00:00Hey everyone, so I went looking for 99.9% pure scandium metal for aerospace alloys,
00:05and here's the thing nobody tells you, real scandium is basically unobtainium.
00:10It's one of the rarest metals on earth, and any retail listing claiming aerospace-grade
00:14scandium at hobby prices is almost certainly mislabeled. So instead, I tracked down 5
00:20genuinely high-purity metals backed by thousands of verified buyers that actually show up in real
00:25aerospace alloys, lab work, and workshops. Let's go through them. First up, this 99.995% pure zinc
00:33ingot, a full kilogram for just $13.59. That's 5 nines of purity, which is honestly impressive
00:40at this price point, and with nearly 4,700 sold and a perfect 5-star rating, buyers clearly aren't
00:46disappointed. Zinc is a workhorse for casting, galvanizing, and alloy work. It's not scandium,
00:53but if you're casting or experimenting with alloys, this is the best value per gram on the
00:58whole list. Thirteen bucks for a kilo, that's tough to argue with. Next, a 100-gram pure chromium
01:05block for $8.20. Chromium is what gives super alloys their corrosion resistance and high temperature
01:12strength, so it's a legitimate aerospace player. This one sold over 4,600 times with a 4.8 rating.
01:20It's a clean, dense block, great for lab testing, element collections, or small DIY plating and alloy
01:26projects. If you want a genuine high-purity chromium sample that won't break the bank,
01:31this is the one most people reach for. Now here's the budget pick, another 100-gram chromium block,
01:38same 4.8 rating, but only $4.13. That's roughly half the price of the last one.
01:45Same element, similar purity spec, aimed more at students and university labs.
01:51If you're doing coursework, bench testing, or you just want chromium in your collection without
01:55spending much, this is the obvious buy. Just check the listing photos and seller details before you
02:01order, since it's the cheapest option here. Moving on, 99.99% pure tin ingot for $18.12,
02:09and this one's a little different. It's cast as a soft metal sphere, with over 3,500 sold and a
02:164.7
02:16rating. Tin is a classic for welding, soldering, casting, and crafts, and the spherical shape makes
02:23it genuinely fun to handle and display. Great for workshop projects where you need clean,
02:28predictable solder or a bit of tin for alloying. Yeah, it's pricier per gram, but the purity and
02:34finish are what you're paying for. And last but not least, magnesium ribbon, 99.95% pure,
02:42starting at just $5.94 for a roll. Magnesium is the lightest structural metal and a genuine
02:48aerospace staple. It also burns bright, which is exactly why it's a must-have in chemistry demos.
02:55Nearly 3,500 sold with a 4.9 rating, the highest on this entire list. Whether you're doing lab work,
03:02teaching, or you just want to see something spectacular, this is a fantastic cheap pickup.
03:08And that's the list. All 5 links are down in the description below,
03:13so go grab whichever one fits your project. If this helped you out,
