F-60 Beryllium Foil and Sheet — Technical Specification
PF-60 grade beryllium foil and sheet is available as flat stock in a standard thickness range of 12 µm to 10 mm. It can be supplied pre-cut into custom shapes, including rectangles, discs, and other geometries.
Thickness Range
-
Standard Range: 12 µm – 10 mm
Integrity Grades
PF-60 is available in three integrity classifications, each suitable for specific application requirements:
| Grade | Thickness Range | Description |
|---|---|---|
| Vacuum-Tight | 12 µm – 10 mm | Leak-tested and certified for vacuum environments |
| Optically-Dense | 12 µm – 10 mm | Blocks all visible light under high-intensity testing |
| Filter Grade | 12 µm – 10 mm | Supplied as-is; no optical or vacuum performance guaranteed |
Grade Specifications
✅ Vacuum-Tight
Each unit is leak-tested using a helium mass spectrometer.
Leak rate: ≤ 1.0 × 10⁻¹⁰ Pa·m³/sec of helium.
✅ Optically-Dense
No light transmission is permitted when the foil is illuminated with a high-intensity light source focused on one side, and observed from the opposite side in a darkened environment.
⚠️ Filter Grade
Material is delivered in its as-manufactured condition.
No guarantee of vacuum tightness or optical opacity.
Recommended for non-critical or filtration-based applications.
