If I was buying 실리콘 카바이드 abrasives in the United States, 나는 가장 큰 회사를 찾는 것부터 시작하지 않을 것이다.
I would start with a much simpler question, which is:
The supplier makes refractory materials from silicon carbide.
That difference is important.
High-temperature furnaces are used by some companies to produce silicon carbide crude. Others purchase crude material and process it into controlled abrasive grains, macrogrits, microgrits and fine powders. Some focus on water classification, blending, magnetic separation or precision powder processing.
All these capabilities may matter to an industrial buyer.
This guide covers 7 silicon carbide manufacturers in U.S. based processors that supply silicon carbide grains and powders for applications including grinding, 랩핑, 폭파, 접착 연마재, 코팅된 연마재, 도예, refractories and polishing.

1. Washington Mills
If my priority were finding a true U.S. silicon carbide producer, Washington Mills would be the first company I would evaluate.
The company manufactures its CARBOREX® line of silicon carbide grains and powders and states that it produces silicon carbide crude as well as processing that material into customized grains and powders.
Its product range includes:
- 검은 실리콘 카바이드
- 녹색 실리콘 카바이드
- Macrogrits
- 마이크로그리트
- 미세분말
- Specialty high-purity SiC

Washington Mills also describes a production process in which the quality and chemistry of the crude SiC affect the properties of the finished grains and powders.
For buyers looking for SiC for bonded abrasives, 코팅된 연마재, 폭파, 도예, 내화 벽돌, or industrial processing, I consider Washington Mills one of the most relevant companies on this list.
다음에 가장 적합: Buyers prioritizing domestic primary SiC production and broad particle-size capabilities.
2. Electro Abrasives LLC
Electro Abrasives is based in Buffalo, New York and specializes in silicon carbide abrasive processing.
Its current company profile describes the business as a North American producer of water-classified black and green silicon carbide powders and microgrits. It also produces macrogrits and coarse mesh sizes for applications including bonded and coated abrasives, 세련, 내화 벽돌, 산업용 연마재, technical ceramics, and wire sawing.
This is an important capability because producing a good microgrit is not simply a matter of crushing SiC into smaller pieces.
Fine abrasive powders require controlled classification so that oversized and undersized particles remain within the required distribution.

I would consider Electro Abrasives particularly relevant for customers purchasing:
- Fine black SiC
- Fine green SiC
- 마이크로그리트
- Lapping powders
- 정밀 연마재
다음에 가장 적합: Buyers requiring tightly controlled fine SiC powders and microgrits.
3. K.C. Abrasive Company
K.C. Abrasive Company is located in Kansas City, Kansas and describes itself as a specialty abrasive powder manufacturer.
Its product range includes both black and green silicon carbide powders. The company positions SiC as an abrasive for cutting, 랩핑, 연마, and finishing materials such as glass, quartz, porcelain, 대리석, carbide, 주철, 구리, and brass.
What interests me about K.C. Abrasive is its focus.
Rather than being a huge diversified industrial group, the company concentrates heavily on abrasive powders and finishing materials.
That can be useful when the purchasing requirement is relatively specific.

I would consider K.C. Abrasive for:
- 랩핑
- 연마
- 세련
- 유리 가공
- Ceramic finishing
- Industrial abrasive formulations
다음에 가장 적합: Buyers looking for an established U.S. abrasive powder specialist.
4. Micro Abrasives Corporation
Micro Abrasives in Westfield, Massachusetts is more focused on precision abrasive powders.
Its MICROGRIT SIC series is produced using precision water classification. The company states that the resulting SiC powders are graded for applications including bonded and coated abrasives, wire sawing, 도예, 내화 벽돌, precision lapping, 연마, 그리고 폴리싱.
나를 위한, this company becomes more interesting as particle size gets smaller.

A buyer producing a conventional grinding wheel may have very different requirements from a company doing precision lapping or fine polishing.
Micro Abrasives is therefore worth considering when particle-size consistency is more important than simply obtaining low-cost bulk grit.
다음에 가장 적합: 정밀 랩핑, 세련, 마이크로그리트, and fine abrasive powder applications.
5. Advanced Abrasives Corporation
Advanced Abrasives Corporation is located in Pennsauken, New Jersey.
Its silicon carbide range includes black silicon carbide powder with abrasive sizes from approximately F80/100 through F1200, as well as silicon carbide lapping and polishing compounds.
The company states that it uses grading and classification processes to control particle-size distribution and grain characteristics.

