Why do they use tungsten and depleted uranium instead of tempered iron or steel?

Is it a weight issue or do they just not perform?

    Penetration scales with sectional density, penetrator length, and speed.

      Right.
      But again whats so inferior about tempered iron? (other than rust)

          iron (and steel) need a lot of treatments to be used properly.

          Lack of density and strength.

          isn't it overkill? a hit with any bullet is a casualty

        Density, moron. Iron and steel are about 7.8 grams/cubic cm. Tungsten is over 19.

          E-modulus isn't strength.

          If you're shooting at an unarmored human that's sorta kinda true-ish. But not everythign you may want shot in war will be an unprotected human. Tanks for example have proven to be somewhat hardier.

        If you'd ever picked them up and held them you'd immediately understand the difference. Imagine being hit with a wooden bat, then imagine being hit with a steel bat filled with fucking lead. it's all about density

        The hardening and tempering process you're thinking of works nicely on many steels, and does nothing whatsofuckignever to plain old iron.

    Retard, is this even a question? Its like asking why use metal fibers for tank armor instead of paper

    Interestingly China produces something like 99% of global tungsten, the US effectively has none and gets it all from China

      >the US effectively has none
      Not true, the US has hundreds of thousands of tons of tungsten deposits, there is just no reason to spend hundreds of millions of dollars to start mining it with first world labor rates when we can pay china/russia/vietnam who all have tungsten deposits and dirt cheap slave labor to work the mines.

      Oh yeah, Canada also has a fair amount of tungsten deposits, but again, it makes no sense to pay first world labor rates to mine it.

        What's not true, the US does buy all of its tungsten from CCP China which has almost 100% of global tungsten production market share for decades

          you didn't say that
          > China produces something like 99% of global tungsten, the US effectively has none

          You said the US effectively has none, which is patently false. They have tons, literally hundreds of thousands of tons, they just don't see any economic advantage in mining it since it's not exactly hard to buy on the open market at the moment.

          In a SHTF scenario where china and russia wont sell us tungsten there is nothing stopping either the US or Canada from starting up their own tungsten mining operations if it were deemed economically viable enough to do so.

            Canada has already started the process to open more tungsten mines.

    On top of density, depleted uranium alloys will not mushroom, but instead maintain its pointed profile as the sides of the projectile will shear off; called "self-sharpening".

    This only happens at relatively slow speeds, so you can have a very barrel-wear-efficient projectile.
    DU also burns.

    Tungsten must be alloyed, resulting in less density than DU, and will mushroom, but it is just as effective at ultra-high speeds

      DU also has to be alloyed (with tungsten funnily enough) to have the sectional density useful enough to be used as an armor penetrator.

        That doesn't make any sense. Uranium is plenty dense on its own. If they are alloying it with Tungsten it's not to improve the sectional density, it's to change some other properties.

          Pure U is dense, but has no structural integrity, you have to alloy it so it doesn't just powder upon impact

            It also starts burning if it comes into contact with oxygen and is an incredibly toxic heavy metal.

              The military doesnt care if it gives sandmorons cancer, if it means they get more performance out of the projectile.

                The military does care if it's difficult to store and handle, though.

          > A porous preform is made by sintering consolidated tungsten powder. The preform is impregnated with molten uranium such that (1) uranium fills the pores of the preform to form uranium in a tungsten matrix or (2) uranium dissolves portions of the preform to form a continuous uranium phase containing tungsten particles.

    1. Depleted Uranium is denser than all your shitty materials you just suggested
    2. Depleted Uranium adiabatically shears, whereas Tungsten and your shitty materials mushroom the penetrator as it goes deeper, and therefore slows it down and gives less performance.

      tungsten doesn't mushroom. It's far too brittle for that. It shatters, as your own pic shows.

    What type of WC is used in penetrators? it seems thiers different hardness levels.
    Also how would one order from a vietnamese manufacturer and ensure the dimensions were tolerable for handloading?

    Tungsten is like 7 times more dense than steel, and a 7.5 in hardness whereas the hardest you can get steel is like 7.
    The real GOATs have a tungsten carbide tip also, with a hardness of 9, helps start breaking up the plate
