SPEED INJECTED™ Technology
Mizuno's MP-20 MMC Irons feature Grain Flow Forged HD construction, where each iron is crafted from 1025E carbon steel single billet. The construction concentrates metallic grains within the impact area to boost performance and consistency while bringing forth the signature feel. The head geometry is fine-tuned to deliver an ideal impact feel.
Apart from carbon steel chassis, Mizuno MP-20 MMC irons also feature tungsten and titanium positioned in the clubhead. Titanium enhances MOI while delivering a solid sound and feel at impact. Tungsten weighting offers incremental enhancements in the MOI and higher launch.
A softer feel on impact is experienced thanks to a layer of copper underneath the nickel-chrome finish.
