Mizuno are breaking new ground with their latest JPX900 irons by adding three sets with different materials used in each.
Building on the success of the JPX 850 Forged – one of the brand’s most popular models ever – Mizuno now have a JPX iron for every type of golfer.
We had traditionally associated the JPX brand with the game-improvement market but the success of the JPX850 forged proved that even the best players in the world are keen to take advantage of the additional performance benefits.
And with vastly improved aesthetics across the board, the JPX900 range could even tempt loyal MP users to switch over.
The JPX900 Series comprises three new models – JPX900 Tour, JPX900 Forged and JPX900 Hot Metal, each with very distinctive performance attributes, made possible by their unique base materials.
The larger of the three models is the JPX 900 Hot Metal which could be seen as a replacement for the JPX 850 (non-forged model).

It features Mizuno’s newest material Chomoly 4140M which the brand says combines offensive ball speeds with the adjustability benefits of a forged iron.
The Chromoly 4140M has allowed Mizuno to create their thinnest ever cup face for added distance, but also remains soft and bendable in the hosel for precise lie angle adjustments.

“It’s great for a designer when a new material like Chromoly comes into play,” says Chis Voshall, Mizuno club designer.
“It opens up a world of new avenues for us. We’ve been looking for a material that gives a little more pop from the face, but without the hardness that stops us bending the neck for custom- fitting. Chromoly opened that door.”
The JPX900 Forged, replacing the JPX850 Forged, is the second generation of Mizuno’s Forged irons to use Boron-infused steel, which allows a soft-feeling forged iron to produce higher ball speeds.
