Seems quite clear - Strucker spelled it out:
And he was maintaining it at a VERY specific temperature:
Which ties in with primary adamantium, which uses - you guessed it, Resin X and Resin Y at 1500 degrees Farenheit:
That adamantium, btw, withstood direct strikes from an enraged Thor, so...even IF it's secondary (no proof btw), that's still a beastly feat, to crush it with one hand using your fingers.

Wut. As Cable says:
He's literally ripping their heads off and scrunching them. They're explicitly said to be forged from adamantium. The heads and bodies and claws are the same colour.
And you are saying there's...zero proof? Gawd damn, lol. Why are you so insistent against the feat? First you say it isn't True adamantium, then I show you that's wrong, now you're saying it isn't adamantium at all?
