Premium Black Silicon Carbide (SiC) for High-Performance Grinding & Refractories

In modern manufacturing, the efficiency of your grinding wheels or the lifespan of your refractory linings depends on one critical factor: the quality of your raw materials. Black Silicon Carbide (SiC), with its extreme hardness and sharp crystal structure, remains the premier choice for processing materials with low tensile strength. At Yumo Abrasive, we provide high-purity Black Silicon Carbide (min. 98% SiC) tailored to the rigorous standards of global industrial leaders.

Technical Specifications & Grades

Understanding the chemical and physical properties is essential for selecting the right grit. Our Black SiC is characterized by high thermal conductivity and low thermal expansion.

Core Applications: From Grinding to Metallurgy

1. Bonded & Coated Abrasives

Yumo’s Black SiC is specifically crushed to maintain high friability. This ensures that as the grains wear down, they fracture to reveal new, sharp edges.

Best for: Cast iron, non-ferrous metals (brass/aluminum), and non-metallic materials like marble, glass, and ceramics.
Standards: Available in FEPA (F8 - F1200) and JIS (8# - 3000#) sizes.

2. High-Performance Refractories

With a high oxidation resistance and superior thermal shock stability, our SiC is a staple in the production of:

Kiln Furniture: Support plates, saggers, and muffles.
Metallurgical Deoxidizers: Improving the purity of molten steel in electric arc furnaces.

Why Choose Yumo Abrasive?

As a professional manufacturer based in Henan, China, we understand that consistency is your top priority.

Precision Screening: We use advanced airflow screening and water washing processes to ensure a narrow particle size distribution (PSD).
Customized Solutions: Whether you need Macro-grits for heavy-duty grinding or Micro-powders for precision polishing, we customize the grit shape to your needs.
Reliable Logistics: We offer 25kg or 1MT jumbo bag packaging with moisture-proof linings, ensuring the material arrives in perfect condition.

Note on Samples: We provide small samples for laboratory testing and quality verification. Please note that shipping costs are to be covered by the customer.

Frequently Asked Questions (FAQ)

Q: What is the main difference between Black and Green SiC?

A: Black SiC has slightly lower purity (98%) but higher fracture toughness, making it better for cast iron and stone. Green SiC (99%+) is harder and more brittle, used for tungsten carbide and semiconductor slicing.

Q: Does Yumo support RMB settlement for international orders?

A: Currently, we specialize in international B2B trade and do not support RMB settlement for overseas transactions. We primarily accept USD and other major international currencies via T/T or L/C.

Q: Which standards do your abrasive grains follow?

A: We strictly adhere to FEPA, JIS, and ANSI standards. Each batch comes with a detailed COA (Certificate of Analysis).
