Tungsten Carbide Beads（DURA-WC）
●Description:
DURA-WC tungsten 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
crushing strength and wear resistance. It is a creative invention
of grinding media specially in with small sizes.
●Specialty:
—Highest density: >14.0kg/dm3 ,
—Super hardness: >1500kg/mm2,
—Higher crushing Strength: >250kgf ,
—Super stability: acid & alkali resistance, high temperature
resistance.
●Application：
—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 DURA-WC bead guarantee nanometer grinding.
