Is solid wire better than stranded wire?


Quick Answer

Choosing between stranded and solid wire depends on the amount of movement required in each wire. Stranded wire is more flexible than solid wire, which makes it a better choice in situations where a wire needs to move around frequently.

Solid wire consists of a single strand of wire. It is usually used to construct electronic circuit boards on a breadboard. In contrast, stranded wire is made of several small pieces of wire bundled into one group. According to Advancement International, stranded wires are commonly used in "applications where vibration and occasional movement of the wire could cause breakage of a stiffer solid wire or rigid stranded conductors."

Stranded wires also have larger diameters than solid wires as a result of the air trapped between the strands. Although stranded wires are more flexible than solid wires, they are also more expensive. Therefore, when selecting between stranded wire and single wire, factor in the costs associated with using one wire type over another. The advantage of using a solid wire over a stranded wire is that it is more compact and cost effective. However, stranded wire is only available in small sizes, and it is more prone to breaking in strenuous situations.
