Rosin Core Solder and Its Uses

The most common method of joining wires cables and electrical conducting materials together is using soldering methods. If you are joining wire or metals that operate under extreme conditions of temperature where fluctuations vary between cool to very hot, then most likely rosin core solder would be used.

Rosin-core solder is a metal alloy with a pitch-like organic compound substances which melt easily and adheres well to copper and other metals, creating a strong bond that conducts electricity. Rosin-core solder consists of a metal tube that surrounds a thin core of rosin. When you apply heat to solder, the metal and rosin melt together. The solder and rosin flow onto an electrical connection, typically copper wires twisted together.

Rosin core solder has the excellent feature of great joins that to a relative degree have heat resistance, and lasting qualities against premature aging of soldered joints, thus keeping a long lasting and durable electrical join against the elements.

Rosin core solder is used for electronics as well as in construction and manufacturing and comes in a variety of thicknesses. It is used, across the electronics industry, in digital communications and technology, the military, for heavy-duty transformer cables, high-rise building cable runs and even in the refrigeration industry because it keeps a strong join against the vibration from refrigerator motors.
