#16 White Fused Alumina Aggregate with High Hardness for Metal Rust Removal and Surface Roughening
#16 White Fused Alumina Aggregate with High Hardness for Metal Rust Removal and Surface Roughening
White Fused Alumina is made of high-quality alumina powder through high-temperature melting, crushing and screening. It features pure white particle, high hardness, excellent self-sharpening, low iron content, acid and alkali resistance and high temperature resistance.It is widely used in precision grinding tools, stainless steel sandblasting, mold processing and high-grade refractory materials.
#16 White Fused Alumina is a coarse large-grain abrasive with strong cutting force, high purity and low impurities. It features high hardness, great impact resistance and excellent toughness, ideal for heavy rough grinding, heavy sandblasting and thick scale removal. No workpiece contamination, perfect for heavy industrial metal processing.
