1) Machine tools
Tungsten carbide cutting surfaces are often used for machining through materials such as carbon or stainless steel, as well as in situations where other tools would wear away, such as high-quantity production runs. Most of the time, carbide will leave a better finish on the part, and allow faster machining. Carbide tools can also withstand higher temperatures than standard high speed steel tools. The material is usually called cemented carbide, hardmetal or tungsten-carbide cobalt: it is a metal matrix composite where tungsten carbide particles are the aggregate and metallic cobalt serves as the matrix.

2)  Military
a) Tungsten carbide 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 German Luftwaffe tank-hunter squadrons, which used 37 mm autocannon equipped Junkers Ju 87G dive bomber aircraft to destroy Soviet T-34 tanks in World War II. 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-Ulrich Rudel. It is an effective penetrator due to its high hardness value combined with a very high density.

b) Tungsten carbide 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.

c) Tungsten carbide 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 tungsten carbide brick onto a plutonium sphere, causing the sub-critical mass to go critical with the reflected.

Tungsten alloy swaging rod is made of tungsten rod. The density, hardness and strength of tungsten alloy swaging rod is higher than tungsten alloy rod. Tungsten alloy swaging rod has been widely used for CBU-24.

The CBU-24 (Cluster Bomb Unit-24) is an unguided, aircraft delivered anti-personnel and anti-materiel weapon developed by the United States. Because it is an unguided weapon, the CBU-24 can be carried and dropped by any aircraft capable of carrying standard "dumb" or "iron" bombs.

The CBU-24 cluster bomb consists of a SUU-30 dispenser unit containing a payload of 665 tennis ball-sized BLU-26 or BLU-36 fragmentation submunitions, also known as bomblets.[1] Once dropped from the delivery aircraft, the CBU-24 casing breaks open in-flight and releases the individual submunitions, scattering them over a large area.

CBU-24 contains shaped charge warheads which made by tungsten alloy swaging rod to pierce armor and destroy tanks.

Tungsten alloy swaging rod is made of tungsten rod. The density, hardness and strength of tungsten alloy swaging rod is higher than tungsten alloy rod. Tungsten alloy swaging rod has been widely used for JDAM.

JDAM is a guidance kit that converts unguided bombs, or "dumb bombs" into all-weather "smart" munitions. JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km). JDAM-equipped bombs range from 500 pounds (227 kg) to 2,000 pounds (907 kg). When installed on a bomb, the JDAM kit is given a GBU (Guided Bomb Unit) nomenclature, superseding the Mark 80 or BLU (Bomb, Live Unit) nomenclature of the bomb to which it is attached.

JDAM contains shaped charge warheads which made by tungsten alloy swaging rod to destroy undergound bunkers.

Tungsten alloy swaging rod is made of tungsten rod. The density, hardness and strength of tungsten alloy swaging rod is higher than tungsten alloy rod. Tungsten alloy swaging rod has been widely used for BL755.

BL755 is a cluster bomb. Its primary targets are armored vehicles and tanks with secondary soft target (anti personnel) capabilities.

The MW-1 was designed so that different types of submunitions may be loaded into its 112 tubes. The MIFF, MUSA and MUSPA mines are parachute dropped, and upon reaching the ground self-right and arm. The mines are blast-resistant and are reported to have a self-destruct devices giving them a lifespan of less than forty days.

The BL755 looks like a standard 450 kilograms (1,000 lb) general purpose bomb but with a hard "saddle" on the spine for ejector release and crutching pad loads and a distinctive large turbine-like air arming vane on the nose. The four rear fins are squared off in appearance, but on closer inspection can be seen to be hollow and telescopic. A central extruded aluminum skeleton provides seven bays long by seven bays around, each containing 21 submunitions (147 total). The submunitions are ejected by means of a central cartridge and individual inflatable bladders for each bay, operating in a similar manner to a car airbag. Ejection on the original BL755 bomb is triggered by the rotation of the arming vane, driven by the airflow.

BL755 contains shaped charge warheads which made by tungsten alloy swaging rod to pierce armor and destroy tanks.
