Summary of responses to this:,

AL>I saw a product called ALUMALOY advertised on TV.    It is a "welding
AL>product" for aluminium which melts at 728 degrees F and uses no flux.
AL>According to the ad it can be
AL>drilled and tapped and is "stronger" than the aluminium base metal.
AL>Among other things the ad showed them repairing an aluminium ladder and
AL>canoe with it.

AL>I can imagine many antenna projects for this stuff-- if it is as good as
AL>it seems.  Has anybody actually used the stuff?   Or is it another magic
AL>product that doesn't work.  At $45 for one pound of rods, it may be
AL>quite affordable as well as useful.

AL>The only spec I was able to copy down was a shear strenght of 31,000
AL>psi.

AL>The company that offers this is  Wendon Researct at 1-800-917-9353.


Several people have uses similar stuff.  Seems to work in their
experience.

It's really called brazing since the melting point of aluminium is not
reached.
