Product Description

Silicon Nitride Heating Element Protection Tube
 

Silicon nitride is a man made compound synthesized through several different chemical reaction methods. Parts are pressed and sintered by well developed methods to produce a ceramic.The material color is dark gray to black and can be polished to a very smooth reflective surface.High performance silicon nitride materials were developed for automotive engine wear-resistant parts, such as valves and cam followers and proven effective. The very high quality bodies
developed for using in many severe mechanical, thermal and wear applications.

 

Silicon Nitride (Si3N4) Characteristics: 1 Good thermal shock resistance 2 Creep resistance 3 Low density 4 High fracture toughness 5 High hardness and wear resistance 6 Electrical resistivity

Silicon Nitride Typical Uses:

• Rotating bearing balls and rollers
• Cutting tools
• Engine moving parts - valves, turbocharger rotors
• Engine wear parts - cam followers, tappet shims
• Turbine blades, vanes, buckets
• Metal tube forming rolls and dies
• Precision shafts and axles in high wear environments
• Weld positioners
