1, carbon materials: mainly cheap golf clubs
used to make carbon rod body. General is in graphite join in, or join carbon ceramic components and glass fiber, etc, make more the light more strong; 2, titanium alloy: generally used in the manufacture of DRIVER stem head. The density of titanium is fairly small,
about 60% of the iron. But has high strength, high temperature heat treatment can be easily, welding, forging characteristics. Titanium alloy is refers to the pure titanium join in other metals, and to improve his characteristics. 4. 42 iron 7. 86 6-4 titanium: it's in the pure titanium to 6%, 4%
