What's Tungsten Copper Alloy?


Tungsten copper alloy (copper tungsten alloy, CuW, or WCu) is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to be machined. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper.

In its elemental form tungsten's CAS number is 7440-33-7. The tungsten atom has a radius of 137.pm and its Van der Waals radius is 200.pm. Tungsten is considered to be only mildly toxic. Tungsten has the highest melting point of all the metallic elements and was first commercially used in incandescent and fluorescent light bulb filaments, and, later, in early television tubes. The first imaging equipment involved X-ray bombardment of a tungsten target. In January 2013, Kansas State University researchers demonstrated a new nanolayer synthesis method by quickly and efficiently creating layers of tungsten disulfide with structural similarity to graphene, making them a potentially cost-effective nanomaterial for use in lithium-ion batteries in the future. Tungsten expands at nearly the same rate as borosilicate glass and is used to make metal to glass seals. It is the primary metal in heating elements for electric furnaces and in any components where high pressure/temperature environments are expected, such as aerospace and engine systems. Tungsten is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, andcompounds as submicron and nanopowder. Tungsten is found in the minerals wolframite, scheelite, ferberit and hübnerite and was first discovered by Fausto and Juan Jose de Elhuyar in 1783. In reference to its density, Tungsten gets its name from the swedish words tung and sten meaning heavy stone. See Tungsten research below.

In its elemental form copper's CAS number is 7440-50-8. The copper atom has a radius of 127.8 .pm and its Van der Waals radius is 140.pm. Copper is an essential trace element in animals and plants, but in excess copper is toxic. Due to its high electrical conductivity, large amounts of copper are used by the electrical industry for wire. Of all pure metals, only silver has a higher electrical conductivity. Recent research reveals that diluted magnetic semiconductors can be produced using Copper. Copper is also resistant to corrosion caused by moisture, making it a widely used material in pipes, coins, and jewelry. Copper is often too soft for its applications, so it is incorporated in numerous alloys. For example, brass is a copper-zinc alloy, and bronze is a copper-tin alloy. Copper sulfate (CuSO4· H2O), also known as blue vitrol, is the most well-known copper compound. It is used as an agricultural poison, an algicide, and as a pigment for inks. Cuprous chloride (CuCl) is a powder used to absorb carbon dioxide (CO2). Copper cyanide (CuCN) is often used in electroplating applications.

Tungsten Copper Military Shaped Charge Liner

Tungsten copper military shaped charge liner is part of armor-piercing projectile which plays an important role in action. Commonly used shaped charge liner is taper angle form. Generally, cone angle is ranging from 120 to 160 degrees.

Armor-piercing projectile rely on kinetic energy of the projectile to penetrate armor and destroy the target. Armor-piercing projectile are high velocity, long shooting distance and high precision of shooting, is the main ammunition of tank guns and the anti-tank guns. It also used in naval gun, coastal gun , anti-aircraft artillery and airborne cannon and used for mutilating tanks, self-propelled guns, armored vehicles, ships, aircraft, etc.

The theory of tungsten copper military shaped charge liner is called cavity effect .When the armor-piercing projectile detonates, the high temperature and high pressure instantaniously melting shaped charge ,then forming high temperature and speed metal jet which can sear even burnthrough the armored steel. So it is show that armor-piercing projectile take effective action by the cavity effect rather than rely on the kinetic energy.

Armor-piercing projectile’s armor ability is different when adopting different material of shaped charge. Copper used as material for shaped charge liner with low melting point and good ductility, however the density of copper is low and easily deformation, so it commonly mixed with tungsten to improve the density, which increase the armor ability of tungsten copper military shaped charge liner.

Tungsten Copper Military Alloy

There are many methods making tungsten copper military alloy.
Traditionally, tungsten copper military alloy making commonly adopt copper permeability and liquid sintering technique. However as tungsten and copper indissolve each other and the sintering sex also poorer, it is difficult to implement fully sintering to optimize dense and form the uniform microstructure, and also hard to flexible adjustment of composition of copper tungsten. The followings are the commonly.

Infiltration Method
Infiltration method is that firstly prepare fixed density and strength of porous tungsten substrate skeleton, than infiltrate low melting point mental copper into the tungsten skeleton.

The mechanism of infiltration method is when the liquid copper wetting tungsten porous substrate, under capillary pressure, the liquid copper flow long with the particle’s porous skeleton and padding the porous skeleton, resulting in comprehensive good materials.

The merits of tungsten copper military alloy made from this method are high density, good sintering performance, good thermal and electricity conductivity. However, this tungsten copper military alloy needs further machining, which increase the machining cost, reduce the yield.
High temperature liquid sintering method

As there is a huge distance between the tungsten and copper of the melting point, so we can adopt high temperature liquid sintering method to make tungsten copper military alloy, through which densificate its density at the temperature higher than copper melting point.

This method’s advantage is that the processing is simple and easily control, while high sintering temperature, long sintering time and low sintering density which make the finished products can not meet the requirements of usage. In order to improve the density, repress, hot –press and hot forging after liquid sintering.

Arc melting method
Arc melting method is making into electrode with the copper tungsten, then melting in the arc furnace, so tiny grain, low density ,high densify and good corrosion resistance tungsten copper military alloy come out.
