Class 200 Aluminum Enameled Wire Polyester-Imide Base With Polyamide-Imide Overcoat, High Thermal Resistance Magnet Wire for Transformers

🔧 Frequently Asked Questions (FAQ)

❓ Q1: What is the difference between aluminum enameled wire and copper enameled wire?

✅ A: Aluminum wire is lighter and more cost-effective than copper, but has lower electrical conductivity (about 61% IACS). It’s ideal for applications where weight reduction or cost savings are priorities, such as in certain motors, transformers, or coils. Copper offers better conductivity and mechanical strength.

❓ Q2: What thermal class does your aluminum enameled wire support?

✅ A: Our standard polyester-imide insulated aluminum round wire meets Thermal Class 180 (Class H), suitable for continuous operation at up to 180°C. We also offer other insulation systems (e.g., polyamide-imide for Class 200) upon request.

❓ Q3: Is your aluminum magnet wire compliant with international standards?

✅ A: Yes. Our products comply with IEC 60317, NEMA MW-35-C, and GB/T 4074 standards. Test reports and certificates (e.g., RoHS, REACH) are available upon request.

❓ Q4: Can aluminum enameled wire replace copper wire directly?

✅ A: Not always. Due to lower conductivity, you may need a larger cross-sectional area of aluminum wire to carry the same current. We recommend consulting our engineering team for design adaptation to ensure performance and safety.

❓ Q5: What diameters and tolerances do you offer?

✅ A: We supply round aluminum enameled wire from 0.1 mm to 3.0 mm bare diameter, with tight tolerance control (e.g., ±0.005 mm for fine gauges). Custom sizes are available.

❓ Q6: How is the wire packaged?

✅ A: Standard packaging: Spools (plastic or wooden) with moisture-proof film and desiccant, net weight typically 5–25 kg/spool. Custom packaging (e.g., large drums for automated winding) is supported.

❓ Q7: Do you provide samples?

✅ A: Yes! We offer free or paid samples (depending on specification) for quality evaluation. Lead time: 3–7 days.

❓ Q8: What’s your MOQ?

✅ A: MOQ starts from 50 kg for standard specs. Lower quantities may be accepted for trial orders.

❓ Q9: How do you ensure consistent quality?

✅ A: We implement strict in-process controls:

• Online diameter monitoring

• Pinhole testing (per IEC 60317)

• Thermal shock & scrape resistance tests

• Full traceability from raw material to finished spool

❓ Q10: What industries use your aluminum enameled wire?

✅ A: Common applications include:

• Small/medium electric motors (e.g., HVAC fans, pumps)

• Transformers and inductors

• Automotive auxiliary motors

• Consumer electronics coils
