What is Tungsten Filaments?

Tungsten filaments, also called cathodes or electron emitters or electron sources, are mainly made of high-quality tungsten. Of all pure metals, tungsten has the highest melting point (3422°C), the lowest vapor pressure at temperatures above 1650°C, and the highest tensile strength. Tungsten also has the lowest coefficient of thermal expansion of all pure metals. This combination of properties makes tungsten an ideal material.

Why Tungsten Filaments Are Used in Electron Gun?

Tungsten can be used in both thermionic electron guns and field-emission (CFE) electron guns. Electron beams come from filaments made of various materials. The most common is the tungsten hairpin gun, which is widely used in scanning electron microscopes, transmission electron microscopes, and microprobe systems. This filament is a tungsten ring that acts as a cathode. Apply voltage to the loop to heat it up. The anode, which is positive relative to the filament, forms a strong attraction to electrons. This causes electrons to be accelerated towards the anode. Some accelerate near the anode and down the column to the sample.

Why Are Tungsten Filaments in the Electron Gun Folded?

An electron gun works at a high temperature, which is required for thermionic emission. For this, a filament or the cathode should be of a material that has a high melting point in order for it to continuously emit electrons. Tungsten filament is folded with various shapes to help in focusing the electron beam.

What is Yttrium Tungsten Electrode?

Yttrium is a lanthanide metal found in most rare earth minerals, especially yttrium tantalite. It can be used as the yttrium phosphor to produce the red color on television screens and monitors and used as a superconductor and as a component of X-ray filters and superalloys. When added to tungsten as a rare earth element, it can be used as a welding electrode.

Among the non-consumable electrodes, the yttrium tungsten electrode is the most consistent, so it is often used to weld steel structures and non-ferrous alloys such as carbon steel, low alloy steel, copper, titanium, stainless steel, etc. under direct current/DC. This type of electrode arc beam is slender and has a large degree of compression, and its penetration is the largest in medium and large currents. Thanks to these characteristics, it is especially popular in the military industry and aerospace industry.

Yttrium tungsten welding electrode contains 1.8-2.2% yttrium oxide, and the electron escape work is 2.8-3.2ev. They are marked WY-20 (navy blue) according to international marking. Among the components of the WY20 electrode, there are silicon, molybdenum, manganese, sulfur, carbon, and phosphorus. When the impact hardness is 100 J/cm2, the surfacing coefficient is 9.5 h/Ah. One of the characteristics of domestic electrodes is the need for short arc processing and pre-baking. The last is done in a dedicated furnace for an hour.

What is Tungsten Copper Alloy?

Tungsten-copper alloys are pseudo-alloys of copper and the refractory metal tungsten. Since copper and tungsten are immiscible, the material consists of different particles of one metal dispersed in a matrix of another metal. As a result, the microstructure is a metal matrix composite rather than a true alloy.

Characteristics of Tungsten Copper Alloy

It combines the properties of two metals to form a material that is heat, ablation resistant, highly thermally and electrically conductive, and easy to process. It is also resistant to arc corrosion, mechanical wear and contact welding. Parts are made from tungsten copper alloy by pressing tungsten particles into the desired shape, sintering the compacted part, and finally infiltrating it with molten copper.

Tungsten Copper Alloy Grades

Common grades of this alloy contain 5% copper to 50% copper with tungsten in balance. The typical properties of an alloy depend on its composition. Alloys with less copper have higher density, higher hardness, and higher resistivity. Typical densities are 17.3 g/cm3 for WCu10 alloy and 12.2 g/cm3 for WCu50 alloy. WCu10 alloy has higher hardness and resistivity than WCu50 alloy of 260 HB kgf/mm2 and 6.5 µΩ.cm.

Tungsten Copper Alloy Applications

Tungsten copper products are meeting the increasing demands of high-tech applications, such as major electronic equipment, safety equipment, aviation and power generation, etc. Sheets and plates made from copper-tungsten alloys are used in many industries, including aerospace and power generation. Heat exchanger and cooler elements in electronic equipment as well as passive heat sinks, arches and vacuum contactors in high current equipment are made of this alloy.
