In precision investment casting, casting sand works to make the shell. There are several types of casting sand such as Mullite, Fused Aluina, Clay, and Zircon sand. The main goal is to meet different metal pouring temperatures. Thus it will achieve ideal performance and cost-effectiveness. The thermal resistance of white fused alumina is better than that of fused silica, mullite, and clay. So it is more suitable for metal and alloy castings with higher pouring temperatures.
