| No | Project | Features |
|---|---|---|
| 1 | Appearance | The surface should be bright with an even color, free from tin shedding, black spots, cracks, burrs, yellowing, tin tumors, etc. |
| 2 | Diameter | The allowable deviation is within ±0.01mm. |
| 3 | Tin Plating Thickness | It is divided into thin plating (1.5-2.5mm), medium plating (2.5-4.0mm), and thick plating (above 4mm). |
| 4 | Elongation | ≥15%, or customized according to customer requirements. |
| 5 | Electrical Conductivity | It is divided into low conductivity (16-18%), medium conductivity (18-22%), and high conductivity (above 24%). |
| 6 | Repeated Bending | Can withstand ≥4 times of repeated bending. |
| 7 | Tensile Strength | ≥245KG/mm². |
| 8 | Solderability | At 250±2℃, lead-free tin dipping for 2±0.5 seconds, with a new tin adhesion rate of ≥95%. |
| 9 | Aging Test | After baking at 200±5℃ for 1 hour, there should be no yellowing or darkening. |
| 10 | Continuity | After three cycles of testing with hydrochloric acid and sodium polysulfide solution, there should be no copper exposure or black spots. |
| 11 | Bonding Strength | After wrapping more than 6 circles and immersing in saturated sodium polysulfide for testing, there should be no cracks or darkening. |

Product Introduction：
Tinned copper-clad steel wire is a product made by taking low-carbon steel as the core wire, annealing and softening it into soft steel wire, then electroplating a copper layer chemically, and finally hot-dipping it in lead-free tin-based alloy. The production cost is relatively low, making it an ideal substitute for tinned copper wire.
