1. Carbon material: mainly used to make carbon shafts.
Generally, ceramic components are added to graphite, or carbon and glass fibers are added. This will make it lighter and stronger;
2. Titanium alloy: generally used to make DRIVER heads.
The density of titanium is quite small, about 60% of iron. But it has the characteristics of high strength, easy high temperature heat treatment, weldability and forgeability. Titanium alloy refers to the addition of other metals to pure titanium to improve its characteristics.
6–4 Titanium: 6% aluminum and 4% alum are added to pure titanium-mostly used for casting club heads.
Beta titanium (in the usual sense) — Add 15% alum, 3% chromium, 3% aluminum, 3% nickel to pure titanium, and use forged heads.
SP700 is similar in performance to the 15-3-3-3β titanium mentioned above, and belongs to high-quality β titanium.
3. Tungsten: The density of tungsten is quite high, about 4.5 times that of titanium, and it is mostly used for club head weights.
4. Mild steel: soft iron. When casting iron rods, 2~4% carbon is added to the stainless steel to make it very hard;
When forging, add 0.1~0.3% carbon to soften;
5.stainless steel: stainless steel
—-sus630— mostly used for casting, earlier used for PING’s famous back-hole cast iron rods, widely used for iron rods and wood rods.
—-sus304, it is softer than sus630.
6. Other materials:
Beryllium copper: (copper + 1%~~2.5% beryllium), which is about 6-7% heavier than stainless steel —- mostly used in the manufacture of wedges.
Aluminum alloy: (aluminum + 4%-6% lead and 2%-3% magnesium), which is lighter, stronger and easier to process. It is also used to make DRIVER heads.
7. Putter material: stainless steel, brass, bronze, copper, polymer, polyurethane, aluminum, stainless steel.
