|Thread: Machining Tungsten|
The DENAL density is 17.5 (19.3 for pure tungsten). The copper/tungsten alloy (used for EDM electrodes) density is only 14.
Surch for DENAL on the web it's an alloy 93% tungsten with iron nickel and cobalt I used it for making boring bars (for low vibration) it's machinable while tungsten is not, but you must use TC taps (I killed HSS ones in this stuff).
