Al2O3 Alumina Ceramic Valves Disc for Brass Cartridge
ceramic valve:
1,90%-95% Alumina Ceramic valve.
2.High intension.
3.Solid-resist,alkali-resistence.
4,Reasonable price.
Specification of the tap ceramic disc:
- OD: 12.5mm---16.2mm ceramic discs
- The frictional times is 300, 000 to 500, 000
- Rigidity is 84~86 HRA.
- The thickness tolerance is less than 0.05mm, the diameter tolerance is less than 0.05mm.     Â
