Effective EMI Shielding Contributes Industries Development

Shelter is critical important in military to be used as weapons and equipment system, command and communication center and high shielding shelter, stealth shelter, bulletproof shelter, explosion-proof shelter and so on. But the traditional metal shelter has been replaced with composite materials.

Composite shelter can reduce 50% to 70% weight for Maneuverability. But it needs to be added shielding material (micro expanded metal).

High precision expanded metal mesh (micro expanded metal mesh) has light and integrated structure, uniform surface, stable continuous opening and customizable flexibility. The most important is, the precious expanded metal has excellent EMI shielding performance to supply excellent shielding performance and make up for the deficiency

Besides, the micro expanded metal has been used as shielding material in aerospace, electronics and other fields.

Materials

EMI shielding mesh is available in various materials, including copper, aluminum, nickel, Monel, etc. Copper is the most widely used type. And all our copper content of micro expanded metal shielding mesh is ≥99.7% (economical) and ≥99.9% (best shielding performance) and all of them comply with RoHS standard.
