Question

Copper is generally a polymorphous material with body centered cubic (BCC) lattice structure.

(a) True

(b) False

The question was posed to me in quiz.

The above asked question is from Copper Alloys in division Foundry Introduction & Materials of Casting-Forming-Welding II

Answer 1

The correct choice is (b) False

For explanation I would say: Copper is a non-polymorphous material with face centered cubic (FCC) structure. The FCC structure is the only reason for ductility in the copper material. Pure copper is generally reddish in color, and addition of zinc produces the yellow color of the copper and nickel produces the silver color of the same.
