Application: zirconia balls (ZBB) are mainly used as valve balls,fully ceramic bearings, force measurement balls,trackballs, fine mill balls, and can be used in such situations: high temperature, anti-corrosion, electric insulation, anti-magnet, non-lubrication, it’s the ideal material for replacing steel balls under corrosive situation.
Product standard: 0.4mm~50.8mm(1/64"~2"), can provide other different kinds.
Provide grade:G3~G60
Notes:
1 The color is white, if necessary, we can provide yellow ones.
2 We have mass stock, can deliver anytime you want.
3 Can meet the requirements of various non-standard sizes
4 Coefficient of thermal expansion of zirconic is 10.5×106/℃, close to the coefficient of thermal expansion of metal, match up with metal but dimensional changes a lot under different temperature, so in some critical situations it’s not as stable as silicon nitride.
