      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.

    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

        Most cars are still steel. Source I work on cars in New England. So much rust, even on the ones with aluminum bodies, at least wherever it can touch a dissimilar metal and becomes a battery.

        And crucially the important parts that keep it from exploding (cylinder liners) and save you in a crash (crumple and bumper cores) are almost all steel. Because it deforms better with simpler engineering.

        See also iron brakes in most cars hardened steel bearings everywhere.

          I was referring to the engine block and pistons being aluminum. I assume chassis and many of the critical spinning bits are still steel or iron.

          It’s also mostly a shit post. I’m a machinist and I am surrounded by aluminum in funny forms.

            Yeah I’m mostly just shitting on it for fun too. But the pistons don’t work very long without steel rings, wrist pins and big end bolts.

            The problem is we have to bring copper, brass and other fancy metals in them though, because the all spin on oil cushion bearings. Unless we’re talking Babbitt bushings from the early 1900s.

    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

        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

      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.

      Pity it’s been suggested it’s a cumulative neurotoxin that contributes to Alzheimer’s disease. That’s the one thing I don’t like about aluminium.

    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!

      not to defend Alluminium (bleh), but that’s likely a production error, bad hydroforming, bad welds… at least it’s not CF!

        It was the early 90’s and Raleigh had a line called Technium. The tubes were bonded to the lugs. Not really welded. More pinned and “glued” I guess. The frame broke at either the top or down tube and there went the fork, and my buddy’s face. Screw aluminum. Steel has memory. I found that out the hard way. I’m far from a metallurgist. This is the extent of my elementary teacher brain. And a broken cf seat post is scary.

      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

      I love my steel bike, it’s great on the road, on gravel or for a quick grocery shop.

      I’m not gonna win any competition with it but it is honestly such a fun bike.

      And with care it should last forever.

    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’.

    Doesn’t most cheapo aluminum have iron mixed in to make it more affordable? I worked at a machine shop a couple of months and I remember the shitty castings downright having iron bubbles inside them

    aluminum is a great metal for making flashlights. Especially after anodizing it.

    It allows heat to be dissipated really fast too.

    But it is tungsten that reigns supreme:

    All the people here who bought this wireless tungsten cube to admire its surreal heft have precisely the wrong mindset. I, in my exalted wisdom and unbridled ambition, bought this cube to become fully accustomed to the intensity of its density, to make its weight bearable and in fact normal to me, so that all the world around me may fade into a fluffy arena of gravitational inconsequence. And it has worked, to profound success. I have carried the tungsten with me, have grown attached to the downward pull of its small form, its desire to be one with the floor. This force has become so normal to me that lifting any other object now feels like lifting cotton candy, or a fluffy pillow. Big burly manly men who pump iron now seem to me as little children who raise mere aluminum.

    I can hardly remember the days before I became a man of tungsten. How distant those days seem now, how burdened by the apparent heaviness of everyday objects. I laugh at the philistines who still operate in a world devoid of tungsten, their shoulders thin and unempowered by the experience of bearing tungsten. Ha, what fools, blissful in their ignorance, anesthetized by their lack of meaningful struggle, devoid of passion.

    Nietzsche once said that a man who has a why can bear almost any how. But a man who has a tungsten cube can bear any object less dense, and all this talk of why and how becomes unnecessary.

    Schopenhauer once said that every man takes the limits of his own field of vision for the limits of the world. Tungsten expands the limits of a man’s field of vision by showing him an example of increased density, in comparison to which the everyday objects to which he was formerly accustomed gain a light and airy quality. Who can lament the tragedy of life, when surrounded by such lightweight objects? Who can cry in a world of styrofoam and cushions?

    Have you yet understood? This is no ordinary metal. In this metal is the alchemical potential to transform your world, by transforming your expectations. Those who have not yet held the cube in their hands and mouths will not understand, for they still live in a world of normal density, like Plato’s cave dwellers. Those who have opened their mind to the density of tungsten will shift their expectations of weight and density accordingly.

    To give this cube a rating of anything less than five stars would be to condemn life itself. Who am I, as a mere mortal, to judge the most compact of all affordable materials? No. I say gratefully to whichever grand being may have created this universe: good job on the tungsten. It sure is dense.

    I sit here with my tungsten cube, transcendent above death itself. For insofar as this tungsten cube will last forever, I am in the presence of immortality.
