What are the different types of tungsten wire?

tungsten wire may vary according to its size, use and appearance. The most common application of this wire is for lighting lamps because tungsten is very tolerant to heat. Halogen, fluorescent and bulb lights use the thinnest type, usually with a diameter of 0.001 inches (0.254 millimeters) to 0.1 inches (2.54 millimeters). The type 1a wire has unlocked properties, they are usually used in hospital equipment such as Leep electrodes, thermionic emitters and generations of corona. Type 1b can be used for products that use glass seals to metalboard such as vacuum tubes, reed switches and bulbs; These wires are usually a clean 99.95 percent and are excellent heat and electric wires. Pure tungsten wires are usually more than 0.20 inches (5.08 millimeters) on average. They are so resistant to heat that some tungsten wires can have a melting point of about 6 150 ° Fahrenheit (3,400 ° Celsius). This means that some elements have been added to somehow modify their strength and resistance.Doping also changes its chemical structure and wire will have a blocking composition that makes it more reinforced. Three elements are commonly used in tungsten doping: potassium, aluminum and silicon. This type of wire ranges from 0.001 inches (0.254 millimeters) to 0.350 inches (6.35 millimeters) in thickness and is used for wire and lamp fibers.

Another chemical called Thoria can also be mixed with tungsten to create a specialized wire. Type 2a is a thiorized filament wire with just 1 percent Thoria, while type 2B has 2 percent. These wires can be made in a thin fiber and used for microwave furnaces and plasma control. This type of tungsten wire is allegedly more efficient as an electric conductor.

The

tungsten wire can also be mixed with another element called Rhenium. Wolfram and Rhenium can effectively create effective metal alloys because both have very high melting points 6 192 ° F (3 422 ° C) and 5 767 ° F (3 186 ° C). This type of wire is used when very high heat is required, for example in thermo -boiling. Wolfram-Rhenium wires are categorized on the basis of a percentage involving Rhenia. The WR30 has 3 percent Rhenium, the WR200 has 20 percent, while the WR250 has 25 percent. All these types are highly durable, strong and corrosion resistant.

Other elements used to produce alloy conductors are molybdenum because it also has a high melting point of 4 753 ° F (2,623 ° C). Both molybdenum and tungsten have very similar chemical properties that make them ideal for alloying. This type of tungsten wire can be used in furnaces, cars and even aircraft, as it is also resistant to heat and corrosion.
