Premium Calcined BFA, Blue-Fired BFA, and Ceramic-Coated Alumina for enhanced cutting performance and bonding strength.
Description: Regular BFA grains treated at a temperature of approximately 1050°C.
Key Characteristics: This process heals micro-cracks within the grains, significantly increasing toughness and reducing magnetic substance content. It offers better hydrophilicity (bonding strength with resins).
Applications: High-end vitrified wheels, heavy-duty grinding wheels, and high-quality coated abrasives.
Description: Treated at a much higher temperature (around 1350°C), giving the grains a distinct blue-brown color.
Key Characteristics: Exceptional toughness and chemical stability. The high-temperature treatment ensures maximum density and hardness, making it superior for aggressive cutting.
Applications: Premium coated abrasives (sandbelts), high-speed cutting discs, and processing of hard metals like alloy steel.
Description: Regular BFA grains coated with a layer of inorganic ceramic material on the surface.
Key Characteristics: The coating increases the surface roughness and the specific surface area, which dramatically improves the bonding strength between the grain and the resin binder.
Applications: High-performance resin-bonded cutting wheels and flap discs to prevent premature grain shedding.
Description: A top-tier product that combines both "Blue Fired" heat treatment and "Ceramic Coating" technology.
Key Characteristics: It possesses the extreme toughness of blue-fired grains and the superior adhesion of ceramic coating. It offers the longest service life and the highest efficiency in the BFA family.
Applications: Professional-grade sandbelts and cutting tools for stainless steel, high-carbon steel, and heat-resistant alloys.
Product Overview: A premium abrasive material developed through advanced high-temperature calcination and specialized coating processes, applying a layer of metal salts and ceramic materials to the surface of WFA.
Key Features:
- Enhanced Toughness: High-temperature treatment significantly boosts toughness and compressive strength while maintaining sharpness.
- Superior Adhesion: Ceramic coating increases surface roughness for much stronger bonding.
- High Purity & Durability: Tools made with this material are sharper, have a longer service life, and demonstrate higher efficiency.
Applications: High-performance cutting discs, grinding wheels, coated abrasives (sandpaper/sandbelts), and refractory materials (investment casting, refractory bricks).
