99.95% Pure Tungsten Heating Elements For Sapphire Industry
1,Description:
Tungsten heating elements are heating components made from tungsten, a refractory metal known for its high melting point and excellent electrical resistance. These heating elements are widely used in high-temperature applications that require efficient and reliable heating, such as furnaces, vacuum systems, and semiconductor manufacturing.
Tungsten heating elements exhibit exceptional resistance to high temperatures and can operate at temperatures above 2,600°C (4,700°F) without significant degradation. They have a high melting point of 3,422°C (6,192°F), which allows them to withstand extreme heat without melting or warping. This makes them ideal for applications that involve rapid heating or prolonged exposure to high temperatures.
