once you have the material setup as you like it, open the library, switch to the material tab and save the material into your library. Then you can appy it to other objects by selecting the material group in the material editor and double clicking the saved material in the library.

 

for brushed aluminium replace the spot node with an FBM node.

In that nodes parameters are x scale, y scale and z scale.  If you want the brushed look to go left to right, make y and z scale really small. if you want it going up and down, make x and z scale really small. finally to get it going back and forward, make x and y scales really small. (This is assuming the object is not rotated in any way)

I dont have access to my computer today, so I am not 100% sure how accurate this information is, as its all from memory.  Again, I am happy to show you later. this time it will be a bit more of a wait. I finish work in about 3 hours.

 

EDIT

By the way, your render looks nice!  the material came out really well
