South Africa Chrome ore AFS60-65 Iron casting sand
Product Introduction of South Africa Chrome ore AFS60-65 Iron casting sand
South Africa Chrome ore AFS60-65 Iron casting sand is a natural spinel mineral sand. The main chemical in chrome ore sand is Chromium oxide and ferrous. 46% purity chrome ore sand is especially suitable for metal & steel & iron casting sand. It works well as core sand, molding sand, chill sand, and facing sand in foundry applications. Chrome ore sand featured high refractory, low expansion rate, and low thermal conductivity. It helps avoid sand sticking and makes better casting shapes.

FAQ:
Q: Where are you located?
A: Our factory is located in a tariff-free Zone at Lianyungang port. So it will be convenient to export.
Q: What is your main market?
A: Our main market is local China and Asia-Pacific regions.
Q: What is the difference between your chromite sand and Original South Africa Chromite sand?
A: In our factory, we take production processes on original South Africa such as washing, magnetic removing, and sieving. So it is cleaner with fewer impurities, and less magnetic content. The cleanness of chromite from us is just proper for the foundry industry. In the meantime, we will get a precise AFS size and make customized particle size distribution to the requirement.
Q: What is the MOQ?
A: No. We don’t have a limit on MOQ, but for a small quantity, the transportation cost would be high.
Q: Can you provide free samples?
A: Yes, free samples within 25 kgs are available. You only have to bear the express cost.
Q: What is the delivery time for one container?
A: What is your capacity each year?
Q: Our capacity per year is 2500-3000 tons.
A: Generally the lead time of FCL is 7-10 days. A bigger quantity will get a longer delivery time.
Q: What is the HS code of Chromite sand?
A: The chromite sand HS code is 2610000000.
Q: Do you get MSDS of chromite sand?
A: Yes. You can download it from our website or get it from our sales team.
