Description
Excellent Corrosion Resistant White Black Electrical Ceramic Disc
Electrical ceramic disc technical data:
- Surface roughness:Ra0.1
- Tolerance:+-0.001mm
- Process: Sintering,Grinding, CNC Machining
- Cylindricity: 0.004mm
- Parallelism:0.002mm

Features of Electrical ceramic disc:
1.Excellent mechanical strength
2.Excellent wear resistance
3.High impact resistance
Application: In the field of structural ceramics, zirconia ceramics are widely used due to their advantages such as high toughness, high flexural strength, high wear resistance, excellent thermal insulation performance, and a thermal expansion coefficient close to that of steel. The main applications include Y-TZP grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro fan shafts, optical fiber pins, optical fiber sleeves, drawing dies and cutting tools, wear-resistant cutting tools, clothing buttons, watch cases and straps, bracelets and pendants, ball bearings, lightweight golf club heads, and other room-temperature wear-resistant components.
