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.

Choose the best material, all will tested by our quality department, and before loading, we will test all, in order to supply you the best products.

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).

Tungsten Alloy Tube

Tungsten alloy tube has high melting temperature, high strength, good thermal conductivity and spalling resistance. It can be used as the parts of electron tubes and the heating elements of the high temperature furnace.
It is also mainly used for high temperature furnace components, crucible, missile rockets nozzle high temperature furnace, etc.

Why Use Tungsten Alloy for Hunting Shot?

High density, great hardness and resistance to high temperature make tungsten to be one of the most sought-after materials for shotgun pellets in shooting history. The density of tungsten alloy is about 18g/cm3, only gold, platinum, and a few other rare metals have a similar density. So it is denser than any other shot material, including lead, steel or bismuth. To understand how the density factors into performance, let’s look at two spheres about the same size, a golf ball and a ping-pong ball. The golf ball is far denser and will fly farther and hit harder. Now reduce that size down to two single No. 4 pellets, one steel and the other a tungsten alloy. Get the picture? The tungsten will fly farther, hit harder and penetrate deeper. That means more birds, farther out, with fewer cripples. Another unique property of tungsten is that it is non-toxic, it is friendly to the environment, so tungsten alloy hunting shot is safe for people to handle and work with.
