棕刚玉F砂通用粒度号为F*-F**0,粒度可按国标及各国标准生产，其化学成分视粒度大小而不同。突出特点是晶体尺寸小耐冲击，颗粒多为球状颗粒，具有纯度高，质地致密，堆积密度大，自锐性强，韧性好，磁性物含量低的特点。适用于制造陶瓷磨具、树脂磨具和研磨、抛光等。除国标以外，还可按照ISO. ANSI. FEPA、JIS等标准或是客户的具体要求生产。

      The universal particle sizes range is F4~F**0. Particle sizes could be produced according to GBand dfferent countries' standards. Its chemical composition changes depending on its particle sizes.Its prominent characteristic is small crystal size and impact resistance. Most of particles are spherical. Italso has other characterstics like high purity, dense texture, high bulk density, strong self-sharpening,good toughness, low content of magnetic material. It is appliled to produce vtrified wheels, resin bondedabrasives, and also used for grinding, polishing, etc. Except GB Standard, we could produce BrownFused Aumina according to IsO, ANSI, FEPA, JIS and customers' specific requrements.
