Product Description



  • Hand: Right¬†
  • Flex: Regular, Stiff
  • Shaft: Steel

With the JPX 900 Hot Metal Iron we set out to Engineer the Longest Hottest - broad appeal iron we've ever made. By utilizing new materials and new methods of construction we were able to produce an iron with an unmatched level of ball speed.

Chromoly 4140M:

  • 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.

Power Frame:

  • 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.

Simply incredible irons
Clearly the best irons I have ever played. Great improvement over my JPX800's. The technology is great. These feel like forged irons and have a massive sweet spot. I cannot imagine how the next generation could be any better.

Long, forgiving, and.....rusty?
The clubs swing great, have solid contact (not quite the forged feel but still great for a cast club). They are incredibly long, and fairly forgiving on miss hits. I've pushed and pulled a few but no crazy hooks or slices.

My only issue with these clubs is that they rust. Like second time using them there was rust on them. Small marks on the face surprised me after the first couple rounds. I clean my clubs after each shot, and have them in individual head covers but they are SOFT! Not to mention the rust, yes rust. The 360 cup design hides grass and rust as well so youll need a good set of pipe cleaners get fish that out....

The Best Mizuno irons I've owned so far.
I have been purchasing Mizuno irons ever since I owned one. I have the MX900, MX25, MX300, MPH4, JPX-EZ-Forged and now the JPX900 Hot Metal. I played with the JPX900HM for the first time last Saturday The feel is buttery and the distance is a club longer than the JPX EZ-Forged. Roughs are not a problem. The ball goes straight to where you aim it. It is the best Mizuno iron I have owned and played so far.
