What is the crystalline structure of brass alloy_________________?
Show answer Hide answer
Answer: A. F.C.C.
Explanation
Brass is a substitutional solid solution alloy consisting primarily of copper and zinc. Its atoms arrange themselves in a face-centered cubic lattice crystal structure. This atomic arrangement contributes significantly to the good ductility and malleability of brass. Face-centered cubic structures feature atoms located at each corner and the center of cube faces. Copper naturally crystallizes in a face-centered cubic lattice configuration at room temperature. Adding zinc atoms retains this primary crystal lattice while altering mechanical properties.
Manufacturers use brass for plumbing fittings, musical instruments, and decorative hardware. The FCC crystal structure allows brass to be easily shaped through cold working processes. Engineering components made of brass offer excellent corrosion resistance in moist environments. Body-centered cubic structures are typical of iron at lower temperatures and certain steels. Hexagonal close-packed structures are found in metals like titanium, magnesium, and zinc. Orthorhombic lattices do not characterize standard binary brass alloy crystal formations.
