Ceramic Valve Ball In Material Of Silicon Carbide With Ø28 mm
Description of Ø28 Ceramic Valve Ball:
Our silicon carbide valve balls are made of highly purified, sub-micron silicon carbide material and sintered through pressureless sintering technology, so their properties are besser than the reactive sintered SSiC valve balls.
Why choose us:
At present, our company has two production lines specializing in the production of high-precision ceramic balls, and can produce customized GPS (Gas Pressure) and HIP (Hot Isostatic Pressure) sintered silicon nitride balls and zirconia balls. We can also produce ceramic bearing balls and calibration balls for high precision CMMs and etcs., whose accuracy level shall reach to G3, G5 and G10 or quality is equivalent to ASTM F2094 F2094M-08 grade I and II materials, and can also produce pressure-free sintered silicon carbide bearing balls and valve balls of various sizes and accuracy levels. Our producible size range of ceramic balls and ceramic ball valves is from 1.588mm to 60mm.
►Key properties of pressureless sintered silicon carbide |
♦ Max Temperature up to 1650℃ |
♦ Low density:3.15-3.18 g/cm3 |
♦ High strength |
♦ Low thermal expansion : 4.0 (10-6/℃) |
♦ High thermal conductivity:120 W/m°K |
♦ High hardness:2800 HV5 |
♦ High elastic modulus: 410GPa |
♦ Superior chemical stability,resistance to acid and alkali corrosion (incld. hydrofluoric acid) |
