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.
Tungsten Alloy Trim Weights
Vibrations in the dynamic components of aircraft engines and propeller systems are highly undesirable. Vibration, caused by mass imbalance of externally rotating components, can be reduced or eliminated by using mass trim weights. Additionally, counterweights are incorporated into the pitch control systems of many propeller designs as a failsafe mechanism. During flight the propellers are kept at the correct angle by hydraulic pressure counterbalances to optimize performance. Tungsten alloy offer designers several advantages over conventional balance materials such as lead or steel. The higher density of the alloys permits smaller components to be used, reducing overall system weight. Unlike lead, which can exhibit creep at ambient temperatures, these alloys are stable and so may be used in mechanically stressed positions without the need for additional fabrication and encasement.
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.
A small weight or weights added around the perimeter of the frame, forming the tennis racket head, can result in a swing that is normally slightly off the impact center, being now "on" improving accuracy and power which increases the speed and control of the ball. One such method of adding weight is by tape on the inside surface of the frame. However a disadvantage of this method is that it must be done when re-stringing the racket and the weight cannot be repositioned without removing and replacing the strings.It is, therefore, one object of the present product to provide a snap-on weight for tennis rackets that allows a player to vary the weight distribution of a tennis racket. The position of the weight can be changed at will.
Tungsten heavy alloy (WHA) balance weight of racing car is now becoming the most popular material for ballast, due to its main advantages as follows:
Adding WHA balance weight into the whole framework of a racing car is helpful to optimize the performance of the racing car during the racing progress, which contributes to the better control of the car's movement.
High tensile strength and good creep resistance
Tungsten has high tensile strength and good creep resistance with a high mass/size ratio, so it will be the ideal to work in a restricted space. Its high density also gives enhanced sensitivity by increasing the control of load distribution.
WHA is also easily machineable which gives designers greater flexibility in deciding on the final shape of components and offer designers several advantages over conventional balance materials e.g. lead or steel.
Our tungsten alloy can be used in:
High environmental compatibility, lower fuel consumption, and improved electronics for more comfort and safety in modern vehicles set high demands for applied materials. Tungsten and molybdenum products of us made from high performance materials advance to new levels of achievement and guarantee maximum efficiency.
Increasing service temperatures and compact, space-saving designs are the demands of the engine generations of the future. High performance tungsten and molybdenum products are best suitable for applications in engines because of their mechanical, chemical, physical and tribological properties. Components made of tungsten heavy alloy with densities up to 18,5 g/cm3 are well-suited for highly effective crankshaft and flywheel balance weights in standard production cars, in racing, shipping or the industrial engine sector.
The minimum weight requirements of motor sport formulae are often met with ease as more exotic materials give designers the ability to create lighter and stronger components in the search for greater performance.
Adding our ballast weight helps to provide competitive advantage by giving the ability to add ballast within confined spaces in exactly the correct place to both trim the weight distribution and lower the centre of gravity of a competition car and still meet the minimum weight requirements.
A lower centre of gravity can also be achieved by adding tungsten skid plates, which also protect the lower parts of the chassis, especially important in F1, where a ride-height monitoring plank is used.
Due to its very high density, our tungsten heavy alloy is an ideal material for suppressing vibration in static or moving components. Applications for our tungsten heavy alloy include:
Crankshafts, pistons and gear levers in high performance cars; Turbine blades; Flywheels.
Wheel weights often fall off automobile wheels, leading to lead contamination of the environment.
There is a thriving market in lead-free wheel weights. European and Japanese automobile manufacturers have already switched to lead-free wheel weights and U.S. automobile manufacturers are currently in the process of making the switch. Asian auto manufacturers now primarily use tungsten alloy weights. Tungsten alloy weights are used widely in Europe, and US auto manufacturers are using tungsten alloy weights for automobiles destined for export to Europe.
Tungsten heavy alloy is becoming more and more popular for counterweight, balance weights for flywheels, ballast for F1 formula car, racing weights, dynamic balancing, etc. It is the best material of tungsten alloy for the balancing weight, and has been widely known and applied.
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.
