The NANOALLOY Era: Breaking Down the New Mizuno JPX ONE

The NANOALLOY Era: Breaking Down the New Mizuno JPX ONE

Mizuno has often been viewed as a purist’s brand - synonymous with the feel of a grain-flow forged iron. But their metalwood division has been quietly building momentum for decades. With the release of the JPX ONE family they are introducing a material change that fundamentally alters how a driver face handles energy.

For the gear heads and the players looking for tangible gains, here is the technical breakdown of the new line-up.

The Driver: A Material Shift

The headline story here is the face. For the first time, Mizuno (in collaboration with Toray) is utilizing NANOALLOY™ technology.

Most modern drivers rely on titanium or carbon composites. NANOALLOY™ is different. It uses microscopic polymer dispersion to create a face structure that dynamically alters its elasticity at impact.

  • The Benefit: It stores and releases more energy than traditional materials, generating higher ball speeds across a wider surface area.

  • The CORTECH Factor: They’ve paired this new material with a re-engineered face that is up to 0.35mm thinner than previous generations.

  • The Result: The "high-speed rebound zone" (CORAREA) is over 15% larger than the ST-MAX.

Two Distinct Driver Profiles

Mizuno has simplified the choice into two clear chassis options, both featuring adjustable weighting and the Quick Switch hosel system:

1. JPX ONE

  • Profile: Larger footprint.

  • Flight: Higher stability with a straighter ball flight.

  • Best For: Players seeking maximum forgiveness and consistency.

2. JPX ONE SELECT

  • Profile: Compact, tour-preferred shape.

  • Flight: Neutral-to-fade bias.

  • Best For: Players who want workability and a traditional look at address.

Fairway Woods: The Re-Engineered Chamber

The JPX ONE Fairways focus on turf interaction and maximizing energy transfer from the bottom of the swing arc.

  • CORTECH Chamber: The internal gap between the sole and chamber wall has been varied to increase face flexion specifically towards the toe and heel. This maintains ball speed on off-center strikes.

  • Speed Bevel Sole: A new sole design refines turf interaction for cleaner strikes from varied lies.

  • Composite Crown: A wrap-around carbon crown lowers the center of gravity (CG), promoting high launch and low spin.

  • Lofts Available: 15° to 24°.

Hybrids: Iron-Like Precision

The hybrids are designed as true iron replacements, utilizing a Waffle Crown structure to free up weight, which engineers have pushed lower and deeper into the head.

  • Face Tech: A uniform-thickness 1.8mm MAS1C face ensures speed consistency.

  • Lofts Available:19°, 22°, 25°, and 28°.
