The Callaway Great Big Bertha Tungsten Ti irons use the combination of titanium's lightweight strength and tungsten's high density to produce an iron head that is larger without making it too bulky. The tungsten is positioned low in the club to move the Center of Gravity lower to help increase initial launch angles. The deep cavity back helps move weight to the perimeter of the club for higher Moment of Inertia and forgiveness.
