AP2 iron details
1020 mild carbon steel was forged to create the AP2 iron body. The AP2 looks a lot like the 735 irons but the top line is a bit thicker and the toe somewhat higher. The dual cavity design distributes weight to the edges or perimeter for forgiveness. This makes the iron more forgiving than previous Titleist creations.
The elastomer cushion boosts structural rigidity back of the impact area and cushions the dampening face vibration. This explains the Titleist AP2 iron's highly rated overall feel.
A high density tungsten-nickel box encloses the lower cavity of the titleist ap2 irons. The material keeps the weight low and significantly deep and reinforces structural rigidity while keeping vibration frequency low. Using a tungsten-nickel box was a smart choice because it reduced sole and back flange width assuring sharper performance on the greens and better shot control.
