Tinned Copper vs Bare Copper

Bare copper is fairly resistant to corrosion, but when it is used in wet environments or places with high humidity, it can quickly become damaged.  When bare copper is operating at temperatures that exceed 100 degrees Celsius, it may start to degrade. This kind of damage can result in a loss of performance. If cost is of any concern, then bare copper is less expensive than its tinned counterpart.

By coating bare copper with a metal alloy, like tin, you can strengthen the copper’s natural properties, which will give it a longer shelf life. Also, tinned copper is easier to connect because tin is a primary component in solder. Tinned copper is better equipped to resist humidity, high temperatures and wet environments.

When considering bare copper or tinned copper wiring, the environment and cost should heavily dictate which type of wire you choose. To learn more about bare copper or tinned copper wire, contact your account manager at Distributor Wire & Cable today at 888.439.2947.
