Types and properites of titanium

Titanium - a light and strong metal - has changed the golf club

The larger club head, the broader sweet spot and a higher design flexibility have created 'extra distance' and 'sure direction' for your ball.

Golfers' dreams come true with titanium

Explanations and answers to your questions about titanium are shown below.

Type s and properties of titanium

From a materials science viewpoint, titanium has three types:a-titanium, ab-titanium and b-titanium. The typical a-titanium is high purity commercially pure unalloyed titanium;
ab-titanium is represented by the Ti-6Al-4V alloy; and b-titanium includes the Ti-15V-3Cr-3Sn-3Al alloy. ab-titanium and b-titanium are generally called titanium alloys. As unalloyed titanium is softer than stainless steel, golf club heads made of this material give golfers a tender feeling at the time of hitting. It is also an indispensable material when sophisticated fabrications is required. Titanium alloys, materials with other metals added to titanium, exceed stainless steel in strength and are used to manufacture cast or forged club heads. There are various titanium alloys, each with its own characteristics. By using the right titanium alloy for the right application, thus making optimum use of the properties of each material, new golf clubs with even better performance are being developed. The chemical composition of some titanium alloys used for golf club heads is shown in the table below.
