Black carborundum abrasive grain F54
Product introduction of Black carborundum abrasive grain F54
Black carborundum abrasive grain F54 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.
