Tungsten Point 327

Tungsten point, also known as tungsten contact, is often used as an electrical contact. It is for use in high voltage applications. Tungsten point is widely used in relays, which generally refers to a device that provides an electrical connection between two or more points in response to the application of a control signal. The user’s requirements for tungsten contact are shown as follows: 1. High hardness, good impact toughness; 2. No cracks and no scratches with smooth surface; 3.…

Tungsten Foil 302

Tungsten foil may be prepared by electropolishing in sulfuric acid-methanol for equation of state (EOS) target. The tungsten foil may be prepared with high surface quality (RMS roughness less than 50nm) and thickness uniformity beyond 99%, and may keep the density of raw materials so that this foil can satisfy the requirement of laser driven materials for the research of high temperature and pressure EOS. Thus, electropolishing is a significant method for preparing the foil which can fulfill the requirement…

Tungsten Sheet 294

Tungsten sheet is obtained by the following processes: Isostatic pressing and high-temperature sintering of tungsten powder to obtain tungsten blank; rolling the blank and then cutting it through a shearing machine to obtain tungsten sheet. In general, tungsten sheet with a thickness of less than 0.3mm is thin tungsten sheet. With the development of electric vacuum technology, thin tungsten sheet with a roughness of less than 0.2μm and in a mirror bright state is in great demand in recent years.…

Product
Tungsten Plate 315

Tungsten plate has a wide application and becomes more and more common seen with the rapid development of nuclear industry and aviation industry. While tungsten plate is easily layered and cracked during rolling process as tungsten has high melting point and high ductile-brittle transition temperature. And the grain size of tungsten is so coarse that it will reduce the mechanical properties of the tungsten plate product, and therefore affect the service life of the downstream tungsten product. So, it has…

High-purity Tungsten Granule 600

High-purity tungsten granule may be used as a fluxing agent for the determination of carbon and sulfur in metallic manganese by high-frequency combustion IR absorption spectrometric method. This method has the advantages of high accuracy, easy operation, and simultaneous determination of C&S so that it has been widely applied in the quick determination of carbon and sulfur contents in steel alloys, minerals, and soil samples. There are three kinds of fluxes in determining carbon and sulfur content in metal manganese…

Tungsten Granule 599

Tungsten granule is a polyhedral particle with bright gray color, which may be applied as fluxing agent for determining carbon and sulfur in metals by infrared absorption method. Determining Carbon and Sulfur in Electrolytic Manganese Metal with Single Tungsten Granule 1. Main reagents and instrument flux: (1) 0.371mm (40 mesh) tungsten granule (C: 0.0006%, S: 0.0003%); Standard sample: YSBC 11139-2007 (C: 0.027%, S: 0.0126%); Standard sample: YSBC 18101-03 (C: 0.168%, S: 0.019%); CS-878A infrared carbon and sulfur analyzer; L-CS porcelain…

Product
Non-consumable Electrode 956

Non-consumable electrode can be applied in gas tungsten arc welding (GTAW), or tungsten inert-gas (TIG) welding. GTAW or TIG welding is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it requires significant operator skill and can only be accomplished at relatively low speeds. It can be…

Product
Barium Tungsten Electrode 731

Barium tungsten electrode may be manufactured via powder injection molding (PIM) process with homogeneous microstructure and good electron emission performance, which has been successfully applied in high power xenon flash lamps and pump lamps for laser. Compared with conventional tungsten electrode wound with tungsten wire, barium tungsten electrode for high pressure gas discharge lamps is produced using PIM process to form electrode with complex shapes, allowing designers to design electrode shape in accordance with the ding of electrode. PIM is…

Product
Tungsten Electrode Holder 580

Tungsten electrode holder is also called tungsten needle holder, tungsten rod clip or tungsten clip, which is applied to clamp electrode to avoid falling during welding. Generally speaking, the electrode holder is used in a jacket, flow guide or copper head. Tungsten electrode holder is divided into two parts, clamp and jacket, both of which are made of tungsten. They can be applied in combination. Also, clamp can be used alone. The specification of tungsten electrode holder should be matched…

Product
Ternary Composite Tungsten Electrode 665

Ternary composite tungsten electrode should be studied to know its lamination mechanism during sintering. A tertiary RE-W electrode with a diameter of 16mm was used to do the research. The morphologies and phases of the sintered billets were investigated by SEM and XRD, respectively. The composition of the second phase particles was analyzed by EDAX. The percentages of rare earth oxides in different regions were detected by ICEP-AES. The distribution of RE elements at the fracture was detected by EPMA.…
