Chromium Corundum

FANCHUANG Chromium Corundum is a high-performance abrasive material produced by fusing premium alumina powder with a controlled amount of chromium oxide under extreme temperatures. The resulting product exhibits a distinctive pink hue, combining exceptional hardness comparable to white alumina with superior toughness.

Engineered for precision applications, FANCHUANG Chromium Corundum delivers outstanding durability and produces a remarkably smooth finish during grinding operations. Its balanced properties make it ideal for high-precision machining, including the finishing of measuring instruments, precision machine components, threaded parts, and laboratory samples.

Beyond abrasives, FANCHUANG Chromium Corundum serves multiple industrial purposes. It is widely utilized in advanced polishing systems, precision casting molds, surface coating materials, and specialized ceramic production. Additionally, its thermal and chemical stability makes it an excellent choice for refractory linings, catalyst substrates, and high-end technical ceramics.

With consistent quality and tailored performance, FANCHUANG Chromium Corundum meets the stringent demands of modern precision manufacturing and industrial processing.

 

1. Premium Raw Material Selection

FANCHUANG employs cutting-edge screening and grading technology to meticulously handpick high-grade raw materials. Their skilled workforce ensures every batch of chromium corundum meets stringent quality standards, guaranteeing superior performance and consistency.

2. Rigorous Production Process

The manufacturing of FANCHUANG's chromium corundum follows a tightly controlled 16-step procedure:

Raw material inspection → 2. High-temperature pyrolytic smelting → 3. Controlled furnace cooling → 4. Primary crushing → 5. Precision ball milling → 6. Barmack crushing & sieving → 7. Granular sand formation → 8. Residue powder filtration → 9. Chemical refinement → 10. Water-based countercurrent classification → 11. Sedimentation purification → 12. Fine powder drying → 13. Quality verification → 14. Silo storage → 15. Pre-shipment recheck → 16. Global dispatch

3. Uncompromising Product Excellence

FANCHUANG's chromium corundum exhibits:

Exceptional crystalline structure with vivid, impurity-free coloration

Optimal particle density and enhanced fracture resistance

Narrow particle distribution with minimal magnetic content for efficient material removal

99.5%+ chemical purity, extreme hardness (Mohs 9.0+), and superior self-sharpening properties

4. Comprehensive Size Portfolio

Available in three specialized formats:

Section Sand: 0-1mm / 1-3mm / 3-5mm / 5-8mm

Granular Grit: 16# / 24# / 30# / 36# / 46# / 60# / 80#

Micro Powders: 100# / 200# / 325# / 400#

5. Versatile Industrial Applications

FANCHUANG's chromium-enhanced corundum outperforms standard white alumina in:

Woodworking abrasives (produces mirror-finish surfaces)

Non-ferrous metal grinding (copper, brass, bronze)

High-pressure blasting and precision lapping
The chromium infusion significantly improves grain toughness, reducing fracture rates by 40% compared to conventional abrasives while maintaining exceptional cutting aggressiveness.
