Product feature: density can reach 6.05g/cm3。
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.
ceramic ball accuracy class standard( international standard IS03290~2001）
