Direct-Weldable Three-Layer Insulated Copper Wire — 0.9mm Dia, 100m

High-quality direct-weldable three-layer insulated copper wire, 0.9mm diameter on a 100m length. Material: three-layer insulated copper, designed for direct welding. Key features: highly durable, resists breaking during winding, and retains a natural copper color. Welding is simple — can be soldered directly without scraping or damaging the insulation layer. Functional uses: ideal for constructing transformers, inductors, motors, speakers and potentiometers; as magnet wire it converts electrical current into magnetic fields. Common applications include producing transformers, winding coils, motors, solenoids, inductive coils, speaker coils, electromagnets and other insulated wire coils.
