Wireless charger by coil VS aluminum box

[qwertxx]

Hi

I would ask you for an opinion about my project.
I want to make charger by coil like this:

**broken link removed****broken link removed****broken link removed****broken link removed**

Whether it will work well if the box is made of aluminum?

No it wont work.

If you have a coil wound like you show and power applied or even a strong magnet handy try waving a piece of aluminum over the top of the magnet face and see what happens.
