On the complexities of rope/tension:
It's going to be made of steel wire, and it'll likely have man made cores, the actual type of steel and the build of the rope and how it's laid depends on many things: the corrosion resistance required, whether the rope is required to be wound over a pulley or drum under load, the radius of such pulley or drum, the safe working load required, normal operating temperature range required, ...
There is no "perfect" steel for wire rope, because (for example) when you change the composition of the steel for more flexibility, you'll get less strength, it's always the best compromise for the application. It's just "a length of rope" but building wire rope is as complicated as building a structure.
This document gives a good overview of the complexities of wire rope:
