Made from high-quality copper, it delivers excellent conductivity, heat resistance, and durability, making it perfect for motors, transformers, speakers, and scientific experiments. With a tensile strength of 250 MPa and glowing user reviews, it’s the go-to wire for professionals and hobbyists alike. ## Description Product Description 0.3mm 20m Enamelled Copper Wire 1.The 0.3mm*20M Enameled Wire Is Copper Wire Covered With A Thin Insulating Layer. Scrape Off the Isolation Layer before Use and Use Copper Wire Instead of Wire and Cable. 2.It has high temperature resistance,good hardness and is not easy to break. 3.The Copper Wire is not fading and rust, good flexibility and durability. 4.It is widely used and can be used in physical science experiments,small generators,motors,transformer, induction, engine, speaker, hard disk drive protagonist, electromagnetic machine and other applications that require tight coil insulation wires.etc. Feature the copper wire covered with a thin insulating layer. Scrape off the isolation layer before use The 0.3mm enameled wire is made of high-quality copper material with high conductivity. It has high temperature resistance,good hardness and is not easy to break. Review: Running traces - I bought this wire to run and remake traces on PCBs. It works perfectly. The enamel melts when you want it to and insulates well when you don’t. It’s done a great job and I reckon that reel of it will last ages. Review: Nice 1 :-) - Perfect for what i needed to repair. ## Features - Surface with Insulating Layer:The Copper Wire Covered With A Thin Insulating Layer. the copper strands conduct electricity and the insulating layer protects the windings from short circuits, when soldering, please scrape off the insulating coating on the soldered part, it is very safe. - High-quality Copper Wire: The 0.3mm Enameled Wire Is Made of High-quality Copper Material With High Conductivity. - Not Easy to Break:LIt Has High Temperature Resistance,good Hardness and Is Not Easy to Break. - Widely Used: it Can Be Used in Physical Science Experiments,small Generators,motors,etc.you can use to make small fabrications requiring fine copper wire or to solder relatively small model circuits, which is very useful. - SHOP WITH CONFIDENCE: To Provide You With the Highest Quality Service, If You Have Any Question, Please Contact Us.We Will Provide After-sales Service . ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09SHF76CY | | Best Sellers Rank | 9,246 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 10 in Copper Wire | | Brand | DONGKER | | Brand Name | DONGKER | | Colour | black | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 177 Reviews | | Finish Type | Polished | | Finish type | Polished | | Grade Rating | Commercial | | Item Diameter | 0.3 Millimetres | | Item Form | Spool | | Item Shape | Round | | Item Thickness | 0.3 Millimetres | | Manufacturer | DONGKER | | Material | Copper | | Model Number | 1 | | Number of Items | 1 | | Part Number | 1 | | Recommended Uses For Product | Physical science experiments, small generators, motors, coils, transformers, inductance wires, maintenance copper wires, speaker magnetic coils | | Recommended uses for product | Physical science experiments, small generators, motors, coils, transformers, inductance wires, maintenance copper wires, speaker magnetic coils Recommended uses for product Physical science experiments, small generators, motors, coils, transformers, inductance wires, maintenance copper wires, speaker magnetic coils See more | | Tensile Strength | 250 Megapascals | | UPC | 774590131535 | | Unit Count | 1.0 count | ## Product Details - **Brand:** DONGKER - **Colour:** black - **Finish type:** Polished - **Material:** Copper ## Images ![Enamelled Copper Wire, 0.3mm x 40m Magnet Winding Wire - Image 1](https://m.media-amazon.com/images/I/51VWDvVhJQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Running traces *by I***S on 5 October 2025* I bought this wire to run and remake traces on PCBs.
