BFA Abrasive (P-grit)

Inquire Now

As a specialized supplier of abrasives and technical services, Alfa Chemistry provides high-quality, high-performance materials for industrial surface treatment and finishing. Among our flagship products is brown fused alumina (BFA) P-grit, a synthetic corundum abrasive engineered for superior performance in coated abrasive applications. By leveraging in-house smelting technology and stringent quality control, we offer a product that meets the exacting demands of modern grinding and polishing industries.

Key Features

Our BFA abrasive is produced using proprietary electric arc furnaces, allowing full control over the smelting process. This results in a material with:

Low Crystal Agglomeration: It ensures uniform particle distribution and better abrasive performance.
Large Crystal Size: It enhances toughness and grinding stability.
Low Vitreous (glassy) Content: It minimizes brittleness and improves mechanical integrity.
High Toughness and Wear Resistance: It supports prolonged service life under demanding conditions.
Excellent Chemical Stability: Compatible with various bonding agents in coated abrasive production.

Available Grades and Applications

We offer specific grades of BFA P-Grit, each meticulously designed to optimize performance for distinct applications:

HG-AB005 Abrasive

Characteristics: This grade features a sharp, angular morphology and low bulk density. Its inherent strong self-sharpening ability ensures that new, keen edges are continuously exposed during use, maintaining high grinding efficiency.
Coated Abrasive Performance: Coated abrasives produced with HG-AB005 are renowned for their exceptional sharpness, superior heat dissipation, and high grinding efficiency. These attributes are crucial for preventing workpiece damage and extending abrasive life during high-speed or aggressive grinding.
Primary Applications:
General coated abrasive production.
Manual grinding of various metals.
Hand sanding and finishing of wood.

HG-AB006 Abrasive

Characteristics: HG-AB006 is characterized by its polyhedral shape and moderate bulk density. This multi-faceted structure provides numerous cutting edges, offering a balanced approach to abrasive performance.
Coated Abrasive Performance: Abrasive tools manufactured with HG-AB006 deliver an excellent blend of good sharpness, enhanced durability, and high grinding efficiency. This versatility makes it suitable for a broader range of demanding applications.
Primary Applications:
Manufacturing of sanding cloth, sandpaper, and sanding belts.
Processing low carbon steel and alloy steel.
Grinding and finishing hard wood materials.
