What is Conductive Metallic Foil ?
Conductive metallic foil is a thin-sheet metal material used for EMI/RFI shielding and electrical grounding in electronic assemblies. It combines high electrical conductivity and structural thinness to form a barrier that reflects or directs electromagnetic energy away from sensitive components.
Aluminium Foil
Aluminium foil offers strong conductivity, corrosion resistance, and effective EMI shielding at frequency ranges where lightweight and cost-effective solutions are required.
Nickel Foil
Nickel foil offers high conductivity in the planar (X/Y) direction, and insulation or specialized properties in the through-thickness (Z) direction. Its oxidation resistance, high temperature durability, and recyclability make it ideal for advanced EMI/thermal applications such as foam wraps and tight-space shielding.
Copper Foil
Copper foil provides superior electrical and thermal conductivity, making it highly effective for EMI shielding in devices such as laptops, smartphones, communication equipment, and battery systems.
Core Features & Benefits
High electrical conduction for effective EMI/RFI reflection and grounding
Low profile and thin gauge enabling compact, lightweight design
Good thermal stability and long-term reliability in demanding environments
Flexible metal foil formats that can be die-cut, laminated or used as tapes
Galvanic compatibility options for multi-material assemblies
Applications
- Temporary gap sealing for EMC testing
- PCB and module shielding
- Cable and harness shielding
- Shielded enclosure seams
- Custom die-cut grounding pads
- Device chassis grounding
- Battery and power module protection
- Communication equipment shielding
- Data center and server enclosures
- Automotive electronic assemblies
