<VV> COPPER? brake lines?

Quote - Properties of Copper-Nickel Brake Tubing

The copper-nickel alloy used for brake tubing typically contains 10% 
nickel, with iron and manganese additions of 1.4% and 0.8% respectively. 
The product conforms to ASTM B466 (American Society for Testing and 
Materials), which specifies dimensions, tensile strength and yield 
strength. Formability and internal cleanliness conform to specifications 
SAE J527, ASTM A254 and SMMT C5B (Society of Motor Manufacturers and 
Traders). Also, the alloy meets the requirements for pressure 
containment, fabrication and corrosion resistance for ISO 4038 
(International Standards Organization) and SAE J1047.

Users of copper-nickel brake tubing in addition to Volvo [since 1976] 
include world-class vehicle manufacturers like Rolls Royce, Lotus, Aston 
Martin, Porsche and, most recently, Audi. Copper-nickel is also used in 
military, fire fighting and other heavy vehicles. - end quote

It is not new stuff.  It has been available in the US since 1991 when I 
started using it on my Abarth 750 GT. I have been using it for fuel 
lines, lately.
