--> The Big Bertha Fusion Irons are the most untraditional traditional-looking irons you will ever play. Fusion s Three-Piece Technology utilizes multiple materials in clubhead construction to move mass where it does the most good . Three-Piece Technology: Lightweight titanium is used in Fusion Irons to make the rest of the club heavier. The lightweight titanium face is 35% lighter than a comparable steel face, allowing more mass to be moved to the club perimeter for faster ball speed , greater feel , a larger sweet spot , forgiveness and increased effective hitting area . To form the heavy cradle, Callaway Golf metallurgists created an entirely new metal alloy called Tunite, which is a base of tungsten and nickel. A small amount of silicon softens the mixture and ferro-chromium is added for a polished look. The Tunite cradle allows 77% of the mass to be positioned around the extreme perimeter of the iron for ultra-high MOI (Moment of Inertia) and a low, deep CG (center of gravity). With no twisting or turning , balls fly straighter off the club. The TPU SenSert is a thermoplastic urethane layer that sits snugly behind the clubface. It is turned to the titanium clubface to reduce vibration at impact , improve feel and deliver crisp, responsive acoustics .
