Introducing Nickel Chromoly
A new material with so much additional ball speed, our engineers switched their focus to feel and stopping power.
35% stronger than our original Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface
Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot Metal irons are as enjoyable and controllable as they are long.
 
 
TECHNICAL DETAILS
Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
Seamless Cup Face: Thinned areas revolving 360 degrees around the perimeter increase rebound area for maximum ball speed across the entire face
CORTECH Design: Optimized face thickness distribution to maximize COR AREA
Variable Sole Thickness: Increase overall face flex area for add CORAREA
Acoustic Sound Ribs: Precisely dial in specific vibration patterns for a solid, explosive impact sound
Beveled Trailing Edge: Aggressive relief on the trailing edge for reduced turf drag
V-Chassis: Engineered via Mizuno's Harmonic Impact Technology, the V-Chassis allows the top line to be thinner without sacrificing feel and sound.
4335 Nickel Chromoly: 4335 Nickel Chromoly is 20% stronger, allowing for an 8% reduction in face thickness, resulting in higher ball speeds.
White Satin Brush Finish: A modern elegant, yet durable non-glare finish
