Explore our top-selling enameled wires manufactured under strict quality standards for global export.
In the modern landscape of electrical design, the demand for high-efficiency, lightweight, and cost-effective conductive paths is at an all-time high. **Class 130 Enameled Round Aluminium Wire**, coated primarily with polyurethane (UEW) or polyester (PEW) resin films, represents the sweet spot of operating thermal margins (130°C) and robust physical performance for low-to-medium heat configurations.
The baseline selection of Class 130 aluminum magnet wire centers around the polymer degradation kinetics. High-purity EC (Electrical Conductor) grade aluminum is wrapped in an insulation envelope that resists thermal stress while remaining extremely flexible. The application of insulation relies on high-speed draw-and-cure tooling where layers of liquid resin are sequentially applied and cross-linked in multi-stage horizontal or vertical baking ovens.
Continuous operations up to 130°C (Class B) without dielectric degradation.
Roughly 1/3 the weight of equivalent gauge copper wire, boosting energy density in moving coils.
The Class 130 insulation coating typically utilizes modified Polyurethane (UEW) formulations. Polyurethane provides exceptional solderability without requiring prior chemical stripping of the enameled layer, significantly reducing cycle times in automated assembly lines.
For applications where direct solderability is secondary to structural moisture resistance, Polyester (PEW) insulation is utilized. This film exhibits high cut-through resistance and strong adherence properties, making it capable of surviving aggressive mechanical insertion stresses in stator winding machines.
Analyzing the shift from traditional copper coils to high-durability, lightweight aluminum configurations.
With global copper commodity price volatility, manufacturing engineers are actively switching to EC-grade aluminum. Since aluminum provides 61% of the conductivity of copper but at only 30% of the weight, it offers a dramatic reduction in the overall bill of materials (BOM) cost.
The global expansion of smart home devices, compact relay switches, and control transformers is driving demand for micro-sized Class 130 round aluminum wires. Supplier processing tolerances are pushed to limits down to wire diameters of 0.15mm.
Modern automotive and home-appliance OEMs require extensive compliance documentation. Class 130 magnet wires are strictly formulated to be RoHS and REACH compliant, using zero halogenated compounds and organic solvents that contribute to high carbon footprints.
Established as a bedrock in the Chinese electrical conductor supply ecosystem, Suzhou Daiming Electrical Materials Co., Ltd. operates a high-precision manufacturing complex built to supply demanding global markets. With customer needs at our core, we maintain full trace-back logging for every batch of raw rod input down to the shipped product spool.
Our state-of-the-art facilities span over a sprawling 258,333.33 ft² area, housing 30 highly integrated production lines running 24/7. These advanced systems deploy real-time laser diameter monitoring and high-voltage pinhole testers inline, preventing defective segments from ever leaving the plant.
How Daiming utilizes advanced automation and digital logistics to ensure cost predictability and quality output.
Using dynamic laser gauging, our wire drawing processes ensure that the aluminum core eccentricity is kept below 5%. This prevents insulation breakdown caused by thin coating points during winding mechanical stresses.
Our baking ovens feature multi-zone PID controllers, ensuring the curing temperature for the Class 130 resin remains perfectly distributed. This prevents under-curing (causing stickiness) and over-curing (causing brittleness).
Our packaging options are customized for sea and air freight. High-impact ABS spools (PT-4, PT-10, PT-25, etc.) are vacuum-sealed with silica desiccant inside custom heavy-ply corrugated cartons to prevent salt-fog corrosion.
Strict manufacturing controls yield products designed to withstand high winding tensions without breaking.
Each roll of enameled wire has undergone rigorous process and quality inspection to ensure stable paint adhesion, ensuring the insulation skin doesn't peel or flake off during high-speed tension-spooling.
The enameled wire we produce has a uniform and dense paint film, strong adhesion, scratch resistance, and excellent elasticity to support complex, tight stator packing without structural stress fractures.
We do not just ship standard spools. Our engineering department works with client specifications to match precise insulation thickness grades (Grade 1, 2, or 3) and thermal classes (from Class 130 up to Class 220).
Our high production volume across 30 lines safeguards supply chains from volatile inventory bottlenecks. We coordinate long-term blanket purchase orders for sustained manufacturing programs.
Providing low-loss materials critical for the energy transitions of global power grids, including high-efficiency industrial motors and variable-frequency domestic appliances.
Our engineers possess deep knowledge of international norms, ensuring that every product exported conforms to NEMA MW 1000, IEC 60317, or JIS C 3202 benchmarks.
