TECHNOLOGY THAT PERFORMS

COR2 Technology
COR2 is a low density, high speed, vibration dampening material with explosive C.O.R. (coefficient of restitution) properties. Injected into PXG’s forged, hollow-body irons, the material supports an extremely efficient energy transfer, helping produce a more consistent response, incredible accuracy and an outstanding feel at impact.

World's Thinnest Face
The face is formed from ultra-thin HT1770 high-strength maraging steel that measures just 1.5mm thick, about the thickness of a penny. The weight saved by using a thin face allows more mass to be positioned in areas of the club head that help to optimize launch conditions and MOI.

Functional Face Area
Without changing the optical size of the face, PXG’s internal face perimeter cut-out design creates a 15% larger functional face area. This yields a larger trampoline for the COR2 material to react, producing faster ball speeds and significantly improving mishit performance.

Perimeter Weighting
The CNC milling process removes a significant amount of mass from the center of the hollow-body golf club. High-density, tungsten alloy weights, strategically positioned around the perimeter of the club head add mass to help increase MOI and create optimal launch conditions.
