With the JPX 900 Hot Metal Iron, Mizuno set out to Engineer the Longest, Hottest - widely appealing iron ever made. By utilizing new materials and new methods of construction, Mizuno was able to produce an iron with an unmatched level of ball speed and accuracy.
15% stronger material than 17-4 pH Stainless steel provides the added strength for our hottest face ever
Ultra-thin face combined with our re-engineered CORTECH multi-thickness design provides superior initial ball speed for maximum distance
More mass is pushed to the extreme perimeter of the club head for industry leading MOI
POWER FRAME geometry is a result of our Harmonic Impact Technology.The rigid POWER FRAME provided an extremely solid impact sound while allowing maximum face rebound.
UNITIZED CUP FACE GEOMETRY:
Through complex development techniques we were able to achieve Unitized Cup Face Geometry, delivering a massive COR AREA.
Unitized Cup Face Geometry also provides more discretionary weight than welded cup face designs, thus allowing for a deeper CG and greater forgiveness
