China Tungsten Heavy Alloy Rod Plate Shielding High Density Alloy

Tungsten 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.
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
