TUNGSTEN TECHNOLOGY
| Tungsten has been used since the 1970’s for the production of darts, because it is twice as dense (heavy) as brass. A dart made of tungsten will be half the size of its brass equivalent. This means that it is easier for the player to achieve close grouping and score the maximum 180! | |||
Tungsten is found in igneous rock. It is crushed to powder and the tungsten content is separated out. |
Pure Tungsten powder ready to be sintered with nickel in a furnace at 3000ºC. |
100% Tungsten is very brittle. It is necessary to create an alloy by combining the tungsten powder with iron, nickel, and zinc. |
Sintered tungsten billets are cut to size, then “drilled and tapped”. High technology machinery turns a billet into a dart barrel. |
