CHINGCUNG® Special Enameled Wire Expert

Premium Grade 1 – Polyurethane Enameled Aluminum Wire Lightweight & Cost-Effective

QAL-1/155 Enameled Aluminum Round Wire
Polyurethane Base | Thermal Class 155 (Class F) | Grade 1 Insulation Film | Conductor Dia. 0.15 – 2.00 mm

Lightweight alternative to copper wire — ideal for transformers, inductors, motors & coils where weight reduction and cost efficiency matter.

Why QAL-1/155 Grade 1 Aluminum?

Grade 1 provides minimum insulation film thickness, allowing smaller outer diameters and higher winding density. Aluminum conductor offers significant weight savings (approx. 1/3 of copper) and cost benefits. Combined with polyurethane insulation, QAL-1/155 delivers direct solderability, thermal endurance up to 155°C, and excellent windability — perfect for large transformers, ballasts, and lightweight coil designs.

Technical Specifications (Grade 1 Focus)

Dimensional Characteristics — Grade 1 (Minimum Film Increase)

QAL-1/155 Grade 1 offers thinner insulation build compared to Grade 2, maximizing aluminum fill factor for larger winding windows. Below table shows typical conductor diameters with min. film thickness & max. outer diameter for Grade 1 (Grade 2 shown for reference).

Note: Grade 1 provides approx. 15-25% thinner outer diameter vs Grade 2, enabling more turns per winding window. Aluminum conductor offers ~1/3 weight of copper with comparable conductivity per weight. Data based on IEC 60317-15 standard. For diameters above 2.00mm, please contact our engineers.

Product Overview & Core Features

CHINGCUNG QAL-1/155 enameled aluminum wire is designed for applications where weight reduction and cost efficiency are primary concerns without compromising thermal reliability. The high-purity aluminum conductor, combined with a uniform polyurethane Grade 1 insulation, delivers excellent electrical performance for transformers, inductors, and large coil windings. The lightweight nature (approximately 30% of copper density) significantly reduces overall equipment weight, making it ideal for aerospace, automotive, and large-scale power distribution.

✦ Key engineering advantages: Direct solderability (with proper flux) eliminates pre-stripping, reducing assembly time. The polyurethane varnish provides outstanding moisture resistance and flexibility. QAL-1/155 Grade 1 minimizes insulation build-up, allowing compact winding designs while maintaining dielectric strength. Aluminum's natural corrosion resistance further enhances long-term reliability in humid environments.

✦ Quality commitment: Each batch undergoes pinhole testing, continuity verification, and breakdown voltage checks. Our production lines are optimized for aluminum wire processing to ensure consistent elongation and surface quality. Full traceability from aluminum rod to finished spool is provided.

Frequently Asked Questions (QAL-1/155 Grade 1 Aluminum)

• Q1: What are the main benefits of aluminum enameled wire vs copper?
  A: Aluminum offers approximately 1/3 the weight of copper and lower material cost, making it ideal for large transformers, ballasts, and applications where weight reduction is critical. However, for the same conductivity, larger cross-section is required.
• Q2: Is QAL-1/155 directly solderable like copper wire?
  A: The polyurethane insulation is solderable (decomposes at ~390°C), but aluminum requires proper flux to remove oxide layer. We recommend specialized aluminum solder/flux for reliable connections.
• Q3: What diameter range does CHINGCUNG offer for QAL-1/155?
  A: Standard range is 0.15mm – 2.00mm for Grade 1. Larger diameters up to 4.00mm and rectangular aluminum wires are available upon request.
• Q4: Can QAL-1/155 be used to replace copper wire in existing designs?
  A: Yes, but the aluminum conductor diameter needs to be larger (approx. 1.25x copper diameter) to achieve equivalent ampacity. Our engineering team can provide cross-reference guidance.
• Q5: Does the aluminum wire meet international standards?
  A: Yes, QAL-1/155 complies with IEC 60317-15, GB/T 23312.5, and NEMA MW 25-C. Full test reports available.
