Tinned Copper Cables

Our tinned copper cable has the copper conductor that is encased with a thin layer of tin. This layer coated with tin is helpful for the protection against corrosion, particularly in conditions that have exposure to humidity, moisture or salt. Coated with thin layer, the cable protects itself against the oxidation, which improves the durability and achieves the extension of longevity in harsh conditions. High conductivity of copper can be maintained with the help of the tin coating. Applications that require flexibility and resistance to corrosion frequently needs tinner copper cables.

What a tinned copper wire differs from bare copper wire?

The major differences between tinned copper wire and bare copper wire lie in a tin coating on the copper conductors in tinned copper wire. However, a bare copper wire has no tinned layer protection cover. Some differences are shown below:

Corrosion-resistant: Tinned copper cable is protected by the tin coating against corrosion, particularly in moist and humid environments (such as marine & outdoor use). The tin layer protects the copper from oxidation, which a longer lifespan can be achieved. On the contrary, bare copper wire has no protective tin coating, making the bare copper more susceptible to corrosion in moist or humid conditions that degrade the performance as time goes by.
Durable: With highly protective tin layer, tinned copper wire is more durable in extreme conditions, which enables long-term uses in conditions that have high exposure to corrosion. Bare copper built in bare copper cables is not as protective as in high-demanding environments while they are still durable in dry and monitored conditions.
Solder: With the coating of tin layer, soldering can be easier achieved, which enables stronger and cleaner links. It is possible to achieve the soldering of bare copper, but more preparation is required and a smooth connection may not occur in comparison with tinner copper cable.
Price: Because of the additional tinning process, tinned copper cable tends to be costly. However, the cost is s usually justified by the extension of longevity in some devices. Compared to tinner copper wire, bare copper cable are often less expensive, but more frequent replacement or maintenance in extreme conditions may be needed.

Why tin is used to copper wires?

Because of the nature of corrosion resistance, tin is commonly applied in copper wires. Here are the benefits of tin:

Corrosion Protection: Oxidation, which results in corrosion, may easily occur to copper in marine, outdoor or industrial uses where moisture, humidity or salt are frequently contacted. Here tin coating works well as a barrier to protect the straightforward exposure of copper to the components, which greatly decrease the hazard of oxidation and corrosion.
Extended Lifespan: Through the protection of the copper wires against environmental conditions that enables quicker degradation of bare copper, the longevity of tinned copper cable can be extended.
Enhanced Solderability: Due to the readier bonding of the tin coating, tinned copper cables can be easily soldered, with which more reliable and cleaner electrical links are ensured.
Conductivity Maintaining: Tin has no negative impact on the excellent electrical conductivity of the copper even it offers protection, which enables effective performance of the wire in different devices.

What are typical applications of tinned copper cable?

Marine Navigation & Communication System: Tinned copper cables have widespread applications in marine vessels to function navigation lighting, GPS systems, radar, and radio communication applications. And durable and resistance to corrosion are required for these devices because of the continuous exposure to saltwater & moisture.
Solar Panel PV System: Solar panels are applied to connect inverters and batteries by using tinner copper wires that carry the strong capability to ensure lengthened exposure to UV rays, rainy day and other harsh weather conditions. This can protect the cable from corrosion, which is a perfect choice for outdoor solar setups.
Auto Battery Cable & Alternator Use: In vehicle electrical systems that require battery connections and alternator wiring, tinned copper cables are widely employed. The applications are subject to humidity, heavy oils and salt, which require heavily on the tinner copper cable for the achievement of reliable links.
Outdoor LED Lighting: For outdoor landscape lighting or street lighting, tinned copper cables are often used due to their ability to resist corrosion from rain, snow, and fluctuating temperatures. This ensures that the lighting system remains functional over long periods with minimal maintenance.
Recreational Vehicle & Electrical System: Tinned copper cables are widely applied for recreational vehicles for their onboard solar electricity systems, the connections of battery, and exterior electronic elements. The corrosion resistance capability of the copper wire from outdoor uses and temperature fluctuations plays essential roles in ensuring the reliable electricity division in RV.

What are the benefits of tinned copper wire?

Some major benefits are listed below:

a. Corrosion-resistant: Great protection against corrosion is generated by using the tin layer coated on copper cables, particularly in conditions that have high exposure to humidity, oil and salt. This enables the copper cable to use in marine, auto and outdoor uses where bare copper cables may degrade swiftly because of the oxidation.

b. Enhanced Longevity: Tinner copper cable usually has lengthened longevity in extreme conditions because of the resistance to corrosion. With this durability, the need for maintenance and replacements is decreased, which is time-efficient and money-consuming over time.

c. Intensified Solderability: The soldering of tinned copper cable can be easily achieved with the use of tin coating because the bonding of tin is more efficiently created than bare copper wire. This generates cleaner, more durable and more stable solder joints, which plays an essential role in devices that frequent soldering is required.

d. Strong Electrical Conductivity: The tin layer on the copper cable has no great impact on the excellent electrical conductivity although it has strong resistance to corrosion. This enables the high electrical performance of tinner copper wire. What’s more, it functions durably.

e. Flexible & Durable Capability: The routing and installation of tinner copper cable will be easier to achieve in confined spaces or along complicated elements, though it has high flexibility. Along with the improved durability, the flexibility allows it appropriate for devices where the frequent motions or exposure to vibration are required.

f. Against Harsh Conditions: The copper wire is protected by the tin coating against harsh environmental conditions like high-temperature, chemical substance, and UV ray exposure. This enables tinner copper cable to be applied in devices like solar systems, offshore areas and industrial devices, where extreme environments over long periods can be achieved.

What does the corrosion resistance of tinned copper cable achieve?

a. Barrier-Tin Coating: Working as a barrier between the copper conductor and the condition, the tin coating avoids direct exposure of the copper wire to humidity, oxygen and corrosive components, which is especially efficient in conditions where a high presence of salt is required. The conditions include marine environment, or some places where humidity and moisture matter.

b. Avoiding Oxidation: Oxidation can be caused by the exposure to air and water in copper with no protection, which results in the creation of copper oxidation. This decreases the conductivity of the copper cable and the performance is compromised. However, oxidation can be avoided with the use of tin layer since tin has fewer reactions with oxygen than copper.

c. Saltwater & Chemicals Resistance: Powerful resistance is provided by using tin coating to be against corrosive chemicals, such as saltwater. The tin layer provides protection of copper against swift degradation especially saltwater that can enhance corrosion. The degradation may be generated due to the exposure to seawater. This works the same in industrial devices, where the cable might be contacted with oils, acids or other slated substances.

d. Prevention in High-Moist Conditions: Bare copper can be corroded faster with high moisture, particularly in high-moisture conditions. And tinned copper cables are typically applied in such environment since tin layer protects moisture from reaching the copper. Therefore, the risk of corrosion from water can be reduced.
