Why would anyone want to use aluminum for a mast?  Rust resistance? 
Lightweight? Flexibility?  None of these are necessary characteristics of a 
mast.  The toughest aluminum alloy made doesn't come close to most steel 
alloys.  I recall back in the 70's a certain ham(a WB9) decided to use 
aluminum to stack some  beams.  To stiffen it up, he drove a hardwood dowel 
into the mast.  6 months later the top half broke off in a wind storm and 
came right thru his kitchen roof.  True story.
