Whenever an item needs to be made light weight and high strength, titanium is always considered for its manufacture. Most titanium alloys possess the same strength as common grades of stainless steel, but are 40% less dense (the weight per volume area). Titanium therefore is commonly chosen for the manufacture of aircraft parts and medical equipment where strength at a lightweight is important. In a wood head, even though a driver head, for example, will always be designed to weigh between 190g – 205g, the lower density of titanium allows the head to be made much larger in size and still possess the same strength than if a steel alloy were used.
Steel's higher density means the maximum size for a wood head is about 310-320cc before the head would exceed the weight requirement for a normal club. Titanium driver heads can be made larger than 500cc and still weigh 190g – 200g because of the lower density. In addition, titanium possesses a higher strength to modulus ratio than steel. This means it is possible to manufacture the face of a wood head from titanium and achieve a better spring face performance (high COR) than with all but extremely high strength steel alloys. What about Titanium and it's alloys are so important? Metallurgy has developed hundreds of different tests to compare the mechanical properties of metals to each other.
In golf, for the manufacture of club heads, there are four key metal mechanical properties in the production of titanium wood heads. A titanium wood head is constructed of 3 to 4 pieces welded together. Each different piece (face, crown, skirt, sole) has different stress put on it and is looked to perform different duties, therefore each piece can be made of differing titanium alloys. The mechanical properties needed to produce a high COR face are not the same as the crown. The key properties of Titanium for wood head design are: Density The ratio of the mass of a substance to its volume, expressed, for example, in units of grams per cubic centimeter or pounds per cubic foot. The density of a pure substance varies little from sample to sample and is often considered a characteristic property of the substance. Density often is taken as an indication of how 'heavy' a substance is.
Iron is denser than cork, since a given volume of iron is more massive (and weighs more) than the same volume of cork. It is often said that iron is 'heavier' than cork, although a large volume of cork obviously can be more massive and thus be heavier (i.e., weigh more) than a small volume of iron. This is a property that is very important in all parts of the club head as we like as light, low density, a club head as possible. Tensile Strength The measure of a material's ability to resist rupture. In other words, how much force is required to fracture the material. Tensile strength is also defined in PSI or KSI.
This too is also important for the manufacture of the face and body parts of a wood head. Hardness A comparative scale measurement of the ability of a material to resist surface deformation.
In other words, how much does one material resist permanent denting of its surface. Hip Hop Samples. While there are several scales of comparison for hardness, the one most commonly used in conjunction with golf club head design is the Rockwell Scale of Hardness. Hardness is important for all parts of a wood head, though more important for the face. Elongation A comparison of the ductility of different materials. In other words, how easy is one material to stretch than another before it breaks such that the higher the number the easier to stretch the material before breaking. Elongation is defined as a per-cent of the dimension of the test piece, such that a higher per-cent value represents greater ductility of the material. Elongation is an important property for both the face and the body parts of the wood head because it will offer an indication of the ability of the face or top crown to flex before permanent damage could occur.
Titanium Material Chemistry Titanium is a metallic element which in its pure form, possesses very low strength and would be quite unsuitable for the moderate to high stress requirements of the parts of a wood head. While some grades of pure titanium (referred to as commercially pure (CP grades) are used in the manufacture of the crown, sole and skirt parts of a wood head, most of the Titanium materials known by clubmakers are titanium alloys. An alloy is a metal that is a combination of different chemical elements mixed with the base metal for the purpose of intentionally creating different but very specific mechanical properties. Thus, titanium metals known to clubmakers by names such as 6-4, 10-2-3, SP700, etc are all titanium alloys. Titanium Alloys One of the most confusing parts of evaluating the quality of a titanium wood head concerns the various grades and alloys used in their manufacture. It is very common for 2 or 3 different grades or alloys of titanium to be used in the manufacture of the various parts of the head. The names or numerical designations of the various titanium alloys are commonly used in the marketing of the heads to try to associate levels of quality with one specific Ti alloy over another.
