Heavy Tungsten Alloys (HTA) is a class of metal materials made of high-density tungsten (W), usually with a mass fraction of tungsten of 90% to 98%, and add a small amount of other metals, such as nickel (Ni), iron (Fe), copper (Cu), cobalt (Co) and so on, to form tungsten-based alloys. These alloys are widely used in various fields because of their high density, high strength and excellent mechanical properties.
Heavy tungsten alloy features
1. High Density: The density of heavy tungsten alloys is very high, usually between 16-19 g/cm³, close to that of pure tungsten. As a result, they are ideal for many applications requiring high density materials.
2. High Strength and Hardness: Heavy tungsten alloys have very high strength and hardness and are able to withstand very high stresses and impacts.
3. Good ductility and machinability: Although tungsten itself is very brittle, its ductility and machinability can be significantly improved by alloying, making it easier to machine and shape during the manufacturing process.
4. Good corrosion resistance: tungsten and its alloys have good corrosion resistance in most environments, especially at high temperatures and in corrosive media.
5. Good Thermal Conductivity: Tungsten alloys have good thermal conductivity, which makes them excellent in applications that require rapid heat dissipation.
6. Ray Shielding Properties: Due to their high density, heavy tungsten alloys are able to effectively shield against X-rays and gamma rays, and are commonly used in the field of radiation protection.
heavy tungsten alloy applications
1. Aerospace: Due to its high density and strength, heavy tungsten alloy is commonly used in aerospace field for balance hammers, counterweights, inertial mass elements, etc., which need to increase the mass in limited space.
2. Defense & Military: Heavy tungsten alloys are used in the manufacture of high-density munitions such as armor-piercing bullets, warheads, etc., which are capable of penetrating armor and other hard targets. In addition, they are commonly used in bulletproof plates and protective equipment.
3. MEDICAL EQUIPMENT: In the medical field, heavy tungsten alloys are used in the production of radiation shielding devices, shielding materials in radiation therapy equipment, and radioactive source containers for syringes.
4. Industrial Application: Heavy tungsten alloy is widely used in high temperature molds, cutting tools, electronic packaging materials and other industrial fields. It is suitable for use in extreme environments due to its excellent resistance to high temperature, wear and corrosion.
5. Sports equipment: Some high-end sports equipment, such as weight blocks for golf clubs, racing car weight blocks, etc., utilize the high-density properties of heavy tungsten alloy to improve performance.
Overall, due to its unique physical and mechanical properties and wide range of applications, heavy tungsten alloy has become an important material in many high-tech and demanding industries.
