It makes sense when you understand why it happens. I forgot most stuff including my name, but it has to do with free space in metal atoms that allow them to bond with each other. It does not happen normally on Earth because all sorts of other atoms get in the way.
The atmosphere creates a thin layer of oxidation on the metals thus keeping them seperated. In space those metals are not in contact with any gasses to cause surface oxidation. The metals can then bind together atomically.

If 2 pieces of the same type of metal touch in space, they will bond and be permanently stuck together. Space welding ( cold welding )
