Which material for shieldings?

(1/3) > >>

Aldo22:
I am not sure if this is the right forum category.

I am looking for a material/sheet for shielding etc. which should be easily cuttable and to some degree formable (edges).
About the type that is used for these simple shields, e.g. in the NanoVNA (picture).
Is this aluminum or steel?

How thick should it be? I can't measure the ones I have, unfortunately.
Would something like this work (aluminum)?
Or steel?

Am grateful for advice.
Thank you!

Gyro:
It's Tin plated steel. It offers reasonable corrosion protection and good solderability. The traditional source is old food cans [Edit: hence the name 'Tin can']

Thank you!
Would that be something like that?

What thickness is still workable with scissors or knife?
Is 0.2mm already too thick?

Gyro:
Good question, I would think the thinner the better for scissors, the traditional tool is 'Tin Snips' (that name again), which are like really heavy scissors. If you're just prototyping / home project then thin brass or copper sheet is also useable, softer, and available from craft stores etc.

PartialDischarge:
There are proto kits to make you own shielding cans. I've seen this one but there may be others.
