As a specialized supplier of abrasives and technical solutions, Alfa Chemistry offers a high-performance brown fused alumina (BFA) sandblasting abrasive HG-AB007 that is manufactured using premium-grade brown fused alumina blocks characterized by low glass phase content, large crystal size, high toughness, and outstanding wear resistance. Through a carefully controlled crushing, screening, and reshaping process, the abrasive is engineered to deliver high purity, chemical stability, and exceptional resistance to breakage, making it particularly well-suited for applications that require high blasting efficiency, clean operation, and multiple cycles of reuse.
Key Features
- High Purity & Crystallinity: Manufactured from carefully selected raw materials in our proprietary furnaces, the BFA abrasive has minimal glassy phases and a well-developed crystalline structure, ensuring excellent cutting ability and durability.
- Superior Toughness & Wear Resistance: The large crystal size and low impurity content contribute to exceptional toughness, enabling prolonged use and resistance to fragmentation during repeated blasting cycles.
- Controlled Particle Shape: The abrasive is processed through precision crushing, screening, and reshaping steps to achieve a cubical morphology with high bulk density, optimizing energy transfer and surface finish quality.
- Chemical Stability: The inert composition ensures compatibility with a variety of substrates without risk of undesired reactions or contamination.
- Low Magnetic Content: It ensures clean blasting performance, especially in applications where ferromagnetic impurities are unacceptable.
Available Grades and Applications
- HG-AB007 abrasive: It is engineered into a cubical particle shape with a high bulk density, making it highly effective in surface preparation and finishing. It is engineered for high-performance surface preparation and is widely used in:
