Brown fused aluminum oxide 220# for cleaning of turbine parts
220# Brown Fused Aluminum Oxide (BFA) is a high-performance abrasive specially engineered for precision blast cleaning of turbine parts, fully compliant with industrial precision surface treatment requirements for power generation equipment such as gas and steam turbines.
Crafted from high-purity bauxite via electric fusion and precise grading, this abrasive features a sharp angular particle shape, uniform 220# grit size, and Mohs hardness of ≥9—delivering strong cutting power and consistent blasting effect. It effectively removes rust, scale, oil stains and surface contaminants from turbine components without causing excessive wear or surface damage, ensuring the precision and integrity of turbine metal substrates and mating surfaces.
With low impurity content (free silica ≤1.0%), low moisture (≤0.2%) and strict control of water-soluble chlorides (≤25ppm), it avoids secondary contamination of turbine precision parts and meets the high cleanliness standards of power plant equipment maintenance. Packaged in sealed 20kg plastic pails, it ensures storage stability and easy on-site operation.
Ideal for blast cleaning of turbine blades, rotors, casings and other core components, our 220# BFA balances cleaning efficiency and surface protection, making it a reliable choice for power generation industry turbine maintenance and overhaul.
