Sourcing tinned copper wire that actually performs in production can be a headache — inconsistent diameters or flaky coatings kill yields and waste time. For your reference, Our wire starts with high-purity copper and a uniform tin layer that stays bright and smooth, so you get reliable solder joints and fewer rejects on the line.

Tinned Copper Wire

Whether you're winding resistors, capping capacitors, or assembling fuses and transformers, this wire handles heat without discoloring or dissolving. It's built for wave soldering and reflow processes, and honestly, the weldability is solid — no fussing with brittle connections.

Tinned Copper Wire Applications

Diameters run from 0.3mm to 3mm, with tolerances tight at ±0.01mm to ±0.02mm. Elongation hits at least 20% in soft temper, and tensile strength ranges from 13 to 28 kg/mm² depending on hardness. Just keep in mind that the coating thickness sits at ±2μm, so if you need a heavier tin layer for extreme corrosion environments, this might not be the best fit.

Tinned Copper Wire Specifications

Every spool meets GB/T, JIS, and ASTM standard, backed by ISO9001, RoHS, SGS, and Reach certifications. Temperature resistance goes up to 200°C, and resistivity stays below 0.0190 Ω·mm²/m for smaller gauges. Packaging comes in PP reels, vacuum packs, or iron trays — whatever keeps your line running smoothly.

Frequently Asked Questions

What are the minimum order quantity (MOQ) and typical lead time for custom sizes?

Our MOQ for custom-sized tinned copper wire is usually 100 kg per size, but we can negotiate for smaller trial orders. Lead time is around 15-20 days from order confirmation, depending on the quantity and coating thickness.

Can you provide ISO9001, RoHS, SGS, or Reach certificates with the shipment?

Yes, we include ISO9001, RoHS, SGS, and Reach certificates with every shipment. Just let us know which ones you need, and we'll attach them to the packing list.

How do you ensure the tin coating thickness stays within ±2μm across the diameter range of 0.3mm to 3mm?

We use automated electroplating lines with real-time thickness monitoring to keep the coating within ±2μm. Each spool is spot-checked with a micrometer and X-ray gauge before packing.

What packaging options do you have for sensitive applications like fuse elements?

For fuse elements, we recommend vacuum packing or PVC shaft spools to prevent oxidation and physical damage. We also offer PP reels and iron trays; just specify your preferred method when ordering.

Is the elongation and tensile strength guaranteed for both soft and semi-hard tempers on every batch?

Absolutely — each batch is tested for elongation (soft ≥20%, semi-hard 13-24%) and tensile strength (soft 13-23 kg/mm², semi-hard 20-28 kg/mm²). We provide a test report with every shipment.
