Still worried about wire oxidation?

Having worked in electronics factory procurement for over a decade, wire oxidation has always been our biggest headache. Especially in the humid weather of southern China, ordinary copper wire would begin to develop a verdigris after just three months in storage. It wasn't until I used Yipu's Stranded Tinned Copper Wire that this problem was truly resolved.

Why is tinned copper wire a must-have for humid environments?

Last year during the rainy season, we nearly had to return a batch of equipment due to oxidation. After replacing it with Yipu's Stranded Tinned Copper Wire, the joints remained as bright as new after six months in the same environment. The experienced technicians in the workshop now say that this wire is worry-free to use.

Will the tin coating affect electrical conductivity?

I was initially concerned about this as well. Tests have shown that the conductivity of Yipu's Stranded Tinned Copper Wire is only about 2% lower than that of pure copper wire, well within the acceptable range. Their tinning process is also very uniform, preventing areas of excessive thickness that affect conductivity.

Will frequent bending cause breakage?

The automated equipment on our assembly line bends wires thousands of times a day. Ordinary copper wire breaks after just a month, but Yipu's Stranded Tinned Copper Wire lasts over six months, and when I disassemble it, it's still intact. They truly use a sophisticated annealing process.

Will soldering be difficult?

On the contrary, it's much easier to solder than ordinary copper wire! The tin coating on Yipu's Stranded Tinned Copper Wire has a low melting point, making soldering easier. Our soldering yield has increased by five points, and the solder joints are stronger and fuller.

Is it more expensive than ordinary copper wire?

The math makes it clear: the saved rework costs, reduced scrap, and extended lifespan make Yipu's Stranded Tinned Copper Wire a much better value. We've now switched to this wire for all our critical processes. If you're still worried about oxidation on your circuits, you should try Yipu's Stranded Tinned Copper Wire. Our factory now exclusively uses this material for new projects, and its consistent quality is reassuring. Samples are shipped quickly, and the technical specifications are detailed on their official website.
