What are vibrators for mobile phones?
When your mobile phone vibrates, there is an eccentric motion, which is caused by an eccentric motor with vibrating components. As the center of the gravity is eccentric, and is not in the rotor of the motor, then the mobile phone vibrates. In this case, you need machinery with high specific gravity and heavy wear-resistance, which tungsten provides.
Applications for tungsten heavy alloy in vibrators
Tungsten heavy alloy is an excellent material for making these components. Since the density of tungsten alloy is so high with a maximum density that should be 18.6g/cm3), it is a popular for the component in mobile phone vibrators, the vibrating parts of a clock, etc.
Mobile phone bobs and clock vibration parts are one of our leading products. Compared with other materials, tungsten alloy vibrators bear the advantages of accurate weight, and non-magnetism. In particular, since a motorized weight usually produces the vibrations, lighter-weight phones may have weaker vibrating mechanisms.
Various types of vibrators or bobs made from WHA are available.
