While I can get 6061 aluminum, 303 and 304 stainless steel, and 360 brass and some bronzes locally (Boston area) from MetalSource's (Admiral Metals) Woburn site, they don't carry such things as 12L14 (and 1018 for that matter), and I haven't found a comparable local ferrous supplier for other than A36 (structural) alloy, so I may have to buy online. (I got the last batch from McMaster-Carr).
I've found three major online vendors (in addition to McMaster):
Where do people get 12L14? Which is best, and why? Metal Express, Metals Supermarket, and Metals Depot. Any other good choices?
