WebBCC crystals have 48 slip systems but only 5 are independent (5 is the minimum requirement for ductility). However, the 5 independent slip systems may not be activated at all temperatures, so some BCC metals are ductile while others are brittle. The 48 BCC slip systems are {110}<111>, {112}<111>, and {123}<111> in order of ease of activation.
