The answers below are intended for early material selection and project discussion. Real-world shielding should be validated in the finished assembly under the intended test conditions.
Why are copper and nickel commonly used together?
Copper provides high electrical conductivity, while nickel can improve surface durability and corrosion resistance in many conductive textile constructions. The exact behavior depends on plating thickness, substrate and environment.
Why use silver-plated fabric?
Silver offers very high electrical conductivity and can be useful when very low resistance, flexibility or specific textile properties are important. Cost and environmental compatibility should also be considered.
Is silver always better for EMI shielding?
No. Material selection should consider the complete application. Copper/nickel fabrics can offer an effective balance of conductivity, durability and cost, while silver-based materials may be preferred for certain low-resistance or specialized textile applications.
What environmental questions should buyers ask?
Consider humidity, salt exposure, temperature, skin contact, washing or abrasion, galvanic compatibility and whether the conductive surface will contact other metals.
