Black silicon carbide 55C F220

Black silicon carbide 55C F220 is produced by a premium reshape milling process. Then the material is washed with acid and fully cleaned with water. So there is much less dust in the grits. In the meantime, it gets a higher bulk density. That type of black silicon carbide grit is suitable for making abrasive wheels.

FAQ:

Q: Are you a manufacturer?

A: Our company is a manufacturer. We began to produce silicon carbide material in 1999.

 

Q: What grade of silicon carbide do you have?

A: Expect metallurgical black silicon carbide, the silicon carbide from us is all of A-grade quality.

 

Q: How will you check silicon carbide quality before delivery?

A: We will check the chemical content, cleanness of the SiC grain and powder. And inspect the gradation, bulk density of SiC grain and powder.

 

Q: Do you support a third-party quality test?

A: Yes, we are open to getting the third-party quality test before delivery.

Q: Are the silicon carbide material from you is reclaimed material?

A: No. We only produce A-grade silicon carbide produced from high-quality melted SiC blocks.

 

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 the lead time for each order?

A: It depends on the quantity required. Generally 5-10 days for FCL(20-25MT).

 

Q: What is your annual capacity?
