A tinned wire is a copper wire coated with a thin layer of tin, offering added protection against corrosion. Commonly used in marine, outdoor, and high-moisture environments, tinned wire is prized for its durability and longer lifespan. Unlike bare copper, it resists oxidation, making it ideal for wiring exposed to saltwater or humidity. Electricians and marine professionals prefer tinned wire for its superior conductivity and ease of soldering. If you’re working in harsh conditions or need reliable long-term performance, tinned wire is a smart choice. It’s a simple upgrade that ensures your wiring lasts significantly longer.
