Carbide (Or rather called Tungsten Carbide and Titanium Carbide) is normal materials which are widely used for any kinds of cutting tools. For example: Saw Blades, Lathe Tools, Drill, Turning and Milling Tools and Dental Bits are always made from Carbide Materials. Carbide is widely used at these tools because carbide's wear-resistant, sharper and useful time is longer than other materials. In additional, carbide balls are also used in pen tips, because it is more wear-resistant.
 
Like tools of tungsten carbide saw blades, its main body is made from Steel. Tungsten carbide tips are brazed on the saw blades. Fine-quality tungsten carbide tips is excellent wear-resistant, its useful time can up to 20 times than Steel tips.
 
Tungsten carbide tips has turned in the last, but you can re-grind them just like you grind steel tools, but tungsten carbide tips is harder, so grinding tools is different. Normally, we use diamond tools or tungsten carbide grinding wheels.
 
Most of the whole tools are not made from carbide, because carbide's price is very expensive and it is very brittle. So, steel is better materials which are used for making main body, it is more stronger, not easy to crack and broken.

The 35mm by 228mm AHEAD ammunition is an original cartridge type, programmed detonator ammunition, composed of a Programmable Fuze System, tungsten alloy subprojectiles, ejection standoff ammunition, a thin-walled body, nitrified fibre firing ammunition and steel ammunition cartridge. This tungsten military defense is become more and more widely used in the military field.

In the anti-missile role it uses Advanced Hit Efficiency And Destruction (AHEAD) ammunition. This round ejects 152 tungsten projectiles at a predetermined distance, between 40 and 10 m, from the target. A 25-round burst of AHEAD rounds produces 3,800 of these small projectiles to destroy the incoming missile. Cruise missiles can be destroyed at 2.5 km and high speed missiles at 1.5 km range by tungsten military defense. A more common projectile to see in service is the advanced hit efficiency and destruction [AHEAD] round. Given the size of the diameter and the larger length of the projectile, as opposed to a 35mm AHEAD round, more tungsten alloy subprojectiles are carried - one hundred and eighty as opposed to one hundred and fifty-two . The submunitions of this tungsten military defense are tungsten-alloy [WHA] spheres, designed for both penetration and 'mass effect', to increase the likelihood of engaging the incoming 'vampire' or 'bogie'. The round is termed the MCP170 and uses a programmable magnetic fuze which uses information provided by the coil velocity gauge near the gun's muzzle in order to automatically compute the correct estimated time to target.

The combat efficiency of the AHEAD ammunition is due to the payload of 152 tungsten alloy subprojectiles weighing 3.3 grams each. These subprojectiles are activated at a certain distance in front of the intercepted target, forming a mass of lethal subprojectiles, greatly augmenting the probability of a kill. The tungsten alloy subprojectiles have a sharp edge, ensuring that this tungsten military defense can inroad into the target with precise accuracy, tungsten military defense also provides the kinetic energy to destroy the electrical components, payloads or motor of the target.

Tungsten alloy shielding is necessary for nuclear scale. Nuclear scale utilizes rays which released by radioactive isotope and absorbed partially or scattered to realize quantification when rays pass through matters. Nuclear scale is used to measure the matters in transport system. Radioactive source and receiver are located on the upper side and downside of conveyer belt. According to counting rate that rays pass through matters, nuclear scale can weigh the amount of matter in delivering constantly. More regular and even sizes of matters are, the higher accuracy is. Nuclear scale is primary used for measuring dynamic matters. It has been widely used in building materials, coal, chemical industry or other industries. It can be also used for various kinds of conveyor such as scraper, screwing and anchor chain.

The radioactive sources of nuclear scale are ⁶⁰Co and ¹³⁷Cs.

Tungsten alloy shielding for nuclear scale can protect staffs from radiation. The density of tungsten alloy is higher twice than lead. The high density allows a reduction in sized of shielding components without compromising effectiveness of shielding characteristics. Otherwise tungsten alloy has the advantage of non-toxicity.

Radioactivity logging is physical geographical method which used for researching geologic section of oil drilling, seeking oil, coal or other mineral resources and researching drilling engineering. Radioactivity logging has been widely used in prospection for coal field, uranium mine and oil and becomes one of important measures.

Both nuclear instrument and radioactivity logging utilize characteristics of α-ray, β-ray, γ-ray and neutron ray which released by radioactive isotope. Radioactive source, made of radioactive isotope which can releaseα-ray is called as α radioactive source. Radioactive source, made of radioactive isotope which can releaseβ-ray is called as β radioactive source. Radioactive source, made of radioactive isotope which can release neutron ray is called as neutron radioactive source

Compared with traditional material like lead, tungsten alloy shielding is more suitable for radioactivity logging. The density of tungsten alloy is higher twice than lead. So tungsten alloy has excellent radiation absorption. Otherwise, tungsten alloy is non-toxicity.

