tungsten powder

Description:
High density, spheroidal Tungsten powder
Appearance:
Gray metallic powder
Physical Properties:
Particle Size: Minimum 85% > 70 Microns
Particle Size Distribution: Minimum 90% between 100 and 200 Mesh
Bulk Density: Minimum 18.50 g/cc (Helium Pycnometer)
Tap Density: Minimum 11.90 g/cc (ASTM B527)
Applications:
Tungsten powder is are widely used in the production of weight fillers, radiation shielding fillers and induction accelerators, etc.. The thin film surface of its polymer mixture is ideally suitable for radiation protection. The large particle size makes it an ideal heavy metal filler for injection-molding applications. The unique shape and the resulted high flow ability of the particles make it suitable for applications in metal spray industry

pure tungsten

Pure tungsten is the material for producing pure tungsten products. Pure wolfram is so-called pure for its purity is over 99.95%. Products made of pure tungsten have the highest density among the tungsten products, including tungsten alloy and tungsten carbide products. Pure tungsten products are preferred by customers for its high density, high temperature resistance, high corrosion resistance, high wear resistance, high hardness, and low thermal expansion.

Introduction of Tungsten-2

The higher density tungsten heavy alloy has been used in medical instruments (e.g. X-ray machines, gamma-ray machines) as widely, the most important of tungsten alloy in medical is used as anti-radiation materials, such as tungsten alloy resource holder, tungsten alloy radiation shielding for uranium, depleted uranium (DU) protection shields. Tungsten alloy shielding for X-ray and gamma-ray, After the issue of the Japanese Uranium Powder Station, the newest tungsten alloy products for anti radiation are the materials of something as “Tungsten Plastic” for the application of tungsten protection coats of Uranium Powder Station

Tungsten Putty is another new application for the application of weighting such as tungsten fishing sinker, racing car’s weight, such as and tungsten putty for pinewood derby cars. Tungsten putty is a material made from tungsten powder and a polymer binder, the minimum density of tungsten putty is 10g/cm3.Tungsten Putty is non-hardening and easy to mold and shape to any form, so that you can have any design you want, and is easy to apply and will not dry out even after several weeks exposed to air and sunlight.

Introduction of Tungsten

Tungsten /tʌŋstən/, also known as wolfram /wʊlfrəm/, which is a chemical element with the symbol of W and atomic number 74. Tungsten Metal is a hard, rare metal, it was found naturally on the Earth only in chemical compounds such as tungsten oxide. Now, the most of tungsten mines was found in China.

Tungsten metal it is also named pure tungsten, the unalloyed elemental form of tungsten is used mainly in electrical applications, for example, most notably in incandescent tungsten light bulb filaments, X-ray tubes (as both the tungsten filament and tungsten target), tungsten electrodes and also tungsten metal always used in tungsten steel.

Tungsten metal has many different alloys which have numerous applications. Tungsten alloy always called super alloys, for the high density and nice TRS of tungsten alloy may used as military applications in penetrating projectiles, aircraft and helicopter jets' parts, aircraft and helicopter breaking plates and shoes, and our tungsten alloy swaged rod with perfect physical properties can be used for bullets of antitank missiles and canons' bullet, especially tungsten alloy cubes can be used for smart bomb (e.g. AHEAD); and other military applications. Also, tungsten alloy always used as tungsten alloy counterweight and tungsten alloy balance weight
