Tungsten has the highest melting point of all pure metals, at 3422°C (6192°F).
This property sets it apart from other metals and makes it ideal for high-temperature applications.
What is the Melting Point of Tungsten Compared to Other Metals? 4 Key Insights
1. Comparison with Other Metals
Tungsten's melting point is significantly higher than that of other commonly known metals.
For instance, iron melts at approximately 1538°C (2798°F), copper at 1085°C (1985°F), and aluminum at just 660°C (1220°F).
The high melting point of tungsten is a critical factor that contributes to its use in extreme environments where other metals would melt or lose structural integrity.
2. Applications Due to High Melting Point
The high melting point of tungsten makes it suitable for various high-temperature applications.
It is used in the manufacture of filaments for light bulbs, as it can withstand the high temperatures required for efficient light production.
Additionally, tungsten is used in the hot zones of vacuum furnaces, where it maintains its properties even at temperatures exceeding 1650°C (3000°F).
This includes retaining its low vapor pressure and high tensile strength, which are crucial for maintaining the integrity of the furnace and the materials being processed.
3. Unique Properties of Tungsten
Besides its high melting point, tungsten exhibits several other properties that enhance its utility in industrial applications.
It has the lowest coefficient of thermal expansion of any pure metal, which means it does not expand much when heated, making it stable in high-temperature environments.
Tungsten also has high corrosion resistance, particularly against acids and molten metals, and excellent electrical conductivity.
These properties, combined with its high melting point, make tungsten a material of choice for many high-temperature and high-stress applications.
4. Powder Metallurgy and Alloy Formation
Tungsten is often processed using powder metallurgy, a method that is particularly suited for metals with extremely high melting points.
By mixing tungsten powder with other metals like nickel, the sintering temperature can be reduced significantly, making it easier to form alloys.
This process is crucial for creating tungsten alloys that are formable and have enhanced properties suitable for specific industrial uses.
