HEAD Liquidmetal tennis racquets revolutionize racquet design with a completely new material. Regular racquet materials often deform on impact, stealing energy away from the ball. HEAD Liquidmetal is composed with a liquid atomic structure, preventing it from deforming under pressure. This allows it to return all energy it receives from your swing and on impact back into the ball, making sure none of your effort is wasted! Players can expect to see power increases of up to 29%! HEAD Liquidmetal is also 2 1/2 times stronger than titanium, allowing it to remain strong under pressure. In addition to the strength of the material, the corrugated shape of the HEAD Liquidmetal locations increases surface rigidity and stiffness. This in turn increases the torsional stability of the racquet head, keeping it from twisting on off center shots. HEAD Liquidmetal racquets contain Liquidmetal applied to the racquet head in four strategic locations. The result is no energy loss, more power, more stability, and a significantly larger sweetspot. HEAD Liquidmetal tennis racquets are also accompanied by various technologies such as NoShox and IDS (Integrated String Dampener).
