A: While aluminum has lower conductivity, our precisely engineered wire gauges compensate for this, achieving comparable electrical performance in many applications with significant weight and cost benefits. -
Q: What specific UL standards does the insulation comply with?
A: Our enamel meets UL 1441 for Magnet Wire Insulation and can be certified to UL File No. E346819 upon request. -
Q: Can I get custom diameters or spool sizes?
A: Yes, we offer diameters from 0.1mm to 5.0mm and customizable spooling configurations for OEM requirements. -
Q: How does temperature rating affect my application?
A: Class 155 (F) suits most industrial motors, while Class 180 (H) is recommended for high-heat environments like automotive underhood components. -
Q: Do you provide material test reports?
A> Comprehensive test reports including continuity, breakdown voltage, and thermal shock tests accompany every shipment. -
Q: What packaging options ensure transit safety?
A> We use moisture-resistant cartons, wooden spools, or steel drums with anti-corrosion paper for overseas shipments. -
Q: Are there minimum order quantities?
A> MOQs are flexible based on wire gauge - contact us for specific requirements. -
