Product Advantages

The Essential Material for Industrial Grinding and Surface Treatment

Al₂O₃ ≥94.5%

Mohs Hardness 9.0

FEPA Standards

Why Manufacturers Prefer Brown Fused Alumina Grit?

Optimal Cost Efficiency

While maintaining sufficient cutting power, brown fused alumina costs 20-30% less than white alumina, making it ideal for rough and semi-finish grinding of carbon steel and alloy steel.

Exceptional Toughness

Uniform crystal structure prevents premature fracturing under high grinding pressure. Field data shows 15% longer service life in resin bonded wheels compared to ordinary abrasives.

Perfect Hardness-Toughness Balance

Mohs hardness of 9.0 combined with good toughness ensures effective cutting without excessive damage to workpieces.
