Product Outline
Below is a detailed breakdown of the product, organized into H3 subheadings to explain its properties, applications, and advantages.
1. What is Polyurethane Enamel?
Polyurethane enamel is a type of insulating varnish applied to magnet wires like aluminum and copper wires. Its primary role is to provide a reliable insulating layer that resists heat, moisture, and mechanical stress. Unlike other types of enamel, polyurethane enamel is specifically designed for direct soldering, making it a preferred choice for applications where fast assembly is critical.
2. Why Choose Aluminum Wire Over Copper Wire?
While copper wire has traditionally been the go-to material for magnet wire, aluminum wire offers distinct advantages:
- Lightweight: Aluminum is lighter, reducing the overall weight of electrical systems.
- Cost-Effective: It is more affordable than copper, making it ideal for budget-conscious applications.
- Solderability: When coated with polyurethane enamel, aluminum achieves excellent direct soldering properties.
3. How Does Polyurethane Enamel Improve Solderability?
The solderability of this wire lies in its polyurethane enamel coating, which melts effortlessly during the soldering process. This eliminates the need for time-consuming processes like removing the enamel coating manually. Additionally, it ensures:
- Stronger Connections: The enamel melts evenly, forming robust soldered joints.
- Simplified Production: Reduces production time in industries like motors and transformers.
4. Applications of Solderable Polyurethane Enameled Aluminum Wire
This wire finds applications in a wide range of industries due to its exceptional properties:

- Relays and Solenoids: Ensures durability and resistance to wear.
5. Thermal Class 155 and Its Importance
The thermal class 155 rating signifies that this wire can withstand temperatures up to 155°C without degrading. This makes it suitable for applications demanding high levels of heat resistance, such as:
- Industrial Motors: Operates under continuous high-temperature conditions.
- High-Speed Winding Applications: Maintains performance even during rapid winding processes.
6. The Role of Insulation in Enameled Wire
Insulation is critical in preventing electrical short circuits and ensuring efficient energy transfer. The polyurethane insulation in these wires provides:
- High Dielectric Strength: Essential for preventing voltage leaks.
- Moisture Resistance: Protects the wire from environmental damage.
- Chemical Resistance: Ensures durability in harsh conditions.
7. Benefits of Using Solderable Polyurethane Enameled Aluminum Wire
This wire offers numerous advantages over traditional wires:
- Ease of Use: Direct soldering simplifies assembly processes.
- Durability: Resistant to abrasion and chemicals.
- Cost Savings: Aluminum is more cost-effective than copper.
8. What is the Recommended Wire Size Range?
The wire size ranges from 0.008 mm to 0.50 mm, accommodating a variety of applications. Smaller sizes are ideal for precision devices like voice coils, while larger sizes work well in motors and transformers.
9. How is the Wire Manufactured?
The manufacturing process involves several critical steps:
- Wire Drawing: Aluminum is stretched into precise diameters.
- Application of Polyurethane Enamel: The wire is coated with an even layer of insulating enamel.
- Curing Process: The enamel is cured to ensure durability and direct solderability.
10. Comparing Polyurethane Enamel to Polyester Enamel
While polyurethane enamel is prized for its direct soldering properties, polyester enamel offers better mechanical strength. For applications requiring direct solderability, polyurethane is the superior choice. However, for heavy-duty applications, polyester may be preferred.
