The Cobra UFi irons are designed by integrating multiple materials; these irons feature an exclusive metal matrix face insert, patented polymer topline, high density tungsten heel-toe weighting and a steel alloy body. Combined, these advanced technologies provide the ultimate in forgiveness, along with exceptional feel. The UFi name stands for Ultimate Forgiveness irons. By employing multi-material integration and advanced head design, Cobra engineers achieved the highest MOI and lowest CG of any iron Cobra has ever produced. Together, these technologies generate the ultimate in forgiveness, distance and feel.

The Cobra UFi proprietary metal matrix face insert is a metal alloy comprised of nine different metals, which are 65% lighter than steel and 35% lighter than titanium. Nano-sized particles of Scandium (Sc) are imbedded in the metal's structure. The precision combination of the nine metals, combined with precise rolling of the material into sheets and a special heat treatment, allows the Metal Matrix material to achieve strength comparable to 431 stainless steel, while maintaining an incredibly low density. This combination of high strength and light weight make it an ideal material to free up discretionary weight, which moves the CG low, back and to the perimeter and increases MOI for ultimate forgiveness. The hardness is similar to that of a forging, which promotes a soft, solid feel at impact.

The Cobra UFi irons have a Polymer topline that weighs one-quarter of the steel it replaces, so this discretionary weight is moved from the top of the club to the heel and toe weights for a low-back CG for higher launch. The polymer topline also helps dampen vibration for improved feel. Wide-Sole Design with Tungsten Weights allows for lower CG and higher MOI in the Cobra UFi irons. The high density tungsten weights in the heel and toe shift weight low-back and to the perimeter for maximum forgiveness, high launch and superior distance. Made of aluminium, the full back cavity plate is backed with a urethane layer to dampen vibration and enhance feel. Lightweight urethane sole insert moves weight to the heel and toe, increasing MOI for maximum forgiveness. These two technologies work in concert with the Metal Matrix face insert and polymer topline to provide amazingly soft feel.
