Qualitative beta titanium. 3, tungsten: tungsten density is quite large, about 4.5 times of
titanium, more for stem head counterweight. Tungsten (19.5) 4, mild steel: soft iron in
casting iron. When in stainless steel, add the
2 to 4% of the carbon that becomes very hard;
Forging, add 0.1 ~ 0.3% of carbon, can become
soft; Stainless steel, stainless steel, 5-
sus630 (added 17% 4% chromium and nickel)-more for casting, earlier for the PING famous back
empty type cast iron, now widely used in iron
and wood pole. -sus304 (added 18% chromium and
nickel 8%), it sus630 than soft. 6, other materials:
beryllium copper: (copper + 1% ~ 2.5% in
the beryllium), than stainless steel weighing about 6-7%-often used to make dig up stem.
Aluminum alloy: (+ 4%-6% aluminum lead and 2% 3% magnesium), lighter, stronger and easy
processing, also used in the manufacture of
DRIVER stem head. 7, push rod materials:
stainless steel, copper, bronze, copper, polymer, polyurethane, aluminum, stainless steel
