"Designed for maximum corrosion resistance in the harshest environments, this 2/0 Tinned Stranded Copper wire is engineered for long-term performance. Featuring a high-purity copper core coated in a protective layer of tin, it provides the perfect balance of conductivity and chemical durability, making it the premier choice for marine, industrial, and high-moisture grounding systems."
The 2/0 Tinned conductor is the heavy-duty standard for environments where standard bare copper would fail. The tin coating acts as a permanent barrier against oxidation, salt air, and corrosive soil, ensuring your grounding system maintains its integrity for decades.
Superior Corrosion Resistance: The tin layer prevents the "greening" (oxidation) common in salt-air and high-humidity environments.
Ease of Termination: Tinned copper is significantly easier to solder and provides a cleaner, more reliable connection in mechanical lugs by preventing galvanic corrosion.
Soft-Drawn (Annealed): Despite the protective coating, the wire remains flexible for routing through marine hulls or industrial conduit.
7-Strand Construction: A rugged, high-strength design that offers excellent mechanical durability for demanding commercial and utility applications.

2/0 Tinned Copper is the industry standard for high-corrosion environments. It is most frequently used in marine grounding systems, coastal electrical services, and industrial facilities like chemical plants or water treatment centers where salt air or corrosive fumes would degrade standard bare copper.
The primary benefit is longevity. Standard bare copper will oxidize and turn green or black when exposed to moisture or salt. Tinned copper features a protective layer that stops this oxidation process, ensuring the wire maintains its low resistance and high conductivity for the life of the installation.
No. It is still a soft-drawn (annealed) conductor, so it remains flexible. In fact, many electricians prefer tinned copper because it is easier to solder and creates a more stable connection with mechanical lugs in wet environments.
Yes. Tinned copper is excellent for direct burial, especially in acidic or salty soils that are aggressive toward standard copper. It is often used in grounding rings for coastal substations.
The OD of our 2/0 Tinned Bare Copper Wire is approximately 0.414 inches.
