Acid flux has strong cleaning action, but leaves corrosive residue that washes away with water. This solder is electrically conductive.

The flux leaves minimal residue so there's no need for cleanup. All of this solder is electrically conductive.

The flux leaves minimal residue so there's no cleanup. The solder keeps its strength in applications where vibration and frequent and extreme temperature changes occur, such as in water lines and refrigeration equipment.

The five flux cores in this solder allow fast soldering that uses solder efficiently and reduces the heat to your joint. The flux it’s filled with leaves minimal residue so there’s no cleanup. This solder is electrically conductive, making it good for electronics and electrical applications.

The five flux cores allow fast soldering that uses less solder and transmits less heat to the joint. Rosin flux is quick acting with strong cleaning action but leaves residue that requires flux remover. Since this solder is electrically conductive, it’s good for electronics and electrical applications.

Use this solder for general purpose applications. It does not have a flux core, so you can choose the flux that works best for your application.

Electrically conductive, this solder is best for electronics and electronics applications. It does not have a flux core, so you can choose the flux that works best for your application.
