From the tiny, precise tungsten weights in self-winding watches to the massive, perfectly-balanced rotors on an aircraft, the unique physical properties of tungsten weights and tungsten counterweights bring exceptional quality to a variety of applications.Tungsten weights and tungsten counterweights are currently adding value to:
•aircraft control surfaces •aircraft rotor blades •guidance platforms •balancing of fly wheels and turbines •vibration dampening governors •fuse masses weights for self-winding clocks and watches
The inherent density, low-thermal expansion and resistance to chipping and breakage mean that, regardless of your particular application, you can rely on tungsten weights and tungsten counterweights to be stable, precise and durable—even under the most extreme conditions.
Before, DU counterweights have been used primarily in wide-body aircraft on rudders, outboard ailerons (wing assembly), and outboard elevators (tail assembly). Counterweights come in a variety of weights and shapes, and numerous weights and shapes are used in some aircraft. The DU counterweight can range in weight from 0.23 to 77 kg. In many cases, tungsten alloy counterweights have replaced DU counterweights in aircraft. Since 1981, The Boeing Company has provided customers with tungsten replacement counterweights, and tungsten counterweights have been installed in new Boeing 747 aircraft. Tungsten equivalents have been sent as spares since 1981.
However, the number of aircraft that contain DU counterweights is decreasing. Rather than refurbishing the DU (during maintenance operations), tungsten counterweights are used as a replacement.
