Chromite Sand
Chromite sand is used in the metal casting industry due to its high thermal conductivity, which provides a chilling effect. Chromite has a low thermal expansion, which helps eliminate expansion defects. It has a glossy black appearance and a greater resistance to metal penetration than zircon. It has a higher acid demand than other sands, so you will need to use more significant amounts of acid catalyst when using furan resin.
Chromite Sand for Metal Casting
High-Performance Sand for Precision Casting
Chromite sand is the ideal choice for metal casting applications that demand exceptional thermal stability, resistance to metal penetration, and superior surface quality. With its high refractoriness and unique properties, chromite sand enhances casting performance in steel, iron, and superalloy foundries.
Why Choose Chromite Sand?
Extreme Heat Resistance—It can withstand temperatures up to 1,900°C (3,452°F), making it perfect for high-temperature casting environments.
Prevents Metal Penetration & Burn-On – Its low wettability prevents the molten metal from sticking to the mold, reducing casting defects.
Superior Chilling Effect – Enhances heat dissipation, promoting rapid solidification and finer grain structures for improved mechanical properties.
Chemical & Slag Resistance – Highly resistant to chemical reactions, preventing expansion defects and ensuring a cleaner, more accurate cast.
Low Thermal Expansion – Maintains dimensional stability, reducing the risk of warping or distortion.
Reusable & Cost-Effective – Chromite sand can be reclaimed and reused, optimizing efficiency and lowering material costs.
Applications
- Steel & Iron Castings – Ideal for stainless steel, manganese steel, and carbon steel applications.
- Precision Castings – Used in aerospace, automotive, and industrial components.
- Core & Facing Sand – Ensures smooth surfaces and prevents casting defects.
