What is "copper rate"?

The thickness of each copper wire contained inside is above 1.3mm (purchased with parallel wire (thin wire) if it is less than 1.3mm).

Items without tin plating (tin), enamel, etc. (in some cases purchased with parallel wire (thin wire)).

The parts that are equivalent to the coating are metals (such as iron, lead, metal mesh, etc.) or hard resins. The parts that are difficult to peel off are sometimes not purchased (the purpose is to remove the internal copper wire and reuse it, so easy peeling is important). Do not purchase Aziro wires (marine wires, marine wires) that are difficult to strip.
