Titleist TSi2
Introducing the New TSi2 Driver ATI 425 AEROSPACE TITANIUM FACE Accurately tuned for speed at every point of contact, TSi driver faces are constructed from ATI 425 Aerospace Titanium, a unique material that delivers superior strength, elasticity and durability versus the conventional titanium alloys used in golf. The exceptional ductility of ATI 425 (30 percent higher than 6-4 Titanium) allowed engineers to produce Titleist’s fastest driver face, while maintaining the durability properties required for consistent maximum performance. “ATI 425 is an amazing alloy that leads to a lot of performance benefits,” said Dan Stone, Senior Vice President, Titleist Golf Club R&D. “It’s incredibly strong and maintains elongation under high stress. It let us optimize the thickness of the entire face to a degree that was never possible before and generate our highest ball speeds ever at points all over the face – not just heel and toe but also high and low. This is not an easy material to ob
