White Fused Alumina WA 99.5%: Your Solution for Precision Grinding & Refractory Excellence

(Grits F12-F2000, Low Soda Advantage)

For engineers and procurement specialists demanding consistent abrasive performance, ordinary white fused alumina falls short. At Henan YUMO, we engineer WA 99.5% White Fused Alumina with ≤0.2% Na₂O across F12-F2000 grits – the industry benchmark for reliability in critical applications.

Why Low Soda (Na₂O) Defines Premium WA

Sodium oxide (Na₂O) isn’t just an impurity; it’s a silent killer of abrasive efficiency. Traditional white alumina with 0.5%+ Na₂O causes three operational nightmares:

Glass phase formation at high temperatures, weakening resin bonds by 15-30%
Moisture absorption leading to batch clumping and flow issues
Reduced crystal integrity accelerating wheel wear

YUMO’s WA 99.5% solves this through:

Triple-layer arc furnace refining to expel sodium compounds
Acid-washed surfaces eliminating free sodium ions
XRF-verified batches at ≤0.2% Na₂O (ISO 12677 certified)

Result: German automotive client extended grinding wheel life from 120 to 158 hours, cutting consumable costs by 22%.

Engineered Grits for Every Stage: F12 to F2000

From heavy material removal to micron-level finishing, our WA adapts:

Coarse Grits (F12-F80): Rapid stock removal in refractory precast shaping
Mid Grits (F100-F400): Precision grinding of alloy components
Fine Grits (F500-F2000): Mirror polishing of optical glass and semiconductors

Unlike suppliers offering limited ranges, YUMO provides full-spectrum consistency:

Particle size distribution span <0.8 (vs. industry 1.2)
98% α-Al₂O₃ crystalline structure ensuring uniform hardness
Silane-treated options for enhanced resin/polymer bonding

Applications Where Low-Sodium WA Excels

Refractory Manufacturing
≤0.2% Na₂O prevents kiln lining cracks caused by sodium volatility at 1600°C+.
High-Precision Grinding Wheels
Low-soda WA extends wheel lifespan and maintains cutting sharpness.
Semiconductor Polishing
F2000 micro-powder with controlled Na+ ions avoids wafer contamination.
Metal Surface Finishing
Consistent grit geometry delivers scratch-free surfaces on stainless steel/copper.

The YUMO Advantage: Beyond Specifications

REACH & EU Compliance: Full documentation for hassle-free EU imports
Custom Grading: Laser sizing to your exact F-number requirements
Global Logistics: 30-day delivery to EU/US with Hamburg warehouse stock
Technical Support: Application engineers optimize grit-to-bond ratios

Case Evidence: Low Sodium = Lower Costs

A Polish abrasives manufacturer switched to YUMO’s WA 99.5% (F220 grit):

Grinding wheel failure rate ↓ 37%
Annual abrasive waste savings: €41,200
Production downtime eliminated

“The ≤0.2% Na₂O guarantee gave us batch consistency we’d never seen before.”
– Marek Kowalski, Production Director
