High Precision 95% 99% 99.5% Al2O3 Aluminium Oxide Alumina Ceramic Rods
95%alumina:
1). 95% alumina or steatite ceramic.heat compression molding,the alumina has been to improved insulation and mechanical strength.
2). The ceramics have no cracks,no burrs,no pinholes,no gaps,and no impurities, surface is smooth, dye absorption is passed.
3).Linear dimension tolerance ≤ ± 0.05mm, diameter tolerance ≤ ± 0.1mm, hole size distortion ≤ 0.05mm, circumference deformation size ≤ 0.1mm.
4). Insulation Resistance ≥ 100MΩ (have been checked by megohm in DC500V).
5). Dielectric Strength: AC2000V/50HZ/1min no breakdown phenomenon.
6). Linear expansion coefficient is slight,and less than 7.0 × 10-6mm /°C, and good for thermal shock performance.
7). Sintering temperature is 1350 °C, the use of a temperature not lower than 1100 °C, good corrosion resistance.
Type of ceramic plunger shaft piston rod us manufacturer (including but not only belows)
| Shaft plunger | Pump plunger |
| Wear Plunger rod | Filling Pump plunger |
| Pins rod | Water Pump plunger |
| Pump piston rod | Plunger rod |
| Pump shaft rod | Sleeve and bushing plunger |
| Machinable plunger | Piston plunger |
Tip: For different industries, equipment,and environment, ceramic plunger have different function, We can machining ceramic plunger shaft piston rod , such as surface polishing, internal and external pipe wall threads, metal parts bonded, different shapes etc by custom requirement. | |
Dimension and tolerance:
·Diameter as small as 0.2mm, depends on length
·Length as long as 550mm, as short as 0.5mm
·Diameter tolerance we could make as fine as 0.001mm
The length and special sizes can be customized, As per 100% drawing
99%Alumina:
