Tungsten Alloy Sphere for Counterweight

Tungsten alloy sphere counterweights are incorporated into the pitch control system of many propeller designs as a fail-safe device to prevent over speeding. What's more, tungsten heavy alloy is incorporated into the rotating flywheels of gyroscopic controls for the storage of kinetic energy. Tungsten alloy counterweights are used for adjusting the center of gravity of the triangle and the frequency of oscillation of the laser beams. Bucking bars made of tungsten heavy alloy are ideal for vibration-damping applications with high density.

Usually, space for the counterweight is limited, so the need of heavy but small objects is great. Tungsten alloy sphere, with the density of 16.5/ cm 3 to 18.5/m3 about 50 percent higher than lead and much higher than steel, is ideal for counterweight. Tungsten alloy counterweight as sphere can prolong the life of itself because of its wear resistance and round shape. In addition, lead is toxic while tungsten alloy sphere is environmentally friendly.
