Why not flexi copper

Discussion in 'Mech Tech' started by Dub and Dubber, Aug 19, 2018.

  1. Why are metal fuel lines problematical? Metal piping seems to work OK on the brakes.
     
  2. The brake lines aren’t attached to something vibrating.

    Steel isnt the same as copper or copper alloys.

    It is why at the start of the Iron age, the guys with the work hardened bronze swords could still make mincemeat of the guys with soft iron swords... until somebody started quenching them in oil and roasting using animal skins to add carbon and nitride them...
     
  6. Been using 8 mm copper since I bought the bus 16 year's ago not had no problems with it

    I was "thinking aloud" picking up some doubters, or at least tales of them not lasting that long after all .... and if we're moving towards having to use fuels with more ethanol in them .....?

    ... so it's ALREADY work hardened? (bad for coping with vibrations) in the way that copper would BECOME work hardened because of the vibrations?
     
  11. Only if they're Bad Vibrations. Good Vibrations are much better. The Beach Boys wrote a song about them.

    Have I got the steel thing right though?
     
  13. Work-hardening any metal will make it become brittle.

    The bronze swords snapped too.
     
  15. That's why they developed the Uzi.

    Back to basics now knife crime is very depressing, but at least we haven't the gun laws of the States.

  17. my mgb has copper brake pipes with rubber hoses of course, and copper fuel lines from tank to electric pump and copper from pump to engine bay, then rubber hoses to the carbs to accommodate the engine movements. Copper is good and no corrosion or other issues in the 15 years I have owned the car.

  18. No corrosion, but it is more susceptible to work hardening than steel or Cunifer. Not sure why.
     
  19. Copper was used on most of the old bikes and people still run them, (lots of vibrations there) with no issues.
