There are many different titanium alloys (materials added to the raw titanium) to change both the weight and strengths requirements. With driver heads reaching the maximum volume of 460 cubic centimeters, the most common alloy is 6/4 Titanium, by which 90% of the material is titanium, 6% is aluminum and 4% is vanadium. There are many other alloys or grades of titanium (sometimes called Beta Titanium) such as 15-3-3-3, SP700, 10-2-3, etc. available to the club designer. If the higher grade of titanium is used, then it is normally for the face material only and not the entire head.

The United States Golf Association (USGA) and the Royal and Ancient Golf Club of St. Andrews (R&A) – the two governing bodies in golf – established rules for how fast a ball can come off of the club face of a driver. Most manufacturers make drivers that go to this limit without exceeding it, so there really is no advantage of one material over another. Typically, smaller drivers (under 400cc) would utilize the higher cost beta titanium to increase how fast the ball
