Product Description
Whether you’re teaching your kid the periodic table or want to show off your nerdy side, these CrowdLabs Elements blocks are an interesting way to get up and close to some of the more common metals. Each cube measures an inch wide and features engravings of the periodic symbols, the number, atomic number, and atomic weight Read More
Looking at the materials I'm a bit baffled.
For example: Why are they using 6061 aluminium? 1000 series aluminium can't be that hard to get and it's probably cheaper than 6061. It makes more sense to me to have more of the element on display... on display. Same goes for Titanium but I give them a pass here because I don't know how hard it is to get. Now I know that pure iron is hard to get nowadays, but "cast iron" is a lot closer since it's a eutectic combination of iron and carbon (about 4.5%). It'll also develop a really rad patina as it oxidizes. Maybe they opted for 303 because it's cheap and won't oxidize as fast? Also: anyone know what Zinc alloy it is? The rest of them are specified but if I'm going to teach anyone about elements I'd like to know what's there.
Aluminum – Al: 6061 aerospace grade aluminum (96–98% aluminum)
Titanium – Ti: Aerospace grade Ti-6-4 titanium (90% titanium)
Iron – Fe: 303 stainless steel (80% Iron)
Copper – Cu: C110 (~99% copper)
Tungsten – W: High purity tungsten-carbide (92–94% Tungsten)
Zinc – Zn: Zinc Alloy (95% Zinc)
Magnesium – Mg: AZ31B Magnesium Alloy (97% Magnesium)
Unfortunate that I'm late to the party and the 7-piece is sold out. Otherwise, would've impulse bought.
I wonder how it would look if there were a mirror polished version...
Purchased these back on indiegogo, and the most recent late last year for the additional cubes making it a 7 piece. Very cool set on the bookshelf. At the time, they offered coatings and non coatings. I opted for the non coated ones, which allow patina to occur over time. The only disadvantage - it becomes a little difficult to read some of the numbers over time. But also a great characteristic.
