I am not a metallurgist but seems that the era of copper and bronze came before the era of steel…that man made a repair with brass which is an alloy of the two and has a low melting point. The history of metal should have been considered and why…something to do with fires and being able to get them hot enough to melt iron hotter then what they were using to melt copper and bronze. LOL

Brass...easy to work with...yeah its soft.

Effort = A
Knowledge behind effort = F
