Superhard Materials: Unlocking Extreme Performance with Henan Yumo New Materials

At Henan Yumo New Materials Co., Ltd., we specialize in the research, production, and supply of world-class superhard materials. Our products are engineered to meet the exacting standards of global clients and deliver consistent performance under the most demanding applications.

What Are Superhard Materials?

Superhard materials are substances with exceptional hardness, usually ranked at the top of the Mohs scale (8–10). These materials can cut, grind, polish, and wear down even the toughest metals, ceramics, and stones. Their superior hardness makes them ideal for abrasives, cutting tools, blasting media, and refractory applications.

At Yumo, we focus on synthetic superhard materials with controlled crystal structure, high purity, and customizable grain size.

Our Core Superhard Products

1. White Fused Alumina (WFA)

• Chemical Composition: High-purity α-Al₂O₃ (aluminum oxide)

• Hardness: Mohs 9

• Color: Pure white

• Features: Sharp edges, high friability, strong cutting ability

• Applications: Precision grinding of high-carbon steel, stainless steel, ceramic polishing, sandblasting, refractory linings

WFA is ideal for applications requiring low iron content and clean surface finish. Its high refractoriness and hardness make it perfect for advanced industrial use.

2. Brown Fused Alumina (BFA)

• Chemical Composition: Al₂O₃ with traces of TiO₂ and Fe₂O₃

• Hardness: Mohs 9

• Color: Brown

• Features: High toughness, strong impact resistance, excellent durability

• Applications: Grinding wheels, resin-bonded abrasives, refractory bricks, sandpaper, heavy-duty blasting

BFA is an economical, durable abrasive widely used in metal surface preparation and refractory manufacturing.

3. Green Silicon Carbide (GSiC)

• Chemical Composition: >99% SiC

• Hardness: Mohs 9.5

• Color: Green

• Features: Extremely sharp, high thermal conductivity, excellent corrosion resistance

• Applications: Grinding hard alloys, glass, ceramics, solar silicon, semiconductors

GSiC is the preferred choice in precision lapping and fine polishing due to its sharp grains and thermal behavior.

4. Black Silicon Carbide (BSiC)

• Chemical Composition: SiC with slight free carbon

• Hardness: Mohs 9.2–9.4

• Color: Black

• Features: High strength, good thermal conductivity, lower cost than green SiC

• Applications: Sandblasting, refractory coatings, ceramic foams, grinding cast iron and non-ferrous metals

BSiC is a versatile, cost-effective superhard abrasive with a wide range of industrial applications.
