Tungsten Alloy Mobile phone vibration transducer is an important component of the device. When the phone vibrates, due to the effect of the eccentricity of the motor will produce eccentric movement, and shift the center of gravity is not the role of the motor rotor, which makes the phone can vibrate.

Phone vibrating action principle, require the mechanical parts need to have good wear resistance and high gravity characteristics. The density tungsten alloy reached 18.6g/cm3, which it has the same weight in smaller volume than other materials, and the phone vibrates required mechanical components have a large weight small volume. In this case, a tungsten alloy can fully play its good high-density characteristics. Compared with other materials, with the weight of tungsten alloy vibrator accurate, non-magnetic, high temperature, oxidation, corrosion resistance and other advantages.

Due to the high density tungsten alloy counterweight field it has a large mass, small features. This cutting-edge science in the aerospace field, tungsten alloy counterweight plays a major role. Among them, there are:

1: Turn on both sides of the counterweight tuo gyro rotor material. High density tungsten alloy makes the gyro rotor weight greatly increased, stable performance greatly improved, and can improve the static and dynamic balance on both sides of the steering rudder counterweight to enhance stability and control precision navigation and control of the entire system.

2: Aircraft engines and propellers dynamic components of the system. Tungsten alloy counterweight good stable performance, high-density, high-propellers are often designed as a failsafe control system mechanism. And functions to maintain a mass balance of the outer rotating member, thereby reducing or even eliminating the vibration propeller aircraft engines and dynamic elements of the system.
  
3: Flight control system telex. In the design of the flight control joystick scientific use of tungsten alloy counterweight to increase inertia, thereby improving ties between the elevator and ailerons.

High density tungsten alloy also known as high-density tungsten alloy, or heavy alloys. It is a tungsten-based material, a small amount of nickel, copper, iron, cobalt, molybdenum, chromium and other metallic binders, wherein the amount of tungsten alloy composed of 85% to 99%. Because of its heavy, small size and other characteristics, so in the counterweight and the weight distribution areas popular.

In reality, the more commonly used mainly high density tungsten alloy W-Ni-Cu and W-Ni-Fe, which has a high density, high strength, high hardness, and have good ductility and thermal conductivity, and is a excellent weight member. Tungsten alloy counterweight toxic pollution, compliance with international environmental standards. With a high proportion (> 18g/cm3), features high tensile strength and hardness, while tungsten alloy easy processing, availability and high availability, and thus in the defense industry, aerospace industry, medical industry, electrical industry, etc. extensive industry applications.

The main protection methods includes the time protection, distance protection and shielding, time protection is to minimize the contact time with the rays, for the point guard is to try to increase the distance of the body and the radiation source, and the point of shielding is placing a shield can effectively absorb rays between the radiation source and the human body.

The early shielding material for the X-ray shielding is the lead plate, concrete wall or barium, but because of the shielding performance and environmental consideration, tungsten alloy shield is popular used now.

If CT attenuation value and the rate is higher, The better the shielding performance of material to X-ray. As the density increase, the CT value of composite materials is also increasing. This is because the tungsten is a major component for X-ray shielding, and its content directly affects the shielding effect. The CT value of the composite material with 11.0g/cm3 density reaches 17,500, close to the CT value of the lead, it is indicating that the tungsten nylon composite material can be used as shielding for X-ray shielding. Further, the attenuation rate of tungsten nylon shielding to X-ray increases with the density. When the density reaches 11.0g/cm3, the attenuation rate is 97%, and the attenuation rate to X-ray remains stable.

The impact properties of Tungsten metal to tungsten nylon shielding as follows:

1. When receiving impact load, tungsten metal particles distributed within the collective nylon may cause crack deflection, suppressing tungsten nylon shielding composite fracture, and then improve the impact strength;

2. As there is a interface between the tungsten metal particles and nylon matrix, the gap at the interface can be used as a crack source, to reduce the impact strength. For the high density tungsten nylon shielding, tungsten metal particles play a major role in reducing the impact.

As the density increases, the impact strength of tungsten nylon shielding material successively reduced, but when low density, the moderate amplitude of impact strength is low. When the density is 8.8-11.0g/cm3, the data increases linearly, this is because with the increase of the content of tungsten particles, the voids at the interface also increases linearly, and the impact strength of the composite material with 11.8g/cm3 density decline larger, which is due to high levels of tungsten powder, can not fully wrapped nylon collective particles, the voids at the interface is bigger, so that impact strength has a sharp decline. In the whole, the impact strength of the 11.0g/cm3 density composite has a smaller decline in the acceptable range.
