30-60 Mesh High-aluminum Mullite Refractory Sands for Mold Making of Investment Casting with Low Thermal expansion
1. Production Introduction and Application
The mullite refractory sand has high aluminum content, low iron content, small dust, reasonable particle size distribution, high bulk density, high temperature strength and low residual strength.
Available:10~16 mesh,16~30 mesh,30~60 mesh,60M,70 mesh,100 mesh,200 mesh,325 mesh.other sizes can be customized.
Mainly used in the aluminum smelting industry, refractory materials, precision casting , aluminum silicate refractory fiber and ceramic industry.
We have different grades of refractory sands for you to choose.
30-60mesh Grade I
30-60Mesh Grade II
30-60MESH Grade III
