I see you can buy Cupro-Nickel brake tubing as apposed to copper. when replacing tubing on cars I have always used copper. are there any advantages to using this cupro-nickel stuff? what other compounds are available?

thanks

Copper, cupro nickel (kunifer) and steel are the 3/16" solid pipe used on cars. The Kunifer is accepted in all EU countries as a replacement for steel but copper is not as it work hardens if it moves and may become brittle.
