Advantages of Tungsten Alloy Cube for Military Application

We can produce all kinds of tungsten alloy cubes and we can design tungsten alloy cube which could be manufactured as the parts of military defense,tungsten alloy cubes for military is widely used in extrusion die, some counterweights, such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc.

Why we adopt tungsten alloy cube for parts of extrusion die instead of lead or aluminum or other materials' block? Because tungsten alloy has high melting point more than ten times higher than lead, which is important in extrusion die process. Then, tungsten alloy has high Mohs hardness. What is the most important reason is that tungsten alloy is environment friendly, which lead can not reach.

Since at least World War II, tungsten alloys have proven their worth in ordnance applications. Hyper-velocity armor-penetrating applications use our materials in balls, cubes, and projectile shapes. Manufacturing techniques and additives allow us to vary certain properties, such as elongation, ultimate tensile strength, and hardness, of our tungsten alloys in order to meet your needs.

Tungsten Combustion Chamber of Turbo Engines

Conventional combustion chambers are generally of optimized rating for take-off or near take-off operation. This signifies that, in the primary zone of the combustion chamber, a fraction of the air flow of the compressor is introduced so that, with the injected fuel, the fuel-air mixture in this zone would be essentially stoichiometric in turbo engines. Under these conditions, due to the levels of temperature and high pressures, as complete as possible a combustion is obtained, combustion yields greater than 0.99 are attained, the speeds of the chemical reaction being optimum for these stoichimoetric mixtures. 

In addition, the pressures and temperatures at the outlet of the compressor are lower; the result is that the chamber, with the partial charge is very much maladjusted and that the slow speed combustion efficiency rarely goes beyond 0.93. The combustion is, therefore, very incomplete, which means much higher concentrations of carbon monoxide and unburnt residues at the exhaust than under normal operation. The proportions of the pollutants are all the higher, the lower the total yield of the combustion. 

The fresh gas/burnt gas mixture must also be advantageous because it contributes to the increase in the temperature of the carburized mixture and, therefore, aids in its atomization and consequently permits an improvement in the speed of the chemical reaction. In conventionally allowing this contact of the carburized mixture with the high temperature gas from the combustion it is desirable to arrange for a recirculation of the latter by searching for a convenient turbulence level.

All of these solutions, which allow an improvement in the combustion yield have, however, a maximum efficiency only for values sufficient for the pressures and temperatures of the air at the chamber inlet.

Tungsten Alloy Advantages

There are some main properties for tungsten heavy alloy as follows:

-High Density: high density between 16.5 and 18.6 g/cc with tungsten content from 80%W to 97%W.

-High Melting Point: the highest melting point as 3,422 C, 6,192 F and the highest tensile strength. -Excellent Hardness: almost from 24 HRC to 36 HRC, or even above 40 HRC through swaging.

- Superior Wearing Resistance: excellent wearing resistance in high concentrations of CO2、H2S、Cl- corrosion environments.

-High Ultimate Tensile Strength: excellent properties almost for products used in military or other high-tech filed.

-High Temperature Resistance: optimum parameters had been obtained as bonding temperature 1403K, bonding time 50min, bonding pressure 7.5MPa and cooling velocity 5K/min

-Non-toxic and Environmental Friendly: compared with lead, tungsten heavy alloy is an ideal, environmentally friendly, and is of non-toxic.

-Good Corrosion Resistance: corrosion resistance sulfur jar mandrel; stuffing box and other products，whose corrosion-resistant and wear-resistance have reached the international advanced level.

-Well Machinability: relatively easy to machine, and can be plated or painted to enhance their corrosion protection.

-High Radiation Adsorption Capability: At the same weights high density alloy can provide the same energy absorption as lead using 1/3 less material.

-High Impact Resistance and Crack Resistance: It is defined as the amount of energy per volume that a material can absorb before rupturing.

Tungsten Alloy Bar

Tungsten alloy bar is consist of 85-99% tungsten with balanced commonly nickel and iron or copper. The alloys are made by liquid-phase sintering to give a structure consisting of almost pure tungsten particles in a matrix of the alloy elements. Tungsten heavy alloy, with densities between 15.8 and 18.75 g/cm3, represent the heaviest materials generally available to the engineer. It has excellent radiation resistance, thermal and electric conductivities, corrosion resistance and machinable.

Tungsten Alloy Extrusion Die Advantages

Hard steel wire is generally made by forcing solid metal through a hole, called a die, under such intense pressure that it is extruded like pasta.
However, can you imagine the incredible forces that must be acting on the holes? In some cases diamond or sapphire (nearly as hard) dies are used, but this one is made of a tungsten alloy, probably because of its high strength even at very high temperatures.
On account of its prosperities of high heat resistance, good hardness, excellent plasticity ability, tungsten heavy alloy (WHA) is quite suitable material for tolls such as extrusion dies, die casting components, etc., especially when it is employed in extrusion die of copper related alloy, the manufacture of aluminum, zinc and brass castings. Extrusion dies are made from a sintered material consisting of Mo and/or W containing 2-60% by volume of high melting point non-metallic components which are free from oxygen (except possibly in impurity amounts).
