Monocrystalline fused alumina is an electro-fused abrasive produced by fusing high purity alumina with special alloys. Each particle is a single crystal, resulting in more sharp, strong edges that contribute to better bonding and sharper cutting action when molded into a bonded abrasive.
By eliminating sulfur from the production process, this environmentally friendly monocrystalline alumina is the future for cool-cutting alumina abrasives.
Monocrystalline fused alumin's high hardness and unique microstructure create numerous
and durable cutting edges, which lead to dramatically improved performance when compared to white fused alumina or even chrome-doped alumina. Its unique micro crystals of fine fragmentation, laminated together, forming a well-developed single crystal, with good toughness, good self-sharpening, large grinding ratio, high grinding rate.
