Would different materials effect the shielding efficiency? such as iron, silver, copper ... etc.
I would like to know on which materials are better on shielding efficiency.

Do you have any suggestions?

Since the case of iPhone is metal, would iPhone be already safe to block most of RF during usage on holding area?

Do you have any suggestions?
Thank you very much for any suggestions (^v^)

Interesting question. Because part of the iPhone's aluminum body is being used as an antenna to propagate the radio signal, it doesn't block it. However, metal cases do effectively block radio waves, and therefore may degrade your signal quality.
