1,Description:
Material: Tungsten boats are made from pure tungsten (W) metal.
Density: Tungsten has a high density, typically ranging from 19.1 to 19.3 grams per cubic centimeter (g/cm³).
Melting Point: Tungsten has an extremely high melting point of approximately 3,422 degrees Celsius (6,192 degrees Fahrenheit), making it suitable for high-temperature applications.
Thermal Conductivity: Tungsten exhibits excellent thermal conductivity, allowing efficient heat transfer within the boat.
Electrical Conductivity: Tungsten is a relatively poor electrical conductor compared to materials like copper or aluminum.
