-rant- chinesium wires

Cursed to the 100th generation be they who invented wires made from chinesium.
I was trying to quickly cobble up something and used a few of those "dupont" connector breadboard wires i had laying around. the kind that come as a ribbon cable. i needed the female part on one side and simply want some switches on the other side. Quick hook-up i thought.
I tried soldering and it didn't go well. The solder did not "stick". I thought maybe the solder had gone bad ( flux goes bad... and this was very old solder roll ).
Maybe those wires were corroded.. so i dipped them in agressive rosin flux i had laying around. No avail. They kept breaking off and the solder was all blobby around them.
Turns out these things are made from aluminum !
I stripped several others and some of them looked like copper, but that turned out to be plated on... they too did not solder properly. I have no idea what that stuff is. i'll call it chinesium.

What drunken retard has come up with this chinesium alloy ? I spent two hours trying to solder 4 wires. In the end i collected all those things i had laying around and tossed them in the garbage can. never again.  I'm not going to delve into those knock-off "dupont" connectors.

Zoli:
It's called "Copper-Clad Aluminum Wire"; once you've burnt down the copper, is useless.
Here's an US made: https://www.rfsworld.com/pim/product/html/LCF12-50J (core conductor).

A bean counter no doubt.

Reasonably OK for intended use - but obviously not for 'extended' applications.

lol buy the crimp tool its like ascending to a higher plane of existence its like becoming the q of breadboards
