Precision Casting Refractory Raw Material
Lowest price Chamotte sand powder Mullite 200mesh Used for
Precision Casting Refractory Raw Material, produced through high temperature calcined process, is a kind of
high quality casting sand made from the of high quality Kaolin
mines. The main crystalline phase is mullite . It has good
performance on lower thermal expansion rate, uniform expansion ,
better anti vibration, good hardness etc. It is very good to be
used for precision casting.Characteristics:
1. High refractoriness.
2. Aluminum content high, the iron content low.
3. High volume density.
4. Thermal expansion coefficients of small.
5. Physicochemical stability.
6. Fully calcined
7. Dust content low
8. The specification standards.
Advantages:
1. Easy out of shell.
2. No deformation.
3. No reduced scale.
4. Good brightness , Good finish .
5. Product rate is high.
