Product Description:

 

Chromite-base filler Sand, also known as chromite sand, is a special sand for foundry. It is a natural spinel dominated by chromite. After crushing, grinding and sieving, it is divided into prescribed grain size, and is suitable for sand for moulding (core-making). Chromium ore sand can be divided into two grades according to chemical composition, first grade Cr2O3 (> 45%) and second grade Cr2O3 (> 35%). 

 

Feature:

 

1. Heated Volume Stability

2. High thermal conductivity

3. Strong alkali resistance

4. Solid phase sintering, non-sticking sand
