"stainless steel zinc alloy"......?
It's either one or the other.
The weak point on micro-USB cables isn't the actual cable in any case. It's the blasted micro-USB connector itself. They break if you look at them funny. That's supposed to be one of the MAJOR advantages of the USB-C connector — it's supposed to be much more robust than micro-USB.
FavsThen they should say that. But "stainless steel zinc alloy" is intrinsically meaningless. It's like talking about wooden glass.
(And frankly, I would not use the word 'durable' to describe zinc alloy. Zinc alloy parts are used not because they're good, but because the materials and tooling are cheap. Albeit they are, if properly designed for the material, possibly somewhat better than plastic. But the weak point is neither the connector housing nor the cable anyway, so it doesn't really matter.)
FavsThe real weakness of the micro-USB connector is where the protruding connector portion joins into the shell. That joint is very weak. I'm given to understand USB-C is somewhat stronger in this regard. (So is USB 3.0, but it never really caught on.)
