Golf club material:

1, Carbon materials: mainly used in the production of carbon rod body. It is generally added to the graphite in the ceramic composition, or adding carbon and glass fiber, etc., so that more light and more robust;

2, Titanium alloy: generally used to manufacture DRIVER rod head. The density of titanium is very small, about 60% of iron. But with high strength, easy high temperature treatment, welding, forging and other characteristics. Titanium alloy refers to the pure titanium in addition to other metals, in order to improve his characteristics. Four 42 iron 7. Titanium 866--4: in pure titanium added 6% aluminum, 4% alum, used for casting rod head beta titanium (usually meaning) - in the pure titanium join 15% alum, 3% chromium, aluminum 3%, 3% nickel, forging rod head; SP700 with the 15-3-3-3 beta titanium performance similar, belong to high quality golf clubs matter beta titanium

3, Tungsten: Tungsten density is quite large, about 4.5 times of titanium, used for rod head counterweight. (tungsten 19.5)

4, Mild Neo soft iron. In cast irons, in stainless steel adding% carbon to become very hard; forging, join between 0.1 ~ 0.3% carbon, become soft;

5, Stainless Neo stainless steel ----sus630 added a 17% Cr and 4% nickel) - used for casting, earlier for Ping famous back empty type cast irons, and now it is widely applicable to iron and wood. ----sus304 (adding 18% Cr and 8% Ni), it is softer than sus630.

6, Other materials: beryllium copper (1%~~2.5% +: beryllium copper, stainless steel) than weighs about 6-7%, used for the manufacture of wedges. Aluminum alloy: (Al + 4%-6% lead and 2%-3% magnesium), lighter, more robust and easy to process, and also used to manufacture DRIVER heads.

7, Putting material: stainless steel, brass, bronze, copper, polymer, polyurethane, aluminum, stainless steel.
