Apply alpha values from one image to another?

In one image the circle has a few pixels around the perimeter that fade to transparent (barely noticeable at first, and gradually fading more until the last pixels at the very edge of the circle are almost completely transparent). 

The other image contains only completely solid pixels (within the circle), and completely empty pixels (outside the perimeter).

Is there a way to apply (just) the alpha values from the first image, to the second one? (so the second one also fades gradually to transparent around the perimeter)

Thanks for any help!

• Open the first image (the one you want to change)
  
• File > Open as layer the fading circle
  
• Drag that new layer under the initial layer in the Layers list
  
• Right click the initial layer, Edit Layer Attributes and set the Composite mode to Clip to backdrop
  

If there are other layers, just put these two layers in a group by themselves, the resulting group will behave like a single layer
