Austenite stainless is 300 series, usually non-magnetic but can be after
beaten into shape (work hardening).  You need to anneal your tweezers, not
run them through a demagnetiser.  It's only be very slightly magnetic
though, you can feel a slight attraction to a magnet.

400 series stainless steel is magnetic - that's what they make fridges,
microwaves & cutlery out of.  Cheaper & less rust resistant.

As others have mentioned most component leads are tin-plated steel/iron
these days.

Some places sell bamboo tweezers, or you can get a vacuum pen.  I like the
pen, there's fewer 'ping!' 'where did that go?' moments.
