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

Material Selection Guide

High-Frequency RF (1MHz - 40GHz)

Copper or aluminum shielding provides excellent attenuation. Choose copper for highest performance or aluminum for cost savings.

Low-Frequency Magnetic Fields

Mu metal or specialty alloys offer superior permeability for protecting against power line frequency and similar threats.

Flexible Applications

Conductive fabrics work well for curtains, wraps, and irregular surfaces where rigid materials won't fit.

Budget-Conscious Projects

Aluminum provides good shielding at a lower cost. Consider coating thickness for required attenuation levels.
