Sic Ceramic Ball The density of Sic Ceramic Ball is 3.2g/cm3 and it’s the same as
Si3N4 ball, at 1400℃, the intension and rigidity almost couldn’t be
changed. Sic Ceramic Ball has the self-lubrication that can solve
the pollution of lubricate medium. Comparing with Si3N4, Sic
Ceramic Ball has higher rigidity, lower anti-press strength and
lower rupture toughness. Staple Material and Manufacturing Presision | | Ceramic Balls | Plastic balls | Glass Balls | Stainless Balls | meterial | Zr02,Si3N4,SiC,Al2O3 | POM,PE,PP,PA,UPE,PEEK | GLASS | 440C,304,316,316L | grad | G5-G200 | G100-G1000 | G100-G1000 | G10-G200 |
