Tungsten Plate Price in Late February 2024

3.5x96x560mm tungsten plate price is 520.00 USD/PC in late February 2024, EXW XIAMEN, CHINA. 

Tungsten plates can be as thin as 0.01mm or as thick as 127mm, with widths typically ranging from 10mm to 800mm. They can be used in many different applications and is valued for its corrosion resistance, ability to withstand extremely high temperatures, and ability to create rigidity and hardness when combined with other metals in the alloy.

Tungsten is used in the aerospace, research, building materials and light bulb industries. It is the predominant metal in electric furnace heating elements, as well as in any assembly where high pressure/high temperature environments are expected. Plates made of tungsten are commonly used in furnace construction, but are also important for making parts for the electronics and semiconductor industries, and can be found in a variety of lighting, vacuum plating, electronic vacuums and shielding.

Lanthanated Tungsten Electrode Price in Late February 2024

Ø3.2x175mm lanthanated tungsten electrode price is 2.00 USD/PC in late February 2024, EXW XIAMEN, CHINA.

WL20 electrodes contain at least 1.7% to 2.2% lanthanum for excellent arc starting, low burnout rate, good arc stability and excellent re-ignition characteristics. They are ideal if you want to optimize your welding capabilities. They can work well on either AC or DC electrode negatives with tips, or they can be used with AC sine wave power supplies. The tungsten electrode adding with rare earth element lanthanum holds sharp tips well, which is an advantage for welding steel and stainless steel on DC or AC from square wave power sources.

E-Beam Tungsten Filament Price in Early March 2024

The latest price of φ0.8mm E-Beam tungsten filament is USD 2.00/PC, EXW XIAMEN, CHINA in the first half of March 2024. 

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.

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.

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.

2% Ceriated Tungsten Electrode Price in Early March 2024

The latest price of φ1.6x150mm ceriated tungsten electrode is USD0.50/PC, EXW XIAMEN, CHINA in the first half of March 2024. 

Ceriated tungsten electrode (WC20) is alloyed with about 2% cerium oxide. It is a non-radioactive, refractory or non-consumable metal electrode material, which is the preferred substitute for thorium tungsten electrodes. Regular diameter of the electrode is between 0.5mm and 12.0mm, and the length is 150mm and 175mm.

The addition of this small percentage of cerium oxide increases the electron emission qualities of the electrode which gives them a better starting characteristic and a higher current carrying capacity with no spitting. With the increase of cerium oxide content, the ablation resistance and arc starting of ceriated tungsten electrode will increase; with the increase of use time, the welding performance will gradually decrease.

The electrode has excellent arc starting properties at low current, and can operate successfully with AC or DC electrode negative. If used on higher current applications, the cerium oxide March be concentrated to the excessively hot tip of the electrode. In addition, WC20 is also used in inert gas shielded arc welding, hydrogen atom welding, argon arc surfacing, pulse argon arc welding, plasma welding, plasma cutting, plasma spraying, plasma melting, etc. The welding materials can be carbon steel, stainless steel, silicon copper, copper, bronze, titanium and so on.
