Can tungsten tubes be bent or shaped easily?​

Pure tungsten is a hard and brittle material, so bending or shaping it at room temperature is extremely difficult. However, with specialized techniques such as hot forming (heating the tungsten tube to a high temperature where it becomes more malleable) and using appropriate tooling, it can be bent or shaped. Tungsten - alloy tubes, especially those with elements that enhance ductility like rhenium, are generally easier to form compared to pure tungsten tubes.​

Tungsten has a relatively high electrical conductivity, with a resistivity of about 5.65 μΩ·m at 27 °C. This property makes tungsten tubes useful in some electrical applications, such as in certain high - temperature electrical contacts or as components in electrical heating elements where both electrical conductivity and high - temperature resistance are required.​

Yes, tungsten tubes are highly resistant to radiation. Their high density and stable atomic structure allow them to effectively absorb and scatter various types of radiation, including gamma rays and neutrons. This makes them suitable for use in radiation - shielding applications in industries such as nuclear power, medical radiation treatment facilities, and some aerospace applications where exposure to cosmic radiation is a concern.​

First, ensure that the furnace is cooled down and isolated from power. Carefully align the tungsten tube in the designated location, which may involve using mounting brackets or fixtures. Make sure the connections, if any, are properly sealed to prevent gas leakage in gas - fired furnaces or to ensure good electrical contact if the tube is part of an electrical heating element. After installation, perform a thorough inspection to check for any misalignment or loose connections before restarting the furnace.
