Choosing the right shielding materials for your specific application.
Selecting the right shielding material depends on several factors including frequency range, attenuation requirements, environmental conditions, and budget. This guide helps you make an informed decision.
| Material | Max Attenuation | Frequency Range | Best For |
|---|---|---|---|
| Copper | 100+ dB | 10kHz - 40GHz | RF shielding, SCIFs |
| Aluminum | 85 dB | 1MHz - 40GHz | Cost-effective solutions |
| Silver | 120+ dB | All frequencies | Military, critical apps |
| Mu Metal | Varies | DC - 100kHz | Low-frequency magnetic |
| Conductive Fabric | 60 dB | 1MHz - 10GHz | Flexible applications |
Copper or aluminum shielding provides excellent attenuation. Choose copper for highest performance or aluminum for cost savings.
Mu metal or specialty alloys offer superior permeability for protecting against power line frequency and similar threats.
Conductive fabrics work well for curtains, wraps, and irregular surfaces where rigid materials won't fit.
Aluminum provides good shielding at a lower cost. Consider coating thickness for required attenuation levels.
