What is Tungsten Heavy Alloy?

Tungsten heavy alloys generally are refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added with Co、 Mo、Cr, etc. They have very high melting point and have a density twice that of steel and are more
than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 18.75 g/m3). Nickel, iron and copper serve as a binder matrix, which holds the brittle tungsten grains together and which makes the alloys ductile and easy to machine. Nickel-iron is the most popular additive, in a ratio of 7Ni:3Fe or 8Ni:2Fe (weight ratio). The conventional processing route for tungsten heavy alloys includes mixing the desired amount of elemental powders, followed by cold pressing and liquid phase sintering to demanded density. The matrix alloy melts and takes some tungsten into solution during liquid phase processing, resulting in a microstructure through which large tungsten grains (20–60µm) are dispersed in the matrix alloy. The as-sintered material often is subjected to thermo mechanical processing by swaging and aging, which results in increased strength and hardness in the heavy alloys.

Product Description

Product Description

Main properties of tungsten heavy alloy

1. High density: Tungsten heavy alloy has a density of 17.0-18.5 g/cm³, which is much higher than other metals like steel, copper, and brass.

2. High strength: Tungsten heavy alloy has a high strength-to-weight ratio, making it ideal for applications that require high strength and durability.

3. Corrosion resistance: Tungsten heavy alloy is highly resistant to corrosion, making it suitable for use in harsh environments.

4. High melting point: Tungsten heavy alloy has a very high melting point of 3410°C, making it ideal for use in high-temperature applications.

5. Non-toxic: Tungsten heavy alloy is non-toxic and does not pose any health risks, making it suitable for use in medical and dental applications.

6. Machinability: Tungsten heavy alloy is easy to machine and can be shaped into a variety of forms and sizes.

7. Radiation shielding: Tungsten heavy alloy is an excellent material for radiation shielding due to its high density and ability to absorb radiation.

Main application of Tungsten Heavy Alloy

Tungsten Heavy Alloy (WHA) is a high-density material that is used in a variety of applications where weight is a critical factor. Some of the main applications of WHA include:

1. Defense and Aerospace: WHA is used in the production of armor-piercing projectiles, kinetic energy penetrators, and other high-density components for military and aerospace applications.

2. Radiation Shielding: WHA is used as a radiation shielding material in medical and industrial applications.

3. Sports Equipment: WHA is used in the production of golf club heads, fishing weights, and other sporting equipment where weight is a critical factor.

4. Automotive Industry: WHA is used in the production of crankshaft counterweights, balance weights, and other high-density components in the automotive industry.

5. Oil and Gas Industry: WHA is used in the production of drilling tools and other components in the oil and gas industry where high-density materials are required.

Overall, WHA is a versatile material that finds applications in a wide range of industries where high-density materials are required.
