Heavy Tungsten Alloy Description

High density alloy
Tungsten Alloy Code: GMW
Density: (17-18.5) g/cm3
Main Component: W(88-98)% with the addition of nickel and copper or nickel and iron, etc.

Main Application:
1- Shakers in micromotor widely used in toys and mobile phones.
2- Radioshielding materials. For example, collimator in flaw detector and clinical Radioshielding needle.
3- Parts of balance wight
4- Widely used in military equipment and fishing equipment to raplace uranium and plumbum for no pollution in circumstance.
5- Used in electro-forge and electro-heading.
6- Used in armor-piercer.
7- Contacts material in high voltage.
8- Inertia balance weight ball in missile, plane and race-car.

Tungsten Heavy Alloy Advantages:
- High density
- Excellent mechanical properties such as high vibration-damping capacity and high Young's modulus.
- Excellent radiation-shielding property
- High thermal conductivity with low thermal expansion coefficient
- Higher high-temperature strength and thermal shock resistance
- High oxidation resistance and corrosion resistance

**We supply this material as per customerized sizes and properties.
