Tungsten Nut 855

Tungsten nut is a type of fastener with a threaded hole. And it is almost always used in conjunction with a mating bolt to fasten multiple parts together. In general, the nut and bolt are made of the same material. In other words, the tungsten nut is matched with tungsten bolt. The two partners are kept together by a combination of their threads’ friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to…

Tungsten Bolt 733

Tungsten bolt, the combination of the head and threaded rod, is a form of threaded fastener with an external male thread. Usually, it is used with tungsten nut. Tungsten bolt has high temperature resistance so that it is a very important bolt for high temperature furnace, sintering furnace and other high-temperature environments. It has different standards, such as American, British, and so on. The choosing of the standard should be in accordance with their match machines. Tungsten bolt is widely…

Tungsten Cathode 703

Tungsten cathode may be divided into pure tungsten cathode, potassium tungsten cathode, tungsten-tungsten oxide cathode, WC-ThO2 cathode, and multiple composite rare earth oxide cathode, etc. Pure tungsten cathode does not add any oxide with low thermal electron emission efficiency so that it is little used in vacuum devices. The producing process of this type of cathode material is simple, so, it cost less. While the arc starting performance and ablation resistance performance of the tungsten cathode are relatively poor. Therefore,…

Product
Tungsten Anode 688

Tungsten anode has the advantages of high melting point and excellent electron emission performance so that it can be used as the electrode material in arc lamp, such as anode of xenon lamp for movie projection. Initially, the effect of tungsten anode in xenon lamp was not idea with short service life. After using a period of time, it began to darken and its brightness was greatly reduced. This was because the processing of tungsten anode at that time was…

Product
Tungsten Needle 737

Tungsten needle can be produced using tungsten wire with the diameter of 1mm as raw material. The tip of tungsten needle can be processed into needle or spade shape depending on the shape of the broken end of tungsten wire. Besides, the depth of tungsten wire tip immersed in electrolyte can be adjusted at any time to slow down the tip slope, and therefore, it can be processed into cone shape. Tungsten needle with high hardness can be used to…

Product
Ground Tungsten Rod 680

Ground tungsten rod is a type of tungsten rod, whose surface is ground. The tungsten rod of ground surface has the characteristics of uniform internal structure, fine grain size, good wear resistance, high hardness, high melting point, high density, high temperature resistance, good processing performance, no surface cracks, no burrs and no obvious oxidation phenomenon. Therefore, it can be used to manufacture tungsten wire, tungsten cathode, tungsten anode, tungsten electrode, outgoing line and bracket. Grounding process can be carried out…

Product
Spot Welding Tungsten Rod 665

Spot welding tungsten rod means the tungsten rod is specifically designed for spot welding. As the electrode of spot welding machine, tungsten rod has the characteristics of good high-temperature strength, excellent creep resistance, nice heat conduction, electrical conductivity and electron emission performance, thereby it can improve the temperature of the welding spot and avoid cold solder joint, and therefore, it improves the welding quality, reduces the defective rate. In the traditional spot welding machine, copper rod is used as the…

Product
Tungsten Rod 640

Tungsten rod can be sintered tungsten rod or forged tungsten rod, whose surface may be ground. Forging and Annealing Test on Pure tungsten bar Sample Preparation Raw material: Pure tungsten powder with particle size of 2.01μm. The Ф50mm tungsten rods were obtained by isostatic pressing and intermediate frequency sintering. Then, these samples were forged and drawn to obtain the tungsten rods with diameter of 23mm. According to the difference in the average forging ratio, three types of forging processes were…

Product
Forged Tungsten Bar 629

Forged tungsten bar means the tungsten bar is produced by forging and rolling with refined metal crystal grains. The fiber is continuous as it is pressed repeatedly. This type of tungsten bar can be applied as the tool bit of lathe tool, tungsten wire for lighting equipment and various thermal conductors. “Forging & Rolling” is the combined processing method that uses the forging and rolling machine to put pressure on the metal blank to generate plastic deformation to obtain the…

Product
Sintered Tungsten Bar 643

Sintered tungsten bar may be produced by indirect-heated way to sinter under uniform temperature conditions using medium-frequency induction sintering furnace as an important piece of producing equipment. Compared with vertical sintering method, the quality of tungsten bar prepared by indirect sintering method is improved with excellent energy-saving effect. And this type of tungsten bar can be used for the preparation of tungsten wire. Medium-frequency induction sintering furnace adopts tungsten tube as heating element, and zirconium oxide as insulation material. The…
