Black Silicon Nitride Zircona Threaded Ceramic Welding Pin For Nut Welding
1 . Descriptions:
Silicon Nitride Si3N4 Ceramic is one kind of technical ceramic materials which has good comprehensive properties for different applaictions.It mechanical strength can be kept up to 1200℃.Its hardness and wear resistance performance ranks high among all technical creamic materials.Its has high electrical resistivity,high dielectric constant and low dielectric loss,is a choice for electrical insulation.Futrthmore,it has good chemical stability and resistance to oxidation.
2.Application:
Bearing balls and rollers
Cutting tools
Valves,turbocharger rotors for engines
Turbine blades
Diesel engine glow plugs
Molten metal handing
Thermocouple sheaths
Welding jigs,fixtures and nozzles
