Si3n4 Silicon Nitride Ceramic Rod High Thermal Shock Resistance

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 materialSilicon nitride (Si3N4), Alumina (Al2O3), Zirconia (ZrO2), Silicon carbide (SiC)
Dimensional capabilityDiameter range from 0.30 ~50 mm, length can be up to 2000 mm
Secondary processLapping, Fine grinding, Precision cutting, Tapping, Drilling and so on
Technical parametersDiameter to be 0.005 mm, length to be 0.10 mm, roundness can be 0.001 mm
RoughnessThe cylinder surface can be polished to be Ra 0.20 or better
Surface treatmentDiamond-like polished surface, Glazed, Metalized for ceramic to metal boning
Cosmetic qualitySmooth 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)
