Tungsten Alloy Mobile Phone Vibrator
January 26, 2024

Tungsten alloy mobile phone vibrator is an important part of mobile phone vibration device, and compared with other materials, tungsten alloy has significant advantages in density, hardness, wear resistance and other aspects. When the phone vibrates, there is an eccentric motion, which is caused by the eccentric motors in the vibrating parts. Because the center of gravity is shifted, rather than in the motor rotor, the phone begins to vibrate. In this way, mechanical parts with good wear resistance and high gravity are needed.

Tungsten Alloy Vibrator Used in Clocks
January 19, 2024

Tungsten alloy oscillator plays a key role in the clock, it is a device used to produce stable oscillations. Tungsten alloy is a metallic material with high density and high strength. This oscillator can swing inside the clock to provide a stable time base signal by oscillating.

What Is Tungsten Carbide Balls?
January 12, 2024

Cemented Carbide Balls, also known as Tungsten Carbide Balls, are a type of spherical product made of cemented carbide material. Cemented Carbide is a kind of alloy with tungsten carbide, cobalt and other elements as the main components, which has extremely high hardness, wear resistance and corrosion resistance. Therefore, Cemented Carbide Balls are widely used in a variety of occasions that require high precision and high wear resistance.

Introduction of Carbide Saw Blade Tips
