Product Description
Silicon nitride structural components carry loads, locate parts and provide wear-resistant interfaces in industrial equipment.
Custom supports, fixtures, guides and featured parts use the material's strength, fracture toughness and wear resistance. Low thermal expansion and good thermal shock resistance are useful where mechanical loading is combined with repeated temperature changes.
Supports, clamping points, holes and section transitions define how loads pass through the ceramic structure.
Product Features
- Strength and fracture toughness for load-bearing structures
- Wear resistance at mechanical contact surfaces
- Low thermal expansion for stable geometry
- Thermal shock resistance in cycling equipment
- Electrical insulation for suitable interface designs
Typical Applications
- Custom supports and fixtures in precision machinery
- Wear-contact and guide components
- Structural parts in thermally cycled industrial equipment
- Drawing-based load-bearing and locating components
