65% Zircon sand for foundry

65% Zircon sand for the foundry is from South Africa Ore. It is characterized by a low thermal expansion coefficient, high thermal conductivity, and Chemical inertness. So it can avoid casting deformation and improve casting surface quality. The Zircon sand is suitable for precise casting technology such as investment casting (Lost wax precise casting), etc.

Features of 65% Zircon sand for foundry:

• High refractoriness. Melting point up to 2100-2300℃.
• Chemical inertness with chemical stability at high temperatures.
• Neutral PH with low acidity.
• High cleanness and a good round grain shape.
• Good grain size and fineness consistency.
• High ability to bind with binders including both organic and inorganic ones.
• Very low thermal expansion coefficient.
• High thermal conductivity is higher than other foundry sands.
• Low wettability.

The advantage of zircon sand in the foundry:

1. Good chemical stability and low wettability prevent sand from sticking on castings. It can avoid metal penetration into the mold.
2. A low thermal expansion coefficient makes casting precise shape and prevents casting unshaped.
3. Get a better surface finish of metal/steel casting.
4. High Recyclability.
5. Low wettability and high chemical stability will get recycled and easy to clean and get uniform particles.
