metals that retain a high order of ductility and resistance to brittle fracture down. to very low temperatures, and a much larger class of metals that, at some temperature. or in some range of temperature, undergo a transition from ductile to brittle.behavior. As pointed out above, the temperature level where this transition in fracture behavior. occurs is influenced by the test conditions.
If you are a moderate vaper, whereby you vape fairly consistently through most of the day, but only take a couple drags each time, your coils should last you about 14 days or so. If you are a very light vaper, where you take a few hits here and there throughout the day, your coil could last you 3 weeks or so.
sorry, this has been archived and can no longer be voted on. My MPT2 coils can last anywhere from 4 weeks to 1 week depending on the juices that I use in the tanks. I get more time out of my coils the less sweet and less dark the juice is. I tend to use sweeter, darker juices so my coils usually last about a week. Menthol and light, fruity juices tend to last me about a month.
