Applications within the Projection Welding industry demand the toughest and most durable of materials.
Ortech, Incorporated is a worldwide leader in the development and production of advanced technical ceramics.
Silicon Nitride has an unparalleled track record in durability, providing a wear-resistant ceramic material to combat the rigours of any welding environment.
The effectiveness of Silicon Nitride can be attributed to the following unique properties:

• High wear resistance
• Increased life in service
• High quality ground surface finish
• High flexural strength values
• Non-electrically conducting
• Non-magnetic
• Resistance to weld spatter
• Precision engineered parts

Why choose Ortech Silicon Nitride Welding Location Pins?
Unlike pins coated with ceramic, Silicon Nitride offers a solid monolithic ceramic – so there is no thin layer of coating to break through in service and create wear. Longevity is increased many fold, reducing process down-time and improving product quality.

Hot Pressed Silicon Nitride

By hot pressing silicon nitride, one can achieve nearly zero-porosity. This leads to the exceptional mechanical properties as well as corrosion resistance even in high-temperature applications.Hot pressed available for ball bearings and for cylindrical Rollers bearings

Sintered Silicon Nitride

Sintered silicon nitride unique grain structure provides excellent mechanical properties for durability in mechanically rigorous environments.
