How to Design with Hexoloy SiC Materials

Our design engineer teams have worked together with manufacturing for the last 30 years and have put together the important points for designing with ceramics.

10 Geometric Designs to Avoid with Hexoloy SSiC:  Remember, Ceramics hate sharp corners

1.  Square Edges	Recommended / Not Recommended
Edge chamfering is the most important design consideration when using non-ductile materials.  Just remember, Ceramics hate sharp corners.  Our application and design engineers can recommend an appropriate material radius, depending on your application.
2.  Internal Grooves
Avoid inside diameter grooves or notches. It is much more economical and effective to utilize the properties of Hexoloy and grind grooves or notches on the outside.
3. Thin Flanges
Avoid thin flanges and sharp contact areas.  Remember, Ceramics hate sharp corners. Use generous radii for fillets at all intersecting surfaces to minimize point loading conditions.
4.  External Projections or Keyways
Avoid external projections or locating tabs due to stressful locading points at the sharp corners. In addition these features can be expensive and eliminated if designed with notches slots or grooves.
5.  Undercut Geometries
Avoid under-cut geometries.
6.  Loaded Notches or Grooves
Avoid notches or grooves which can interfere with bearing loads. Notches should be placed in the unloaded position. This feature also assists in keeping wear debris away from the bearing surface.
7.  Blind Holes or Slots
Avoid notches or grooves which can interfere with bearing loads. Notches should be placed in the unloaded position. This feature also assists in keeping wear debris away from the bearing surface.
8.  Nominal Sizes Bolt Holes
Avoid notches or grooves which can interfere with bearing loads. Notches should be placed in the unloaded position. This feature also assists in keeping wear debris away from the bearing surface.
9.  Assembled Protrusions
Avoid notches or grooves which can interfere with bearing loads. Notches should be placed in the unloaded position. This feature also assists in keeping wear debris away from the bearing surface.
10.  Bearing Diameters
Avoid bearing lengths exceeding two time the inside diameter. Instead, use two or more bearing components.
