Cemented Carbide Beads(NanorWC)
●Description:
NanorWC cemented carbide bead is shaped with cutting edge dropping
& rolling method from DURA and is sintered in the vacuum kiln. The
compact microstructure of bead offer the bead the highest density and
wear resistance. It is a creative invention of grinding media special
in small sizes.
●Features:
—Highest density: >14.0kg/dm3 ,
—Super hardness: >1500kg/mm2,
—Super stability: acid & alkali resistance, high temperature
resistance .
●Applications:
—For high hard material grinding: alumina, boron nitride, silicon nitride, silicon
carbide, tungsten carbide and other material.
—Nano-grinding and dispersion: higher energy transmit of small sizes of NanorWC bead guarantee
nanometer grinding in free contamination.
