REFLECTOR: Primary wire

[John Tvedte]

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.  AWG-2 FatWire Manual.pdf<http://periheliondesign.com/fatwires_files/fatwiremanual.pdf>   on the page has the claims for it.  Supposed to have same current capacity as solid an half the weight.
