What are the differences between Solid Conductors and Stranded Conductors ?

Solid Conductors Stranded Conductors
Solid Conductors are rigid and cannot for application which require frequent bending such as the cable in a robotic arm.  They will fail due to fatigue if used in such applications Stranded conductors can be used for flexible applications
They are smaller in diameter for a given current density Larger in diameter for a given current density
Less prone to corrosion More prone to corrosion due to entry of corrosion due to capillary action
Cheaper to produce More expensive to Produce
