Are those Palladium contact wires ever magnetic?



I found a scrapped keyboard & saved the long sideways thicker wire thinking its 'the good wire'.
But threw away all of the long thin springy magnetic wires, one on each key, thinking "its magnetic so its not Palladium'....

Any idea on what the return is for any keyboards. They are cheap if you find them, no one wants them any more, just hard to find.
