• Gauges & Tempers: Available in various AWG/SWG standard gauges, soft (annealed) and hard tempers, with custom spooling options.

• Key Features: High electrical conductivity, smooth surface finish, excellent elongation, and reliable oxidation resistance.

Frequently Asked Questions (FAQ):

• Q: What is the difference between bare copper wire and tinned copper wire? A: Bare copper wire offers maximum electrical conductivity for standard indoor and enclosed applications, while tinned copper wire features a protective layer of tin to prevent corrosion and oxidation in high-humidity, marine, or outdoor environments.

• Q: Do you provide mill test certificates and custom spool packaging? A: Yes, every shipment includes an EN 10204 3.1 Mill Test Certificate (MTC), and we support custom spool sizes, plastic reels, and heavy-duty coil packaging per your production needs.
