"WebIn a bcc arrangement, a unit cell contains (8 corner atoms × ⅛) + (1 center atom × 1) = 2 atoms. The packing is more efficient (68%) than simple cubic and the structure is a common one for alkali metals and early transition metals. The primary phase of low-carbon or mild steel and most cast irons at room temperature is ferromagnetic α-Fe. " - Iron bcc
