Zinc, magnesium, cobalt, cadmium, Mercury, Zirconium, antimony and bismuth = HCP (APF=74%).
Gamma-iron, aluminium, Calcium, copper, lead, Gold, Platinum, silver and nickel = FCC (APF=68%).
Alpha-iron, delta-iron, tungsten, Sodium, chromium, Manganese and molybdenum = BCC (APF=52%).

@Shivaraj Ankada.
Hexagonal close packing volume occupied is 74%, and no. of atoms per unit cell is 6 which is not same as for FCC.