Applications listed for its black SiC include:
- 랩핑
- 세련
- 접착 연마재
- 코팅된 연마재
- 압력 폭파
- 연마
- 세라믹 가공
- Glass finishing
Advanced Abrasives is especially relevant when the application requires more than simply purchasing standard bulk grit.
예를 들어, its Premasol silicon carbide compounds are available in multiple micron ranges and different carrier systems for precision finishing.
다음에 가장 적합: Precision finishing, controlled SiC powders, and lapping/polishing formulations.
6. AGSCO Corporation
AGSCO operates processing facilities in Libertyville, Illinois and Pine Brook, New Jersey.
The company supplies silicon carbide for applications including lapping, 절단, and industrial flooring, but the main reason I include it is its U.S. mineral-processing capability.
AGSCO provides services including:
- Screening
- Blending
- Mixing
- Coating
- 포장
- Private labeling
Its ISO 9001-certified processing facilities are equipped with screeners, mixers, blenders, and packaging systems.

I would therefore describe AGSCO as a U.S. silicon carbide processor and supplier, rather than a primary SiC furnace producer.
For many buyers, however, that distinction does not reduce its usefulness.
If I need a particular size distribution, blended product, custom package, or private-label abrasive material, downstream processing capability can be more important than owning the furnace that originally produced the crude SiC.
다음에 가장 적합: Custom sizing, blending, 포장, and industrial mineral processing.
7. U.S. Electrofused Minerals
U.S. Electrofused Minerals, or USEM, operates from Aliquippa, Pennsylvania and is part of the Curimbaba Group.
USEM states that it both distributes products from affiliated companies and manufactures industrial mineral grains and powders in the United States. Its product portfolio includes black silicon carbide, 녹색 실리콘 카바이드, and metallurgical silicon carbide.

Its SiC products serve markets including:
- 접착 연마재
- 코팅된 연마재
- 랩핑
- 세련
- 폭파
- 내화 벽돌
- Advanced ceramics
- 야금 응용
The company also supplies products according to grading systems including ANSI, 밥을 먹이다, ISO, 그, and customer-specific standards.
Its green SiC offering includes material for grinding wheels, honing stones, 폭파, compounds, 랩핑, 그리고 폴리싱, while its black SiC is available for both industrial and coated abrasive applications.
다음에 가장 적합: Buyers wanting a broad range of abrasive-grade SiC grains and powders from a U.S.-based industrial mineral company.
What If I’m Open to Silicon Carbide Suppliers Outside the USA?
U.S.-based suppliers can be a good choice when local inventory, shorter domestic lead times, and easier communication are the main priorities. 하지만, I would not limit my sourcing options to the United States if I were purchasing silicon carbide in larger volumes or needed more flexibility in grit size, 포장, or pricing.
China is one of the major sourcing markets I would consider for 검은색 실리콘 카바이드, 녹색 실리콘 카바이드, 실리콘 카바이드 그릿, and fine SiC powders. For buyers using silicon carbide in abrasives, 연마, 폭파, 세련, 내화 벽돌, 도예, or other industrial applications, sourcing directly from an experienced Chinese manufacturer can provide more options for customized specifications and bulk supply.
One supplier I would include in my comparison is 허난 유모 신소재 유한회사, 주식회사., a China-based manufacturer and supplier of industrial abrasive materials.
Its main product range includes:
- 블랙 실리콘 카바이드
- 녹색 실리콘 카바이드
- Silicon Carbide Grains
- Silicon Carbide Fine Powders
- 흰색 융합 알루미나
- 브라운 용융 알루미나
- Other industrial abrasive materials
What makes Henan Yu Mo particularly relevant to abrasive buyers is its focus on abrasive grains and powders rather than semiconductor-grade silicon carbide.
최종 생각
Choosing the best silicon carbide manufacturers in USA will depend on your application, desired grit size, 청정, processing needs and budget. U.S. suppliers can be good options for local availability and domestic processing, while overseas manufacturers may be more flexible for bulk orders and customized specs.
If I compare both options I would also add Henan Yu Mo New Material Co., 주식회사. in China Especially for black silicon carbide green silicon carbide SiC grains and fine powders. I would look at a combination of factors – sample, 입자 크기 분포, Certificates of Analysis, lead times and total delivered cost – instead of just the price before making a final choice.
