Mizuno JPX 925 Hot Metal Black men's irons, steel

Maximum Distance. Outstanding Forgiveness. Premium Black Design. The Mizuno JPX 925 Hot Metal Black irons redefine the performance of an already industry-leading franchise, combining powerful new technologies with Mizuno's world-renowned feel. For the first time in the Hot Metal series, Mizuno introduces multi-material construction — pairing high-strength Nickel Chromoly with strategically placed tungsten weighting — to deliver explosive ball speeds, higher launch, and steeper landing angles that hold greens with confidence. The striking Black Ion finish gives the set a premium matte look while reducing glare in bright sunlight.

These irons are ideally suited to mid-to-high handicap golfers who demand long, stable ball flight, maximum forgiveness on off-centre strikes, and the sleek aesthetic of a modern all-black design.

Key Features

• CORTECH Design with Contour Ellipse Face: Completely re-engineered multi-thickness face profile — up to 30% thinner than the previous generation — enhances centre ball speed and ensures consistent distance across the entire face.
• Multi-Material Construction with Tungsten Weighting: Tungsten is positioned low in the 4–7 irons, creating a lower sweet spot and a higher launch angle, producing a steeper, green-holding descent angle for more precise approach shots.
• Nickel Chromoly 4140M: High strength-to-weight alloy enables a stronger, faster face with exceptional malleability — allowing for a bendable hosel for precision fitting adjustments.
• Seamless Cup Face: One-piece cup face geometry with thinned areas revolving 360° around the perimeter increases the rebound area for maximum ball speed across the whole face.
• Balanced Stability Frame: Balanced weighting improves control and forgiveness while producing a tour-preferred vibration signature and impact sound.
• Variable Sole Thickness: Fine-tuned head geometry increases overall face flex for added CORAREA and enhanced energy transfer at impact.
• Harmonic Impact Technology: Precisely engineered head geometry fine-tunes feel and feedback, delivering a solid yet responsive sensation on every strike.
• Acoustic Sound Ribs: Strategically placed ribs precisely dial in vibration patterns for a solid, explosive impact sound that inspires confidence.
• Black Ion Plating Finish: Premium matte-black surface treatment that delivers a stylish, tour-inspired look while reducing glare on the course.
• Maximum Forgiveness: High MOI design maintains ball speed and directional stability even on off-centre contact, making every round more consistent.
