Aluminium Sheilding - 3105-H14 Aluminum
Aluminium Sheilding - 3105-H14 Aluminum
(OP)
A product that we make is currently using '3105-H14 Aluminum' plate for shielding. The vendor wants to change it to '3003 aluminum'. Is there any properties that I should be worried about as far as shielding goes.
Also in both cases the Aluminum sheet will be Electroless Nickel Plated.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

There is an abstract available that addresses certain aspects of EN deposition on aluminum, particularly 3003.

Aluminium is an excellent EMI/RFI shield if it is grounded to your chassis. You need an electrical contact from your chassis, through the mounts, into your shield.
Is electroless nickel, as applied, conductive?
The problem, possibly, is that your aluminium grade is not good for plating. If the plating works, better plating is better. I know that the whole 3000 series of aluminium is difficult or impossible to anodize, not that you want to anodize.
A chemical film finish as per MIL-STD-5541 is conductive, and is good for shielding, regardless of aluminium grade.
