Hengtium's 36-grit brown fused alumina is manufactured with the specific requirements of cutting discs in mind-from the selection of raw materials to the smelting process.
We use high-quality bauxite as the raw material and employ an extended smelting process lasting approximately six hours. Our large-scale furnaces and transformers ensure stable smelting conditions, allowing the brown fused alumina crystals to fully develop.
The grains subsequently undergo a shaping process to optimize their morphology for the production of resin-bonded cutting discs. This ensures greater control during manufacturing and results in cutting discs that deliver fast, stable cutting performance.
Advantages of 36-Grit Brown Fused Alumina

Extended Smelting Time for Superior Crystal Development
The differences found in standard brown fused alumina often stem from the smelting process.
Hengtium employs a smelting cycle of approximately six hours, utilizing large furnaces and high-capacity transformers to ensure raw materials melt thoroughly under stable, high-temperature conditions.
Enhanced crystal formation yields abrasive grains that balance strength and toughness-a critical factor for resin-bonded cutting discs.
The grains must neither shatter upon initial contact nor remain dull without shedding.

High Toughness for Continuous Cutting Operations
If the abrasive is too brittle, it tends to fracture prematurely during operation;
Conversely, if the grains become overly dull, cutting efficiency suffers.
This 36-grit product emphasizes crystal quality and grain toughness, enabling the abrasive to withstand impact while maintaining consistent cutting action.
It is ideal for cutting discs used on steel, carbon steel, stainless steel, and other metal materials.

High Bulk Density for Optimized Volumetric Abrasive Utilization
High bulk density is another key feature of this 36-grit brown fused alumina designed for cutting discs. Shaping the grains optimizes the space between them, allowing for a higher volume of abrasive material to be packed into a given space.
This enables precise control over the abrasive-to-resin ratio and the structural integrity of the finished product.
