Aluminum with Steel screws
Aluminum with Steel screws
(OP)
We have 1/16" Aluminum sheeting screwed with steel self taping screws. The product gets heated 160°C maximum in a 50-70 % humidity environment. We are wondering how long (very approx.) could the thread hold the screw in place without being all "eaten up" by corrosion.
Thank you

RE: Aluminum with Steel screws
Do you mean steel presumably zinc plated, or stainless steel.

In fact we rarely threaded into aluminum at all, usually helicoil or similar.
On at least one design I remember using zinc plated steel pins in aluminium because of concerns over using stainless.
They lasted pretty well in a salt spray test, both with plain and anodized aluminium.
Of course this isn't threads where there are more traps etc so I guess I don't really know.
Sorry

If Aesthetics is a concern then in your environment zinc plated may be a concern.