The principle of tungsten alloy accelerator is that electron is produced by electron gun which is under vacuum. It is located on the exine of cavity resonator. Radial electric gives energy to the electrons after they shooting. Electrons are accelerated. Electrons move to cavity resonator when they are accelerated firstly. Then they pass through the holes on the center of electric conductor. When electrons appear inside cavity resonator after passing through hole, electric steering accelerator electrons secondly and electrons achieve a diameter movement. Electrons, having been accelerated are got back to cavity resonator and accelerated again. The shape of electrons moving path is like a rose. So the tungsten alloy accelerator is called as Rhodotron. At exist of tungsten alloy accelerator, pillar high energy electron beam shoots to irradiation chamber, under the transferring or guiding of the beam line. Then, electron beam passes through the vacuum and enters into atmosphere. Electron beam scans back and forth and passes through the products on the conveyer belt after spread.

The density of tungsten alloy accelerator is twice higher than lead. The high density allows a reduction in physical sizes of accelerator without compromising effectiveness of shielding characteristics. Otherwise, high density means better radiation aborption.

Nowadays, tungsten alloy is increasingly adopted as the raw material for military defense, and works as tungsten alloy military fitting, such as bullet, armor and shells, shrapnel head, grenade, bulletproof vehicles, tanks panzers, cannons, firearms, etc. A major tungsten alloy military fitting is in kinetic energy penetrators, where military defenses are in direct competition with depleted uranium (DU). Recent investigations conducted at the Army Research Laboratory show that DU's superior properties resulted from its ability to localize shear during ballistic penetration events. Therefore, military defense was argued that if localized shear can be imparted to tungsten alloy, this material would exhibit penetration performance matching that of depleted uranium (which had become an environmental problem).

You can image the subject envisions a penetrator, dropped from service height of a bomber aircraft, using kinetic energy to penetrate the shielding, and subsequently deliver a nuclear explosive to the buried target.

The problem with such a penetrator is the tremendous heat applied to the penetrator unit when striking the military defense shielding (surface) at hundreds of meters per second. Military defense has partially been solved by using metals such as tungsten (with a much higher melting point than steel), and altering the shape of the projectile (such as an olive).

In earlier time, people usually did mining primarily with pick axes and shovels, which relied on pure manpowere to get the job done. And later, with tools made of steel, cuz steel tools could do better job, and they were susceptible to wear. However, with the development of tungsten carbide industry, tungsten carbide products are widely used in mining work, especially tungsten carbide coated tools.

Then came tungsten carbide tools. Since tools made of tungsten carbide are tougher and more wear-resistant, these tools are able to perform their job faster and for a longer time when compared to steel tools.

The mining industry has one of the highest demands for tools that have high wear-resistant, just like tungsten carbide coated tools, as working in a mine involves cutting through hard rock, often spanning several miles. Having tungsten carbide coated tools that are resistant to wear means the company doesn’t have to replace their tools often, preventing money lost due to down times. Thus, there is a need for tungsten carbide coated tools that do not wear out easily, ensuring continued productivity for longer periods of time.

Mining companies are always on the lookout for more abrasion resistant tools beyond the usual tungsten carbide coated tools. Cemented carbide was developed by combining tungsten carbide, titanium carbide, tantalum carbide, and cobalt. This combination is even harder than regular carbine, while further improving ordinary tungsten carbine’s heat resistance ability.

Diamond may also be added to the tools, as diamond is the toughest material on the planet, which can easily cut through practically any material.

Tungsten alloy counterweight is widely used as counterbalance an opposing mass in a linear or rotary motion system as for its counterweight.

Tungsten alloy counterweight is always used for counterbalance an opposing mass in a linear or rotary motion system, allowing movement with lower driving forces.

Tungsten alloy counterweight is designed for aircraft control surfaces, aircraft rotor blades, guidance platforms, and vibration dampening governors. Take vibration dampening governor for instance, tungsten counterweight is used to reduce vibrations in rotating systems such as automobile tires. The vibration is measured without any weights and the heavy spot is determined. It is then placed opposite this heavy spot to balance the load and reduce or eliminate the vibration.

The reasons for adopting tungsten can also be made out of metals such as iron, steel and various alloys. However, tungsten alloy with high density becomes the most popular used material. Take tungsten alloy golf counterweight for instance. When counterweight golf, somebody have the thought of that if they want more distance and control, the conventional wisdom calls for lighter overall weight. But it turned out to be wrong.
