Is there a blacksmith trick to determine this
on an actual handlebar?

Here is a web page [1] that attempts to answer
this question, and from skimming it I imagine
this is the best answer:

Take one piece of aluminium and one piece
of stainless steel and hold it in ur hand -
they must be the same size, you can feel
the weight different: aluminium is much
lighter, while stainless is much heavier.
Or a simple test, take a needle file, just
file on the aluminium and you see that
aluminium material can be removed easily by
filing away with a needle file while
stainless is much harder and you can't file
and remove any material on that piece of
stainless steel, in short stainless is the
heavier and harder material and aluminium
is the lighter and easily
deformed material.

Use a magnet.


Exactly. What could be simpler?

The only confusion would be if you'd run into non-magnetic stainless
steel handlebars. But unlike aluminum ones, stainless steel bars are
very rare, if not nonexistent.

I have one bike with aluminum handlebars, North Road style. I paid $7
for them during a bike shop's close-out sale. But you can get them he

They're not very exotic.
