NSiC High Temperature Thermocouple Protection sheath For Molten AL
| ine Si3N4 bonded SiC High Temperature Thermocouple Protection sheath is a sort of structure ceramic material, NSiC product is shaped by casting with the composition of high pure SiC and Si powder, and sintered through nitrified reaction. NSiC has higher strength than RSiC and has excellent oxidation resistance. Maximum working temperature is 1500deg.In addition to its structural properties, NSiC has excellent wear properties and is resistant to corrosion and erosion by molten metals. So High Temperature Thermocouple Protection sheath can be used in direct contact with molten aluminum, zinc, copper, magnesium. NSiC has been successfully used for protection tubes for temperature measurement. NSiC offer many engineering property levels that are not found in other refractory materials, such as high strength at using temperature, excellent load bearing strength and resistance to chemical and abrasive attack. Characteristic Of High Temperature Thermocouple Protection sheath : 1. Excellent oxidation resistance 2. Good wear resistance 3. Excellent corrosion resistance 4. High temperature flexural performance 5. Excellent load bearing strength The Data Sheet Of High Temperature Thermocouple Protection sheath Bulk Density: 2.75-2.82g/cm3 Porosity: 10-12% Compression Strength: 600-700Mpa Bending Strength: 160-180Mpa Young’s Modulus: 220-260Gpa Thermal Conductivity: 15W/MK Thermal Expansion α（20-1000℃）: 5.0x10-6k-1 Max. Working Temperature: 1500℃ Si3N4: 20-40% SiC: 60-80% |
