It also identified copper nickel alloy c70600 tube as outstandingly superior to conventional steel brake line tubing in laboratory salt spray exposure burst tests. Otherwise steel lines will preform for many years.

Copper brake lines vs steel. Wrapped brazed steel is the norm for brake lines. Copper and four copper alloys also out performed the double wrapped steel tubing in the tests. This means that all the road salt and grime you pick up in the winter is ineffective at rusting the outside of the tube. One thing to remember brake fluid dot 3 4 will absorb moisture most reference material claims between 1 2 per year. Cunifer copper nickel brake line is corrosion resistant on the. Normal steel brake line is coated in a corrosion resistant material.
Stainless tubing is harder to bend and double flare. The moisture in the brake fluid rust metallic parts and will corrode aluminum. There is no saturation point in therory it will absorb all the water you can add to it. Moss may sell copper brake lines but ill bet they also sell that stuff that looks like copper but is far stronger and more resilient. Catastrophically is the technical term.

The trouble is that they dont fail slowly like steel they fail suddenly. Plain copper tubing will not take the pressure of brake fluid. Theres a copper coating on the inside of the tubing too. Cunifer copper nickel brake line is corrosion resistant on the outside. The exposed conifer copper nickel brake line is still 887 copper. This will double flare and bubble iso or single flare very easily.
Theres a lot more copper in a steel brake system than just your banjo washers. If this material fades or is scratched the plain steel line underneath is exposed and will rust.
