Tungstencarbide is often used in armor-piercing ammunition, especially where depleted uranium is not available or not politically acceptable. The first use of W2C projectiles occurred in Luftwaffe tank-hunter squadrons, which used 37 mm autocannon equipped Ju-87G Stuka attack planes to destroy Soviet T-34 tanks in WWII. Owing to the limited German reserves of tungsten, W2C material was reserved for making machine tools and small numbers of projectiles for the most elite combat pilots, like Hans Rudel. It is an effective penetrator due to its high hardness value combined with a very high density.
Tungstencarbide ammunition can be of the sabot type
(a large arrow surrounded by a discarding push cylinder) or a
subcaliber ammunition, where copper or other relatively soft material
is used to encase the hard penetrating core, the two parts being
separated only on impact. The latter is more common in small-caliber
arms, while sabots are usually reserved for artillery use.
Tungstencarbide is also an effective neutron reflector and as such was used during early investigations into nuclear chain reactions, particularly for weapons. A criticality accident occurred at Los Alamos National Laboratory on 21 August 1945 when Harry K. Daghlian, Jr. accidentally dropped a tungstencarbide brick onto a plutonium sphere causing the sub-critical mass to go critical with the reflected neutrons.
