Silicon Nitride Si3N4 Ceramic Centering Pin/Location Dowel Pin for Automobile Welding

1 . Descriptions:

Silicon Nitride Si3N4 Ceramic is one kind of technical ceramic materials which has very good performance in high temperatrue, its mechanical strength can be kept up to 1200℃. Its hardness and wear resistance performance ranks high among all technical ceramic materials. It has high electrical resistivity, high dielectric constant and low dielectric loss, is a choice for electrical insulation. Furthermore, it has good chemical stability and resistance to oxidation. As a result, silicon nitride ceramic has the best comprehensive performance and most wide application in high temperature field.

2 . Applications:

Bearing balls and rollers

Cutting tools

Valves, turbocharger rotors for engines

Turbine blades

Diesel engine glow plugs

Molten metal handling

Thermocouple sheaths

Welding jigs, fixtures and nozzles
