High quality Black silicon carbide P500

High quality Black silicon carbide P500 is a suspension-treated black SiC powder. It is of higher purity since it’s acid washing and water flow sieving process. The Black silicon carbide powder has a sharper granule than that of F grit powder. That shape make grains more easily to glue sand onto coated abrasive base such as cloth and paper and stick tight on those bases.

Introduction of High quality Black silicon carbide P500

High quality Black silicon carbide P500 is a suspension-treated black SiC powder. It is of higher purity since it’s acid washing and water flow sieving process. The Black silicon carbide powder has a sharper granule than that of F grit powder. That shape make grains more easily to glue sand onto coated abrasive base such as cloth and paper and stick tight on those bases.

FAQ:

Q: Are you a manufacturer?
A: We are manufacture. We began to produce silicon carbide material since 1999.
Q: Is the carborundum powder from you made by air flow or water flow process?
A: Our carborundum powder finer than F230 are made from water flow process after acid washing. The powder get narrow particle distribution range.
Q: What grade of silicon carbide do you have?
A: Expect metallurgical black silicon carbide, the silicon carbide from us are all of A grade quality.
Q: How will you check silicon carbide quality before delivery?
A: We will check the chemical content, and cleanness of the SiC grain and powder. And inspect the gradation and bulk density of SiC grain and powder.
Q: Do you support third part quality tests?
A: Yes, we are open to get third part 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 need to provide export license to Chinese customs. We could provide it and make custom clearance in China.
Q: Are free samples available?
A: Yes, we provide free samples within 1 kg. The customer only needs 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?
A: Our capacity is 1800-2000MT per month, annually appr. 22000 MT.
