PURE TUNGSTEN

About PURE TUNGSTEN

• Highest Melting Point: Tungsten has the highest melting point of all metals at approximately 3,422 C (6,192 F), making it indispensable for applications requiring thermal stability in extreme heat.
• High Density: It is an extremely dense metal, with a density of around 19.3 g/cm, comparable to gold and uranium. This property makes it ideal for applications needing high mass in a small volume, such as weights and radiation shielding.
• Exceptional Strength and Hardness: It is one of the strongest metals at room temperature and retains its mechanical properties at high temperatures. Tungsten's carbide form is nearly as hard as diamond.
• Low Thermal Expansion: Tungsten has the lowest coefficient of thermal expansion of any pure metal, a property that makes it useful for glass-to-metal seals.
• Good Electrical and Thermal Conductivity: It possesses good thermal and electrical conductivity (about one-third of copper), making it valuable for use in electronics and heating elements.
• Corrosion Resistance: Chemically, tungsten is relatively inert at room temperature and exhibits excellent resistance to most mineral acids and corrosion, although it can oxidize at elevated temperatures.
• Brittleness (under standard conditions): While pure single-crystalline tungsten can be ductile, polycrystalline tungsten is intrinsically a brittle and hard material under standard conditions, which can pose challenges for certain fabrication processes.
• Low Vapor Pressure: It has the lowest vapor pressure of all metals at high temperatures.
• Non-Magnetic: Pure tungsten is considered paramagnetic, meaning it is only weakly attracted to magnetic fields and does not retain magnetism, a useful property in sensitive electronic and medical applications. 

• Lighting: Filaments for incandescent light bulbs and halogen lamps.
• Electronics: Electrical contacts, electrodes, and components in integrated circuits and vacuum tubes.
• High-Temperature Applications: Components for high-temperature furnaces, rocket nozzles, and fusion reactors.
• Medical Technology: Radiation shielding for X-ray and CT scanning equipment.
• Tooling and Defense: Tungsten carbide is used for cutting tools, drill bits, and armor-piercing projectiles.
• Weights and Counterbalances: Used in aircraft and race cars due to its high density.
