The Wires Are Red Copper. Okay? Or Brass?

The wire is the same whether it is made of red copper or brass. Because the resistance of copper is the same, there is no difference in conductivity. However, the brass wire is relatively hard if it is a soft core of brass and brittle, so usually brass are used in the switch and such as the physical, such as the switch screws, contact position, wire head fork, etc.. And red copper is also called red copper, its plasticity is relatively high, and more flexible, multiple folding will not be easy to disconnect, so usually the wire is used in red copper.
