Applications of Foundry Silica Sand
Metal Casting Industry
Our washed silica sand is widely used for manufacturing molds and cores for casting various ferrous and non-ferrous metals.
- Steel Foundries
- Cast Iron
- Ductile Iron
- Aluminum Casting
- Copper Alloys
- Brass Components
- Bronze Parts
Sand Casting Applications
Fine silica particles improve mold strength and provide excellent dimensional accuracy. Green sand molds composed of silica sand, clay, and water remain the most common casting method worldwide. Dry sand molds are also produced for higher mechanical strength and better surface finish.
- Excellent mold stability
- Reduced hot tearing
- Smooth casting surfaces
- High permeability
- Superior dimensional precision
Refractory Applications
Due to its outstanding heat resistance, silica sand is widely used as a refractory material in induction furnaces and high-temperature industrial equipment.
- Steel furnaces
- Iron melting furnaces
- Ceramic kilns
- Glass furnaces
- Cement plants
- Industrial refractory linings
