Tungsten alloy is right material for tennis rackets or the like to change the swing force and impact center known as the "sweet spot" on a tennis racket and more particularly relates to a snap-on weight that can be easily attached or removed.
This invention relates to extrusion dies useful for processing both non-ferrous metals and alloy steels, the dies being made of a predominant amount of molybdenum or tungsten, the remainder being zirconia. This invention relates to extrusion dies useful for processing both non-ferrous metals and alloy steels, the dies being made of a predominant amount of molybdenum or tungsten, the remainder being zirconia. Extrusion die is usually used in the multiple extrusion process which is specially designed to prevent delamination or cracking of the rods during extrusion.
Bucking bar is a work tool received behind work surfaces to provide a backing member in applying impact fasteners and including intermitted toolhead and handle parts with a low-recoil impact-absorbing spacer provided there between to take shock loads in compression and shear.
Probably the most well known application for tungsten alloy is the aerospace industry, where weights and counterweights are often required to be housed in restricted areas. With significant reductions in size possible, this in turn, leads to greater control of weight distribution. These components can increase the sensitivity of control mechanisms and keep the forces required to operate flight controls within acceptable limits.
Drivers consistently report they can sense differences in how a car handles on the track if the weight on a given wheel varies only by a couple of pounds. Fine tuning a car to a given track is a very cumbersome and time consuming ordeal with conventional lead plate weights. WHA weight blocks offer up to 50% more weight in a given volume, with the added advantages of direct attachment via threaded holes or thru-bolting and the freedom from deformation.
Tungsten weights are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. Tungsten weights are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart. Tungsten weights are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.
As we know, the barrel forms the main part of a dart. Nowadays, tungsten-based heavy alloy billet is widely used as the standard barrel material, for it has a specific gravity of 19.3(20℃), making it a very dense material with small volume. Besides, it has superior wearing resistance, well machinability, etc.
Tungsten Heavy Alloys (WHAs) are the best choice when Designers in aerospace and defense industries require a material which combines high density, good mechanical strength and which is easily machined. The high density of WHAs makes it possible to significantly reduce the physical size of components. This in turn, gives the benefit of greater control of weight distribution and increases the sensitivity of controlling mechanisms. Where a large mass must be housed within a restricted area, WHAs are the ideal material.
Nowadays, modern engine is often made from special metal alloys, and much lighter than earlier engines. So the powder and performance of a modern engine are increased. Also, material for crankshaft has been improved, and tungsten alloy is more and more used as the material for crankshaft.
We can offer golf club head with a sole component entirely composed of a tungsten alloy material. We adopt the method of Metal Injection Molding, making an entire golf club head composed of a metal injection molded material having a tungsten alloy composition.
Tungsten alloy is a suitable raw material for radiation protection, as its combination of radiographic density (more than 60% denser than lead), machinability, good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle and high strength. It can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides, compared with lead or depleted uranium in the past, tungsten alloy is more acceptable in this case, for they are non-toxic.
Tungsten Heavy Alloys (WHAs) are tungsten alloys that typically contain 90 to 98 wt% W. Most commercial tungsten alloys are two-phase structures, the principal phase being nearly pure tungsten in association with a binder phase containing the transition metals plus dissolved tungsten. As a consequence, WHAs derives their fundamental properties from those of the principal tungsten phase, which provides for both high density and high elastic stiffness. It is these two properties that give rise to must applications for this family of materials.
The majority of current uses for WHAs are best satisfied with the W-Ni-Fe system. such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe is a common approach for slight enhancement of both strength and ductility. The presence of cobalt provides solid-solution strengthening of the binder and slightly enhanced tungsten-matrix interfacial strength. Cobalt additions of 5 to 15% of the nominal binder weight fraction arc most common.
The current uses of tungsten alloy (WHAs) are spanning a wide range of consumer, industrial, and government applications that include:
Damping weights for computer disk drive heads
Balancing weights for ailerons in commercial aircraft, helicopter rotors, and for guided missiles.
Kinetic energy penetrators for defeating heavy armor
Radiation shielding, radio isotope containers and collimation apertures for cancer therapy devices
High performance lead-free shot for waterfowl hunting.
Weight distribution adjustment in sailboats and race cars.
Many applications that require high gravimetric density for balance weights, inertial masses, or kinetic energy penetrators or high radiographic density for radiation shielding and collimation necessitate rather large bulk shapes. Such a requirement eliminates all but a few candidates on the basis of prohibitive cost, typically reducing the choice of very dense alloys down to either tungsten- or uranium-base materials.
