I have a multi-part project with all the same materials. When I copy the object, it creates another material with the same assets, but a different name:

enter image description here

How can I delete them all and use the same material for all objects?

You should duplicate objects with Shift + D instead of Ctrl + C and Ctrl + V. This way it won't duplicate Materials.

But if you still want to duplicate objects like you did before:

You'll need to delete the unwanted Materials, all but one and then link that to all the other objects.

And how to do that:

  1. Go to the outliner on the top rigth (the place with your Objects, Cameras, and Ligths) and on the dropdown choose Blender File
  2. Navigate to the material folder and select unwanted the left click and choose delete (here X will not work like on the rest of Blender)
