Which one is more durable?

Captain America Shield.
Diana Bracers (pre reboot version).
Thor hammer.

If possible, rank them.

Both the shield and Mjolnir have been broken whereas the Bracers have not(to my knowledge)

molecule man would prolly say caps shield

Bracers
Shield
Hammer

Agreed.

Seeing as how Uru was easily scooped out of a mountain by Thor after Mjolnir broke, it's a mix of the material and the enchantment that makes it so strong.

1st= Diana's bracelet[made by the skin of an ancient olympian goat[aegis wich had undistructible skin] n was handed over to her by zeus after zeus strenghten it with is lightening] 2nd=Thor's hammer was made by the dwarfs of uru n can survive heat up to 5 times the sun without a scratch 3rd captain america's shield is made of vibranium which is the toughest metal on earth

Problem is that the shield is often used for the Worf effect.

And no, its not just made of vibranium. Used to have iron and adamantium in it, now it also has uru.

I'd say that the bracers are the more durable.

After that, i'd say the shield, and finally, the Uru hammer.

If my memories are ok, Uru hammer = 1st grade adamantium as far as durability goes, but I'm not sure.

"Experimental iron alloy" OR adamantium depending on the writer. Vibranium part under every writer.

It has uru mixed in now, too... (edit: you already posted it, sry)

Bracers
Thor's hammer
CA Shield

But before the last ten years it was
Bracers
CA Shield
Thor's hammer

Cap's shield has lost stock these recent years.

You mean because Serpent broke it?
