| Bone 410 |
| UL File No.: |
E48013 |
| ASTM Spec: |
ASTM D-710, Bone |
| Military Spec: |
Mil-F-1148, B-H |
| NEMA Grade: |
Bone |
Properties
Hardest and densest grade made. Best machining properties and very high resistance to wear and abrasion. Great
mechanical strength. This grade is tougher and denser than the commercial grade, but not as well suited to bending.
Applications
Recommended where difficult and extreme machining operations are required. Ideal for noiseless gears, cams,
cutting blocks, thrust washers, terminal blocks and railroad joint insulation. |
Thickness Range
0.030" to 4"
Note - Thickness over 0.093" is
Laminated Built-Up Fibre.
