Question

I have question

Why is a helmet made from bronze more useful than a helmet made from copper or tin?

Answer 1

Answer:

the reason is that bronze being an alloy of copper tin and zinc is much stronger than only copper or zinc

Answer 2

Answer:

Bronze is harder than copper as a result of alloying that metal with tin or other metals. Bronze is also more fusible (i.e., more readily melted) and is hence easier to cast. It is also harder than pure iron and far more resistant to corrosion.
