There are three types of fake copper wire in the cable industry

Now there are too many types of fake copper wire and the degree of simulation is also very high, ordinary people are difficult to identify, the worst thing is that he also deceives merchants everywhere that it is all copper Oh, those ordinary businesses are only deceived, now there are the following types of fake copper wire on the market:

1) General false copper wire: copper-clad aluminum, copper-clad aluminum-magnesium alloy, copper-clad steel, copper-clad iron;

2) High imitation fake copper wire: a certain proportion of copper-clad aluminum magnesium alloy is added to the multi-stranded copper wire, and other materials are processed by electroplated copper, and the general price is much more expensive than the previous one, after all, there is real copper in it;

3) Substandard copper wire: the material is not made of oxygen-free copper brushed copper wire, the transmission performance is not good, or the number of cores is not enough;

As the saying goes, real gold is not afraid of fire, real and false SYV, RVV and other copper wire can also be used by fire to distinguish the authenticity, first pull a section of wire to expose a section of copper wire out and divide them a little sparser (that effect is better) generally with a windproof lighter burning, it will appear, the real copper wire is very resistant to high temperature, more than a minute is absolutely no problem at most will change the color a little, if it is copper-clad aluminum, copper-clad aluminum-magnesium alloy will quickly bend down, if it is copper-clad steel, The kind of copper and iron that burns and scrapes him with a knife will appear;
