Chromium ore sand (Chromite sand) and chromium iron are two different materials.  There are the following differences between them:

Chromite flour 325 mesh is a natural chromite material, which is selected from natural chromite ore through screening. Compared with high-purity green chromium oxide powder, natural chromite powder has a cost advantage.Chromite flour has the following properties in terms of performance:

Chromite powder is a good chromium material in the glass bottle industry. The chromium oxide in it can work as a colorant for green color glass bottles. To meet this demand, Haixu company opened a new production line to manufacture chromite fine powder materials.

China supplier Foundry chromite ore sand is a type of sand that is primarily used in foundry applications, particularly in the production of metal castings. Here are some properties of foundry chromite sand:

The main chemical element of chromite sand AFS45-55 is chromium oxide. For the iron & steel castings, the Cr2O2 should be at least 46% and SiO2 content less than 1%.  It has high specific gravity and is one of the best high-temperature resistant materials in natural minerals. It has strong thermal conductivity and can be used in various casting processes. Meanwhile, it can eliminate the casting of sand-stick defects substantially.

Chromite sand AFS45-55 is a superior molding sand for water glass casting. The water glass process is usually suitable for the production of precision steel castings. Traditional water glass casting mainly uses silica sand as molding sand and surface sand. However, it can easily cause volume expansion or contraction of castings. It greatly affects the dimensional accuracy of castings. Replacing silica sand with Chromite sand can reduce the defect rate caused by size errors. AFS45-55 is a mostly used specification.
