Aluminum cables! Quality - less than 10mm² - Only suitable for CarHifi when mini-conditioning in the car

Unfortunately, this cable contains a very high Aluanteil which sets down the quality of a 20mm² a niedriegeren section (ca10mm²)!
That is only partially suitable for CarHifi, eg for smaller systems that do not require a lot of electricity.
A star there but for processing!
I've uploaded images comparison, as you can see the difference between a proper copper cable and this article.
The build quality I've tried to capture.

A proper copper cable cost per meter ca 6 (this set here has 6m, 6x6 = 36 plus fuse 5-10, terminals 5 ...)
This product consists of pure copper cable -> ACR HKAB-81 Cable set Power + RCA 20mm Dear few uro pay more, but you then also really good quality.
Because this cable contains aluminum, would have a larger cross section embarrassed to get the quality of a pure copper 20mm² cable.
Is related to the fact that aluminum has a lower current density than copper: it flows through the same amount of copper as more current with the same amount of aluminum in the same time.
That's like having a very thin straw and a viscous Gertänk -> you have to suck it like a madman because something comes -> thicker straw -> easier to drink with less "Saugaufwand" :)

You also have to remember that aluminum is oxidized faster -> transition resistances at the terminals. Also available in aluminum heavy pressure after also -> terminals can loosen over time ..

Generally speaking, all these cable sets, which you get for around 20 have (also on eBay), a very high Aluanteil the cable!

Have sent the item back and get my money back! Thanks for the smooth handling!
