Product Description
Silicon Nitride Ceramic Locating Pins
Silicon nitride positioning pins are precision components made from superhard silicon nitride ceramics, offering exceptional performance characteristics for demanding industrial applications.
Key Performance Advantages
- High hardness rating of HRA93, second only to diamond
- Exceptional wear resistance with 10x longer service life than standard pins
- Non-conductive and non-magnetic properties
- Non-adhesive to welding slag and molten metals
- Excellent thermal shock resistance
Projection Welding Applications
Specifically designed for welding metal nuts to precise positions on metal plates. The insulating properties prevent unwanted current flow during welding, eliminating sparks that cause pin wear and workpiece damage. This eliminates the need for additional through-hole processes and improves workpiece quality and pass rates.
Performance Comparison: Silicon nitride projection welding pins deliver 70x better cost performance compared to steel positioning pins.
