      People always argue that -num isn’t a legitimate way for the name of an element to end, but I never see you guys talking about Platinium.

        Because platinum is also a concept. Nobody has gotten an aluminum record, or an aluminum medal. Some metals have ascended beyond mere utility into superficiality. Aluminium isn’t there yet.

    Team aluminum all the way. A higher up where I work is obsessed with stainless steel, he gets these monstrous heavy duty tables made out of SS that hold objects 1/3 of their weight. Makes lab rearranging a nightmare lol.

      Aluminum is where it’s at, and where it is, is everywhere.

      Your cans? Aluminum. Your car? Mostly aluminum. Old wiring, you better believe that’s aluminum. Your fucking phone screen is aluminum, sand paper is aluminum, half the birth stones are all aluminum let’s fucking goooo baybee

        Weirdo types that decided they were in charge of naming things decided to name it Aluminium so it “matched” the likes of other metals like titanium, iridium, etc

            couldn’t pronounce “graphics”

            That’s not how acronym pronunciation works though. We don’t pronounce them based on the words they stand for, otherwise we would pronounce NASA, SCUBA, LASER, etc. differently. Both pronunciations have valid arguments so why can’t we just accept both and stop being weird about it.

    I can’t think of many things you encounter every day that just use straight iron. Only alloys that use iron

    Meanwhile, you’ll use very pure aluminum all the time

      Pure aluminium is only used when you need to have very little reactivity.

      General construction steel has >98% weight iron. Around the same as most aluminium alloys.

        Really now? I thought most steel had way more carbon & chromium/nickel/manganese than that. I guess I underestimate how little is needed to make iron no longer mushy.

        Uh, I hate to break it to you, but literally all the iron in the human body is either part of a protein or bound to other molecules. It’s not an alloy per se, but it isn’t exactly pure iron

      Sounds like aluminum is a loner and iron plays well with others. I’d bet there is still more iron encountered every day than aluminum even if the aluminum is pure and the iron is alloyed.

      Perhaps so, but one might argue that human tech relies more on iron than any other metal - because of its magnetic properties. We need iron to generate and manipulate electricity.

    As a former cyclist, steel is real. I’ve seen aluminum bikes fail (as in, break at the top and down tube)during a ride. Screw your aluminum!

      Aluminium doesn’t get stronger on the welds like steel does, it gets weaker. So if you screw them up, you end up with a two part bike

        While I agree, I do have to clarify that there is a fatigue limit, it’s mainly that the limit for steel increases so fast that few people are willing to put in the testing for billions of cycles to model ultra-high cycle fatigue

          Where is that limit supposed to be? The line does not flatten, unlike that of steel. Which is a flat line from 1 million to 1 billion cycles. During the same number of cycles, aluminium drops from 25 to 14 ski, a loss of 44 %. The article specifically mentions:

          Some metals such as ferrous alloys and titanium alloys have a distinct limit, whereas others such as aluminium and copper do not and will eventually fail even from small stress amplitudes.

            Head’s up, referring to it as a “limit” like your article did is incorrect. In engineering you have what’s called an S-N diagram, which plots out the average time to failure based on average cyclic stress. Basically, a lower avaerage stress results in a higher average life. Also, this plot uses a logarithmic scale for both axis, because then all of the plots are straight lines.

            For steel, the S-N diagram has what’s called the “knee”, which is where you have two distinct lines in the S-N curve: one horizontal and one at an angle, with the two intersecting at 1 million cycles. Referring to the knee as a limit (like in the article) is wrong because it’s not a limit; it’s the threshold where if you design a part to last beyond that (aka less cyclic stress than would get 1 million cycles) then it practically lasts forever.

            In reality, the part won’t actually last forever, since the S-N curve beyond 1 million cycles isn’t perfectly horizontal. It’s just that reducing your cyclic stress quickly increases your predicted life into billions or even trillions of cycles. This is known as ultra-high cycle fatigue, and it’s generally impractical to do all the testing required to model because each sample would take months to test on the low end. Plus, there’s little demand for such models in the industry, though there are a handful of PhD students and post-docs working on it

              Does that change anything regarding the discussion? If the limit is quickly so high that it is beyond reasonable time spans? In the comparison at hand, aluminium has no fatigue limit, steel does. They still use aluminium for aircraft etc. due to the superior weight savings.

                Yes, because the term “fatigue limit” makes lay people think the exact opposite of what is intended.

    Back in my younger days I joined a flat earth gang. Real fun guys. It was mostly just a dudes hanging out together, talking shit, and doing petty crimes.

    One day we come across this dude and he starts going all in on us and how stupid we are. Shows up some stupid video of some nerd debunking us and talking shit to us. Darnell, one of the guys in the group is getting a bit agitated but this dude keeps talking shit to us and calling us dumb. Next thing you know Darnell sucker punches the guy and a couple of the other guys starts wailing on the guy. I joined in too because I wanted to support my friends. The last thing the guy heard was Darnell saying, ‘take his ass to the edge’.
