Tungsten alloy, with its comprehensive advantages in density, temperature resistance, and mechanical properties, serves as a bridge connecting traditional industry with high-end manufacturing. From aerospace to medical electronics, from defense security to new energy development, tungsten alloy is continuously expanding its application boundaries through innovations in materials science. The characteristics of tungsten alloy bars include high density, high melting point, high strength, good toughness, and more.
High Density: The density of tungsten alloy bars typically ranges from 16.5 to 18.75 g/cm3, more than double that of steel. This property gives it a significant advantage in scenarios requiring high weight within limited volumes. For example, in the aerospace sector, tungsten alloy is used as counterweights in spacecraft to adjust the center of gravity, enhancing flight stability. In the medical field, the high density of tungsten alloy bars makes them an ideal material for X-ray collimators, efficiently focusing radiation beams and reducing damage to healthy tissues.
High Melting Point: The high melting point of tungsten alloy bars enables excellent performance in high-temperature industrial environments. In the nuclear industry, its heat resistance makes it a key material for reactor shielding layers, effectively blocking neutron and gamma ray flows. Additionally, the low coefficient of linear expansion ensures good dimensional stability during drastic temperature changes, making it suitable for precision instrument manufacturing.
High Strength and Good Toughness: Tungsten alloy bars exhibit high strength and good toughness, with a tensile strength of 900-1,100 MPa and an elongation of 6%-29%.
Excellent Radiation Shielding Performance: The high atomic number and density of tungsten enable tungsten alloy bars to absorb X-rays and gamma rays more effectively than lead, without the toxicity issues associated with lead. This makes them widely used in medical and nuclear industries.
Electrical and Thermal Conductivity: Tungsten-copper alloy bars, a type of tungsten alloy bar, offer good electrical conductivity while maintaining high strength, making them a preferred choice for high-voltage electrical contacts and electronic packaging materials.
Corrosion Resistance: In the petrochemical industry, tungsten alloy bars can withstand corrosive media such as H?S and CO?, offering a longer service life compared to stainless steel.
