Product Description

Product Introduction

Lead-free solid core solder wire Sn99.3Cu0.7

This kind of lead-free solid core solder wire does not contain rosin, uses high purity tin metal raw materials, automatic extrusion,unique oxidation resistance, full tin filling solder bright, suitable for all kinds of high quality requirements of automatic soldering machine soldering operations.

Singway produces lead-free welding wires that are superior in conductivity and ductility to traditional tin-copper alloys, making them high-end welding wires. During brazing, it provides excellent solder joint continuity, does not sputter, and leaves little residue. This welding wire is suitable for computer board, automobile industry, intelligent control and other fields, whether it is automatic welding machine or manual welding operation, it can meet the high quality requirements.

In addition to this, we provide first-class customer service and support to ensure that you get the best possible experience during the welding process. Our welding wires emit very little smoke and do not contain harmful volatile gases, ensuring the safety and health of users. It is the ideal choice for reliable and efficient welding in industries where quality is highest. With Singway, you'll get excellent welding performance and excellent customer support.

Porous tin wire: A tin wire with multiple truly independent holes containing flux that are stretched from a single wire distributes the flux evenly throughout the wire, demonstrating a fast-wetting material with excellent solder joints.

Why choose porous tin wire:

1. Eliminate the risk of lack of flux

2. The probability is less than 120 times that of competitive products

3. Improve wetting performance

4. Flux closer to the welding environment
