Final answer:
The reactive metal with a high melting point used in manufacturing rocket nose cones is titanium.
Step-by-step explanation:
The subject of this question is Chemistry. The reactive metal with a high melting point that is used in manufacturing rocket nose cones is called titanium.
Titanium is a shiny, malleable, and ductile metal that conducts heat and electricity well. It has a variable hardness and melting temperature.
It is used for high-temperature applications such as furnace tubes, lighting tubes, and melting crucibles due to its high melting point and excellent heat resistance.
