Product introduction of China silicon carbide manufacturer supply carborundum abrasive F16-F220
Products Descripition
Black silicon carbide abrasive powder gets a superior finishing effect on glass, marble, jade, and ceramics. It is featured by the high hardness of Mohs scale 9.2 and Vicker hardness 3000-3100kg/mm2. Black SiC abrasive powder is made from suspension treatment. It gets a uniform crystal size. So it can achieve a fine and consistent lapping surface.
Advantage Introduction

FAQ：
Q: Are you a manufacturer?
A: We are a manufacturer of both black silicon carbide and green silicon carbide materials. We began to produce silicon carbide powder since 1999.
Q: What grade of silicon carbide do you have?
A: We have several grades of silicon carbide powder including refractory grade, abrasive grade,etc.
Q: How will you check silicon carbide quality before delivery?
A: We will check the chemical composition, and cleanness of the carborundum grain and powder. And inspect the gradation, bulk density of SiC grain and powder.
Q: Do you support third-party quality inspection?
A: Yes, we are open to getting a third party quality test before delivery.
Q: Is the silicon carbide you supply reclaimed material?
A: No. We do the melting process by ourselves and don’t have reclaimed silicon carbide.
Q: What is the HS code of silicon carbide abrasive powder?
A: The HS code is 2849200000.
Q: Is there any restriction to export silicon carbide from China?
A: Yes, it needs to provide an export license to Chinese customs. We could provide it and make customs clearance in China.
Q: Are free samples available?
A: Yes, we provide free samples within 1 kg. Customers only need to bear the logistic cost.
Q: What is your annual capacity?
A: Our capacity is 1800-2000MT per month, annually appr. 22000 MT.
