Does it matter if the bar is 6061 or 2026 or some other aluminum?

I chose to mount my battery ground [-] cable to the main longeron. My decision is based on the fact that this is the only longeron that goes all the way to the firewall. That means that it will reach my "forest of tabs" ground block [mounted on firewall] going through the minimum number or riveted connections. It also does not require drilling any extra holes into the longeron. I just use longer rivets there. See
