Created with durability in mind, SMAI's Ductile Cast Iron Kettlebells are crafted from a single molded unit.

SMAI Kettlebells are manufactured from Ductile cast iron which is essentially a cast alloy containing Carbon content (3.6% Graphite which is Crystalline Carbon) which makes it superior to standard Cast Iron (Gray Cast iron) giving it superior moldability and ability to withstand a high level of stress and deformation before breaking.

The molding process eliminates casting marks or rough edges on the outer surface and handles, making them smooth and comfortable, even for double-hand use with smaller hands. With color-coded handles, weight denominations are quickly identified. Finished with a powder-coated surface, the Cast Iron Kettlebells ensure excellent grip.
