TUOFENG 12 Gauge Electrical Wire 20 Feet [10 ft Black and 10 ft Red] Tinned Copper Wire Stranded Wire - 12 AWG Silicone Wire - Flexible Silicone Wire Works Well for RC car, Drone

As advertised

Just what I needed for some high temp prototype work. Very flexible and it can handle the heat.

Quality seems good. It was easy to strip. Very flexible functions very well. Easy to use. Now the copper content I don't know, but i can say it works for my Newport nk180 kayak motor without any issues.

After many years of usage, and just plain sitting on the shelf, test lead wiring becomes brittle over time and the insulation deteriorates. This wire fills the bill, if you don't mind unsoldering the original wire leads from the test lead connectors and resoldering the new wires on. You need "superflex" because regular insulated wire is way too brittle for test leads. I have many devices that use test leads, so this should suffice for awhile.

As per description. . Quality is good.. be aware the insulation is very high temp soft silicone… Not a hard vinyl or pvc insulation by any means. That’s on me..I don’t know that this would be functional in a very abrasive, sharp, abusive environment. I used it the lengthen leads on a water pump which will be in a protected enclosure.. the individual wires the make up the strand are VERY fine. I bought 12 gauge and the size is correct. Again the fineness of the strands may make the less durable.. but I would tend to say it’s not and issue.. it advertised “super low impedance “ which can believe…it is tinned so it takes solder easily.. probably more for electronics in an enclosure..

Good flexible 12 gauge cable. Includes one red, and one black spool.

Very quality pure copper wire. Heavy insulated

Worked great
