Product Description

Product Introduction

This 0.3% silver lead-free solder wire not only offers excellent conductivity and ductility, but also stands out in the lead-free solder wire family and is favored for its unique rosin-containing flux. Here are two salient features:

The first good weldability: This solder wire has excellent weldability, making the welding operation easier and more efficient, suitable for a variety of complex welding tasks.

Second, no spatter: in the brazing process, it shows excellent stability, does not produce spatter, to ensure the safety of welding operations and solder joint quality.

production line

Pull out three, four, five holes containing flux in a tin wire, so that the flux is evenly distributed in the tin wire, fast welding, and improve production efficiency.

Suitable for all kinds of automatic soldering machines and manual welding with high quality requirements.
