High Temperature Enameled Copper Wire 0.64mm QZY-2-180
High Temperature Enameled Copper Wire 0.64mm QZY-2-180 is a copper conductor covered with enamel insulation for compact electrical winding. This listed version has a 0.64mm conductor diameter, a 20m length, and QZY-2-180 insulation designation. It is intended for buyers who need a defined wire size and insulation class for coil winding, repair, prototyping, or small-batch electrical assembly.
What Is Enameled Copper Wire?
Enameled copper wire, also called magnet wire, is a copper conductor with a thin insulating enamel coating. The copper core provides the current path, while the coating separates adjacent turns when the wire is wound into a coil. Because the insulation is applied directly to the conductor, the finished winding can occupy less space than a wire using a thick outer jacket.
The QZY-2-180 designation identifies the listed insulation construction and temperature class stated for this product. The designation should be read together with the actual technical datasheet, because insulation thickness, solderability, dielectric performance, and applicable test requirements can vary by manufacturer and supply specification.
Key Product Parameters
| Parameter | Listed value or description |
|---|---|
| Product type | Enameled copper magnet wire |
| Conductor material | Copper |
| Conductor diameter | 0.64mm |
| Length | 20m |
| Insulation designation | QZY-2-180 |
| Primary use | Magnetic coil winding and electrical repair |
| Supply form | Wire length as listed; confirm packaging before ordering |
The 0.64mm size is the main dimensional reference for winding-space calculations and electrical comparison. The 20m length is useful for repair work, samples, prototypes, and smaller coil projects. For production requirements, confirm the delivered length, tolerance, spool or coil format, outer diameter, and packing method with the supplier before purchase.
Properties and Performance Factors
The performance of an enameled copper wire depends on both the copper conductor and the enamel system. Copper offers good electrical conductivity and can be formed around a bobbin, core, or former. The enamel layer provides turn-to-turn insulation and must remain intact during winding, bending, routing, and termination.
- Winding insulation: the enamel helps separate neighboring turns and reduces the risk of turn-to-turn contact when the wire is used within its rated conditions.
- Dimensional consistency: a stable 0.64mm conductor size helps engineers estimate winding fill, resistance, and connection fit.
- Thermal selection: the 180 class designation is a selection reference, not a guarantee that every finished assembly can operate continuously at 180 C. The complete system must also account for current, cooling, winding geometry, and surrounding materials.
- Mechanical handling: excessive tension, sharp edges, unsuitable tooling, or repeated scraping can damage enamel and reduce insulation reliability.
- Termination: the enamel must be removed by a compatible method before soldering, crimping, welding, or other electrical connection unless the construction is specifically designed for direct soldering.
Typical Applications
This 0.64mm QZY-2-180 wire can be considered for applications that require an insulated copper winding conductor in a controlled size. The final choice should be checked against the original winding design and the equipment manufacturer’s requirements.
- Transformer and inductor coil winding
- Small motor and generator winding repair
- Electromagnet and magnetic coil construction
- Prototype electrical assemblies and educational models
- Replacement winding wire for maintenance projects
- Short-run repair work where a 20m length is practical
For a repair, compare the new wire with the removed conductor by diameter, insulation class, winding space, connection method, and operating temperature. A visually similar wire can still produce a different winding resistance or insulation result if its size or coating system is different.
Installation and Handling Guidance
Keep the wire clean, dry, and protected from abrasion before use. During winding, guide the conductor smoothly and avoid sudden tension changes. The bobbin, core, winding tool, and wire path should have no burrs or sharp edges that can cut the enamel.
After winding, inspect the surface for scratches, flattened sections, exposed copper, loose turns, and damage near the lead ends. Remove the enamel only from the intended termination area, then clean the conductor and verify that the connection is mechanically secure. If the assembly is used in a high-temperature or high-voltage environment, perform the project-specific insulation and electrical checks before release.
Standards and Quality Verification
QZY-2-180 is the insulation designation listed for this product. It should not be treated as a blanket statement of compliance with every regional or equipment standard. Depending on the project, buyers may need to confirm relevant IEC, NEMA, JIS, GB, or customer-specific requirements with the supplier.
A practical incoming inspection can include conductor diameter measurement, visual enamel inspection, length or weight verification, continuity checks, resistance measurement, insulation pinhole review, and dielectric withstand testing where required by the design. For repeat orders, record the approved diameter, insulation designation, test method, acceptance limits, lot information, and packaging condition. This creates a repeatable quality record without assuming tests that are not stated in the product listing.
Comparison with Other Magnet Wire Options
| Selection factor | 0.64mm QZY-2-180 wire | Other wire options |
|---|---|---|
| Conductor size | Defined 0.64mm reference | May be thinner or thicker, changing winding fill and resistance |
| Insulation reference | QZY-2-180 designation as listed | May use another thermal class or enamel system |
| Project scale | 20m length suits samples and shorter jobs | Longer spools may be better for production winding |
| Termination | Requires confirmation of enamel removal method | Some specialized wires support different termination processes |
The right comparison is application-based rather than keyword-based. Select the wire that meets the required conductor area, winding space, thermal duty, dielectric requirement, mechanical handling, and available quantity. A thicker wire is not automatically better, and a higher temperature designation does not replace correct current and insulation design.
Buyer Checklist
- Confirm that the required conductor diameter is 0.64mm and check the permitted tolerance.
- Confirm that QZY-2-180 is the required insulation designation for the application.
- Check whether 20m is enough for the winding, lead ends, testing, and possible rework.
- Confirm the required color, packaging, outer diameter, and delivery condition if they affect assembly.
- Define the enamel removal and termination process before production or repair.
- Request a datasheet, sample, inspection record, or compatibility confirmation when the application is safety-critical.
FAQ
Q: What is the main specification of this wire?
The listed conductor diameter is 0.64mm, the length is 20m, and the insulation designation is QZY-2-180.
Q: Is it suitable for coil winding?
Yes. It is listed for magnetic coil winding and can be evaluated for transformer, inductor, motor, electromagnet, and repair applications when the project requirements match.
Q: Does 180 mean the finished coil can always run at 180 C?
No. The designation is an insulation selection reference. Actual operating temperature also depends on current, cooling, winding construction, surrounding materials, and the complete equipment design.
Q: Can the wire be soldered directly?
Do not assume direct solderability from the listing alone. Confirm the enamel system and use an approved stripping, thermal, chemical, or mechanical termination method.
Q: Is 20m enough for production?
It may suit samples, maintenance, prototypes, and small jobs. Production winding should be checked against the required winding length, waste allowance, and repeat-order packaging.
Q: What information should be included in an inquiry?
Include the 0.64mm size, QZY-2-180 designation, required length, application, quantity, packaging preference, delivery location, and any drawing or inspection requirement.
