1 the difference between bright copper wire and red copper

Electrical conductivity. 1 The difference between bright copper wire and red copper lies in its conductivity. The copper content of red copper is very high, so the conductivity of red copper is much stronger than that of photoelectric copper. Both of them are widely used to manufacture products that require good conductivity, such as wires, cables, brushes, copper corrosion for EDM, and magnetic instruments and meters that need to prevent magnetic interference, such as compasses and aviation instruments.
