Ceramic Casting Sand

Ceramic Casting Sand is a commonly used foundry material. A foundry practices method produces castings of high precise dimensions, smooth surface, free of blowholes and casting defects. Ceramic casting sand offers outstanding core performance and is recommended for castings having thin section cores and intricate designs. It requires a lower addition of binder and withstands high temperature (Softening point beyond 1800 degree Celsius), and has a low thermal expansion coefficient. This makes it a perfect core base material.

$350.00 – $450.00 / MT
