High Thermal Shock Resistance Si3n4 Silicon Nitride Ceramic Rods
1 . Description
Extraordinary thermal shock, it can withstand up to1000ºC
It's easier to do precise machining, the tolerance can be 0.001mm
Chemical corrosion resistance under high temperature, except for HF and H3PO4
Extreme wear and abrasion resistance., much better than stainless steel
Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
2 .The specification of silicon nitride ceramic rods
| Optional material | Silicon nitride (Si3N4), Alumina (Al2O3), Zirconia (ZrO2), Silicon carbide (SiC) |
| Dimensional capability | Diameter range from 0.30 ~50 mm, length can be up to 2000 mm |
| Secondary process | Lapping, Fine grinding, Precision cutting, Tapping, Drilling and so on |
| Technical parameters | Diameter to be 0.005 mm, length to be 0.10 mm, roundness can be 0.001 mm |
| Roughness | The cylinder surface can be polished to be Ra 0.20 or better |
| Surface treatment | Diamond-like polished surface, Glazed, Metalized for ceramic to metal boning |
| Cosmetic quality | Smooth surface free of contamination, no deformation, and crack |
3 . Usage
Forming die parts (hot forging die, various forming)
Casting parts (low pressure casting, various metal melting furnace equipment)
Die casting machine parts (plunger, sleeve)
Welding machine (positioning pin for resistance welding, guide roller for steel pipe welding)
Parts of the powder squeezing machine (classifier, air squeezing machine, sand mill)
Wear-resistant parts (wire drawing machine guide roller, motor shaft, bearing, fishing tackle guide cup, traction winch)
Semiconductor manufacturing equipment parts (platform parts, linear motors)
