Product Description

 

Zircon sand AFS70 AFS90 for investment casting

 

Zircon sand is a natural sand with excellent refractory properties. The zircon sand is also be called zircon silicate(ZrSiO4). It is an ideal material in foundry, refractory industry.

 

 

 

 

Features of Zircon sand AFS70 AFS90 for investment casting:

l  High refractoriness. Melting point up to 2100-2300℃.

l  Thermal resistance and chemical stability at high temperatures.

l  Neutral PH with low acidity.

l  High cleanness and good round grain shape.

l  Good grain size and fineness consistency.

l  High ability to bind with binders include both organic and inorganic ones.

l  Very low thermal expansion coefficient.

l  High thermal conductivity.

l  Low wettability.

 

Product Advantages

 

The advantage of Zircon sand AFS70 AFS90 for investment casting:

1.    Good chemical stability and low wettability prevent sand sticking on castings. It can avoid metal penetration into the mould.

2.    Low thermal expansion coefficient make casting precise shape and prevent casting unshaped.

3.    Get better surface finish of metal/steel casting.

4.    High Recyclability.

5.    Low wettability and high chemical stability will get recycled sand easy to clean and get uniform particles.
