When I was exploring the nether with ropes, I found some problems: ropes are easily burned or destroyed by ghasts, even plastic ropes that cannot be burned can be blown up by ghast, which brings trouble to the exploration.
So I thought of adding some stronger and non combustible metal ropes, such as bronze or steel ropes. However, these metal ropes require wirecutters to be properly recycled, but when they are cut, all the ropes below will be automatically recycled and only the durability of cutting the first rope will be consumed. This also means that it is more suitable as a more permanent setup (I know scaffolding should be more suitable, but scaffolding is not suitable for situations that require downward extension). In addition, it can also be used as decoration for suspension bridges.
Tensile strengths of metals and metal alloys,
Steel has a tensile strength of between 400 and 2000MPa, depending on the composition, bronze has ~450MPa and gold ~120MPa for comparison, based on the weight of most metals, the only ropes that would feasibly work without snapping would be: steels and steel alloys, titanium alloys, cobalt nickel alloys, possibly aluminium?
Thinking about it, aluminum probably wouldn’t be good in the Nether either, much lower melting point, even before reaching it its tensile strength would reduce dramatically.
Perhaps it could be like a metal bars, made of bronze/steel/titanium/tungstensteel/adamantium, although this may not be very realistic, it is more convenient.
