Overview
This 0.100-0.700mm Enameled Copper Wire for Voice Coil is professionally designed for high-fidelity audio and speaker equipment. We provide two mainstream insulation solutions: single polyesterimide (EI) Class 180 and composite polyesterimide over polyamide-imide (EI/AI) Class 200, perfectly matching ordinary and high-temperature working environments of speakers, earphones and car audio. The wire features stable electrical performance, firm paint film adhesion and excellent secondary softening property, ensuring clear sound quality and long-term stable operation of audio equipment.
We are a professional enameled wire factory with 20 years of manufacturing experience. This Enameled Copper Wire for Voice Coil covers a size range of 0.100mm to 0.700mm, providing two insulation options including Class 180 polyesterimide (EI) and Class 200 EI/AI composite insulation. The wire features high temperature resistance, ultra-strong paint film adhesion and excellent secondary softening performance, maintaining stable electrical and mechanical performance during long-term high-frequency vibration. It is widely applicable to HiFi speakers, car audio systems and Bluetooth earphone speakers. All products have complete certification qualifications. We support sample testing, OEM customization and large-scale mass production with flexible MOQ and 15-day delivery cycle. Welcome to contact us for technical parameters and samples!
Core Product Advantages
1. High Temperature Resistance: Dual temperature grades of Class 180 and Class 200 optional, resisting high heat generated by high-frequency vibration of voice coils, not easy to age or deform.
2. Super Strong Paint Adhesion: Uniform and smooth paint film with strong bonding force, no peeling or cracking during high-speed winding and long-term vibration.
3. Excellent Secondary Softening Performance: Good thermal softening characteristic, convenient for voice coil shaping and fixing, improving production yield for audio manufacturers.
4. Ultra-stable Overall Performance: Consistent wire diameter and stable conductivity, effectively avoiding sound distortion, noise and unstable acoustic output.
5. Professional Audio-grade Matching: Suitable for full-range audio equipment from mini earphone speakers, HiFi speakers to vehicle-mounted car audio systems.
