1,Description:
Material: Tungsten (W) is the primary material used in tungsten heating elements.
Melting Point: Tungsten has one of the highest melting points of all elements, approximately 3,422 degrees Celsius (6,192 degrees Fahrenheit). This high melting point allows tungsten heating elements to withstand extremely high temperatures.
Resistance to Oxidation: Tungsten exhibits excellent resistance to oxidation at high temperatures, allowing tungsten heating elements to maintain their structural integrity and performance in demanding environments.
Electrical Conductivity: Tungsten is a good conductor of electricity, enabling efficient energy transfer and heat generation in tungsten heating elements.
Thermal Conductivity: Tungsten possesses relatively low thermal conductivity compared to other metals. This property allows tungsten heating elements to generate and retain heat efficiently within the element itself.
