shiv Mines and Minerals supplies foundry-grade silica sand for iron, steel and aluminium casting.
What foundries need from silica sand
Casting sand must withstand molten metal (refractoriness), let gases escape (permeability) and hold shape at a consistent AFS grain fineness. These matter more than absolute chemical purity.
Applications in the foundry
Our foundry sand is used for:
- Moulding sand for iron and steel casting
- Core sand for internal cavities
- Non-ferrous (aluminium) casting
