Product Description

Product Introduction

Lead-free solid core solder wire Sn99Ag0.3Cu0.7

Singway produces lead-free welding wires containing 0.3% silver, which are superior in conductivity and ductility to traditional tin-copper alloys, and are 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. 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.

Why choose porous tin wire:

1. Quick welding

2. High purity is shown to reduce the variability of molten solder

3. Low residue

4. Increase productivity and reliability
