The Latest Price of High Purity Molybdenum Crucible Price in Early September 2024

The latest price of Φ32xΦ28x150mm high purity molybdenum crucible is USD150.00/PC, EXW XIAMEN, CHINA in the first half of September 2024.

Corrosion resistance, creep resistance and high temperature performance make molybdenum made crucibles very suitable for high temperature crystal growth processes. When sapphire is easy to extract, higher sapphire yield and quality can be achieved. The molybdenum-based crucible has heat resistance and a smooth surface, making it durable and cost-effective.

The surface roughness of the molybdenum crucible needs to be higher than 1.6 µm. When the surface of the crucible is rough, the sapphire is not easy to take out and it is easy to damage the crystal. In addition, the crucible will be damaged in the process. Chinatungsten Online's ultra-smooth crucible eliminates these problems. Sapphire manufacturers can benefit from this product because it eliminates complex and expensive processes. In addition, the smooth surface is resistant to corrosion caused by aggressively molten sapphire. This function can extend the service life of reusable crucibles.

Moly crucibles for sapphire growth furnaces are available with a variety of dimensions including round, in numerous standard diameters and wall thicknesses. Custom configurations are available. In addition, many other components for these furnaces are also customized.

The Latest Price of Tungsten Filaments

The latest price of φ0.8mm tungsten filaments is USD 2.00/PC, EXW XIAMEN, CHINA.

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.

The Latest Price of Cerium Tungsten Electrode

The latest price of φ3.2x175mm cerium tungsten electrode is USD 2.00/PC, EXW XIAMEN, CHINA.

Cerium 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 cerium 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 may 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.

Latest Price of Tungsten Plate on July 7, 2022

The latest price of 560x95x3.5mm tungsten plate is 520.00 USD/PC on July 7, 2022, 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.

Latest Price of Lanthanated Tungsten Electrode (WL20) on July 7, 2022

The latest price of Ø2.4x175mm lanthanated tungsten electrode (WL20) is 1.10 USD/PC on July 7, 2022, 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.
