Sn Cu Lead Free Solder Bar

Sn Cu Lead Free Solder Bar

Introduction

Sn-Cu lead-free solder bars are commonly used in soldering metal equipments, copper tubes, copper plates, and so on. Adopting lead-free technology, it is environmentally friendly. Besides, our Sn99.3Cu0.7 solder enjoys finer grain structure and shinier surface than the conventional ones. As eutectic alloy, Sn-Cu solder rod has the melting point of227°C.




Features

1. Diameter of this Sn-Cu lead-free solder bar is more than0.2 mm.

2. It possesses a relatively low melting point.

3. High anti-oxidization makes only a little tin slag come into being.

4. Compared with conventional Sn99Cu1 alloys, this Sn99.3Cu0.7 solder shows advantages of low metal dissolution rate.

5. Optimum working temperatures ranges from260°Cto270°C.

6. Sn-Cu lead-free solder bar features good mechanical properties, strong thermal fatigue resistance, good fluidity, superior wetting characteristics and excellent soldering performance.
