My Land-Rover had cupronickel brake lines on it when I bought it. It
survived lots of panic stops, including dry pavement wheels locked
stops -- close to 30,000 miles worth of use as a daily driver, plus use
in off-road. When I upgraded to a boosted dual circuit system, I made
lines out of plain old US 3/16" steel brake tubing. I had problems
with the lines galling to the tube nuts, and had to cut a couple lines
to replace wheel cylinders. Doesn't matter a bit how long the lines
are going to last if you have to cut them off to replace wheel
cylinders.

Volvo, Porsche and others supply vehicles with cupronickel brake lines.
