REFLECTOR: Primary wire

[Al Gietzen]

Am I confused here?  Are we talking about using aluminum (or copper clad
aluminum), that is subject to work-hardening and fatigue fracture under
vibration, in order to save maybe 1/2 lb on a 1400 lb airplane?  MIL spec,
tefzel insulated wire is readily available, and not expensive in the scheme
off things.

Well... a couple of reasons come to mind...

 

1) Most airplanes are tractor configuration - and the weight savings is
minimal in that configuration - 4 AWG can be used - for our pushers it's a
different story.

2) Cost - the stuff is more expensive - in experimental - welding wire is
pretty low cost.

3) Not been that readily available (or not knowing that it exists)- Eric is
making it available, and now through Stein.

5) People question using aluminum wire - even though this is copper
coated....

I am not a chemist or a metallurgist, but if this stuff is as good, or even
better, why isn't in wider use?  I would never want to re-fish my primary
battery to starter cables.  .just my humble opinion.or fear of the untested
for my own needs as well as re-sale one day which I hope is very far off.

This is the link to some primary wire which is copper clad aluminum, 40% to
50% lighter than solid copper.
<http://periheliondesign.com/fatwires_files/fatwiremanual.pdf> AWG-2 FatWire
Manual.pdf   on the page has the claims for it.  Supposed to have same
current capacity as solid an half the weight.
