Cunifer tubing is an outstanding choice for brake and fuel lines and is considered the "elite" material in the modern extreme performance and luxury car world today. Several manufacturers use cunifer tubing exclusively and many of the top-tier custom builders around the country use it daily. It is equally corrosion resistant as stainless and when polished is difficult to tell the difference between it and stainless. Unless you have a desire for the specific aesthetic appearance of stainless, cunifer is the best choice from all other mechanical perspectives (ease of flaring, ease of bending, no worry of cracking at the flare and/or work hardening, more vibration resistant, etc.) and it can be "worked" with conventional flaring tools, benders & cutters with far greater success than stainless in the average home shop. Beyond that, it's actually kind of "fun" to work with too!
