What is the arm of the winter soldier made of?

There is no canonical source information on the alloys from which the winter soldier's bionic arm was made. Due to its properties, titanium-based alloys would be the most likely material for the exo armor of the cybernetic prosthesis.

SPECULATION

Given the Marvel Universe's propensity to make imaginary metals, we can deduce which metal it likely is from its properties in the movie Captain America: Winter Soldier.

We can assume that Hydra was developed by the best post-1945 scientists and is likely to be updated every time new technology becomes possible. Until 2014, it will consist of the best technology money can buy.

The arm gives the winter soldier superhuman strength at eye level or even more than serum-infused Captain America. The armor is finely structured with hardened coating protection technology.

  • The arm is super strong and still has an articular surface that can be removed if necessary.

  • Given the relatively thin coating of shielding metal, it has to be quite tough.

    • The arm blocked the fire of small and medium arms from small arms and assault rifles.

    • It has to be a metal hard enough to be hardened against gunshots.

Elimination round

  • Adamantium or Secondary Adamantium: Unlikely as it could be damaged. A prosthesis made from adamantium could not be damaged by any size portable weapon and would also withstand rounds of armor. (unless they were made of armor-piercing adamantium). I'm not even sure if there is adamantium in the MCU.

  • Carbonadium: No. While it has excellent damage resistance and is the next contender if you can't get adamantium. Unfortunately, carbonadium is highly radioactive and unsafe if someone is around for a long time. Since no one wears a hazmat suit while working on the soldier's arm, we can assume that Cabonadium is off the table.

  • Vibranium: Although Vibranium Not considered particularly harsh in the canonical Marvel Universe, it appears to be quite durable in the Marvel Cinematic Universe. Captain America's shield in the MCU is not made from primary adamantium, but from a vibranium alloy. The possibility that the arm was made (or coated) from vibranium is interesting, but unlikely given Howard Stark's claim that Captain America's shield was all of the vibranium in the world.

  • Titanium alloy: Our most likely candidate: Strong, light, durable, and tough. We know titanium alloys were used in the Canon Marvel Universe. The Android Jocasta was made entirely of hardened titanium alloys. It was as hard as any technology could make without extraordinary materials.

Titanium Alloy: This would be a good choice.It is a strong metal when used in steel alloys that can be hardened and, most importantly, would be relatively easy to secure.And it could still be a bit lighter than pure steel alloys.

  • Aluminum alloy: While there are aluminum alloys with strength comparable to that of steel, the advantage of using aluminum over steel would be the lower comparable weight to steel. The weakness is the lower defensive rating you would get from aluminum. It may be less likely to be an effective defense against larger ammunition projectiles without deforming.

  • Steel alloy : We know that steel alloys are common in the Marvel Universe. Some of the earlier Iron Man armor are made of hardened steel. Steel is usually the choice when weight is not an issue.

Given the speed and natural-looking movement, steel, while most desirable in terms of defense, is unlikely to be as fast as the winter soldier's organic arm, potentially affecting his combat capabilities.I suspect this would have been the most common material his arm would have been made from by the late 1970s.

Could considering the conductivity of the alloy help narrow it down? When Black Widow tagged him with one of their shock disks, it turned off his arm systems, but didn't seem to affect the rest of him in the way it was shown that the disks had incapacitated others, much like a tazer or stun gun.

I think its resistance to electricity was part of the arm's physical capacity. It had the ability to generate at least one electromagnetic pulse. I suspect it was hardened against EMPs and likely made resistant to electrical attack. I'm not sure if the special metallurgy would be beneficial if it weren't for a ceramic or non-metallic component.

It is highly doubtful that adamantium exists in the MCU, how closely it is linked to Wolverine. Another item on the comic shield is an adamantium / vibranium alloy that gives it the strength and impact resistance of both elements.

@Thaddeus "probably not in the face of Howard Stark's claim that Captain America's shield was the whole vibranium in the world". I interpreted this line in Captain America: The First Avenger as Howard Stark who said it was all YOU had, not the whole world. Avengers: Age of Ultron showed us that there is indeed more Vibranium in the world, as is the one to come Black panther Movie (most likely).

Of course there was more. I am only speaking at this moment in the story. I know Marvel's backstory on Vibranium.
