It's much more chemically reactive and less springy than copper, and more prone to fatigue. I've heard the newer alloys address this problem at least partially, but it was banned from most residential wiring applications for good reasons after a lot of houses burned down. permalink fedilink source parent hideshow 1 child comment replies: [–] Doomsider@lemmy.world 5 points 4 months ago And houses are known for their "movement".

I don't trust corner-cutters to engineer around these potential hazards. We're gonna see these Teslas light up like fireworks in a few years. permalink fedilink source parent hideshow 2 child comments replies: [–] dgriffith@aussie.zone 9 points 4 months ago (1 child) If it's for general vehicle wiring it'll be mayhem. If it's chunky busbars and such in the battery modules and drive motors... maybe not so much. permalink fedilink source parent hideshow 1 child comment replies: [–] SpaceNoodle@lemmy.world 4 points 4 months ago Yeah, would probably be fine for a bus bar.
