While the Zinc Core is an Alloy, there has never been a documented case where there is a lamination of the zinc core. I suspect this is because the other metals in the alloy are such tiny amounts.
Zinc ALLOY 190: COMPOSITION (% by Weight) Lead = 0.005 max; Iron = 0.010 max; Cadmium = 0.005 max; Copper = 0.7 to 0.9; Zinc = Balance.
