Tungsten rods are known for their exceptional physical and chemical properties, making them suitable for various demanding applications. Here are the key properties:
Physical Properties:
Density:
Tungsten has a very high density of approximately 19.3 g/cm³, making it one of the densest elements.
Melting Point:
Tungsten has the highest melting point of all metals, at around 3422°C (6192°F).
Boiling Point:
Tungsten’s boiling point is about 5555°C (10031°F).
Hardness:
Tungsten is extremely hard and durable, with a hardness on the Mohs scale of about 7.5.
Tensile Strength:
Tungsten rods have a high tensile strength, which makes them resistant to deformation under stress. The tensile strength of tungsten is approximately 1510 MPa.
Electrical Conductivity:
Tungsten has good electrical conductivity, although it is not as conductive as copper or silver.
Thermal Conductivity:
Tungsten has high thermal conductivity, allowing it to efficiently transfer heat.
Coefficient of Thermal Expansion:
Tungsten has a low coefficient of thermal expansion, meaning it expands very little when heated.
Chemical Properties:
Corrosion Resistance:
Tungsten is resistant to corrosion and oxidation, particularly at high temperatures.
Reactivity:
Tungsten is chemically inert and does not react easily with other elements. It remains stable in air at room temperature but can oxidize at higher temperatures.
Chemical Stability:
Tungsten is highly stable and does not easily react with acids, bases, or other chemicals under normal conditions.
Oxidation:
At high temperatures, tungsten can form oxides, which can affect its properties. However, it remains relatively stable compared to other metals.
Summary:
Density: ~19.3 g/cm³
Melting Point: 3422°C (6192°F)
Boiling Point: 5555°C (10031°F)
Hardness (Mohs): ~7.5
Tensile Strength: ~1510 MPa
Electrical Conductivity: Good
Thermal Conductivity: High
Coefficient of Thermal Expansion: Low
Corrosion Resistance: High
Reactivity: Chemically inert
