For over 50 years since our establishment in 1970, Shandong Huilong Electrical Material Co., Ltd. has specialized in manufacturing premium electrical components from our 20,000+ sqm facility in Dezhou, China. Our enamelled round aluminum wire represents decades of refinement, specifically engineered for electric motor repair shops seeking reliable winding solutions. With annual exports exceeding $100 million to global markets including North America, Europe, and Southeast Asia, we combine scale with precision engineering to deliver consistent quality that keeps industrial motors running at peak performance.
This product addresses the core challenges faced by motor repair technicians: providing a cost-efficient alternative to copper that maintains excellent conductivity while reducing overall motor weight. Manufactured by our team of 100+ skilled professionals, each batch undergoes stringent quality checks throughout production. The result is a wire that ensures optimal slot fill and thermal management in rewound motors – critical factors that extend equipment lifespan and reduce callback repairs.
Technical Specifications & Performance Advantages:
- Superior Insulation Integrity: Triple-layer enamel coating provides exceptional dielectric strength (typically >8kV) and resistance to chemicals commonly found in industrial environments
- Thermal Endurance: Standard Class 155 rating (180°C optional) withstands thermal cycling stresses in demanding applications
- Mechanical Durability: Optimized elasticity and scrape resistance (minimum 150 strokes) for smooth winding operations
- Conductivity: 61% IACS minimum conductivity aluminum alloy maintains efficiency while offering 50% weight reduction versus copper equivalents

| Diameter Tolerance | ±0.005mm | ±0.002mm available |
| Break Elongation | ≥15% | Up to 25% |
| Packaging Weight | 5-20kg spools | Bulk coils up to 500kg |
| Surface Finish | Smooth enamel | Adhesive coatings available |
The unique concentric ovality control in our drawing process ensures uniform wire geometry that prevents winding gaps and hot spots. When repairing AC/DC motors, generators, or transformers, technicians benefit from:
- Reduced winding time due to excellent bendability and memory retention
- Compatibility with all standard impregnation varnishes and dipping processes
- Lower inventory costs through interchangeable use across multiple motor types
- Minimal waste from breakage during high-speed winding operations
Backed by ISO9001 and IATF16949 certified manufacturing systems, our wire ships globally from Qingdao, Shanghai, and Ningbo ports with documented material traceability. Serving 15+ international markets including automotive suppliers and industrial service centers, we maintain strict batch-to-batch consistency – a critical factor when repairing mission-critical motors. The 100+ quality control checks from raw material to finished spool ensure your repair shop receives wire that meets original equipment specifications while providing better value than copper alternatives.
Partner with a manufacturer that understands motor repair economics: our aluminum wire delivers up to 30% material cost savings without compromising on breakdown voltage or thermal performance. Contact our technical team today for sample requests or custom diameter configurations – let our five decades of wire expertise become your competitive advantage in motor servicing.
Frequently Asked Questions:
-
Q: Can this wire replace copper in all motor repair applications?
A: While suitable for most applications, we recommend consulting our engineers for high-frequency or extreme temperature environments above 200°C where material selection requires specific evaluation. -
Q: What makes your aluminum wire suitable for inverter-duty motors?
A: Our proprietary enamel formulation provides enhanced resistance to partial discharge effects, with tested voltage endurance exceeding IEEE 1776 requirements for VFD applications. -
Q: Do you provide documentation for material traceability?
A: Yes, all shipments include material certifications with heat number traceability back to aluminum ingot sources. -
Q: What winding precautions should be taken with aluminum vs copper?
A: Use tension settings 20-30% lower than copper equivalents and ensure termination lugs are specifically rated for aluminum conductors to prevent cold creep issues. -
Q: How does thermal expansion affect performance?
A: Our alloy formulation minimizes differential expansion with insulation layers, maintaining bond integrity across operating temperature ranges. -
Q: What minimum order quantities apply?
A: Standard diameters ship from 50kg with no MOQ for custom diameters (lead times apply). -
Q: Can I get sample spools for testing?
A: Yes, we provide 1-5kg samples with full technical documentation for evaluation purposes. -
Q: How does your pricing compare to copper alternatives?
A: Typically 25-40% lower per kilogram while maintaining equivalent electrical performance in most motor repair scenarios.
