Tungsten pin

Tungsten pin

Tungsten pin is pin made of the material—tungsten. Since it is made of tungsten, tungsten pin owns the properties of high melting point, high corrosion resistance, tensile strength and low coefficient of thermal expansion. When added steel or other element, its hardability would be improved. 

The surface condition of tungsten pin is smooth and bright. Moreover, no stain, dirt, oxides, drawing tracks, scratches and damages are admitted on the surface of tungsten pin.
  

Tungsten Needle

Tungsten Needle

Tungsten needle is widely used in the construction of furnace tooling and parts and as a feedstock for the fabrication of parts for the electronics and semiconductor industries. Surface can be supplied in a shiny or matte; dependent upon the thickness and width parameters. 

Tungsten needles grown from hexacarbonyl tungsten vapors in a glow-discharge condition are described. The needle growth occurs on a tungsten substrate in a temperature range from nearly room temperature to 1500 °K, but needles produced below and above ~1100 °K are quite different in morphology and crystalline state. The products at lower temperatures are tungsten particles agglomerated in dendrite like shapes while those at higher temperatures possibly are whiskers.
   

Tungsten ball

Tungsten ball

tungsten ball for RC-cars

Tungsten ball is the general term for pure tungsten ball, tungsten alloy ball and tungsten carbide ball. 

Pure tungsten ball is used the material of pure tungsten whose density is over 19.2g/cm3, and it is the highest density among tungsten balls. Another reason for applicator using pure tungsten ball is that tungsten ball has the highest melting point.


Tungsten alloy ball is tungsten ball alloy with Ni and Fe, or other metal element to improve other properties of tungsten, such as to make unbrittle and easy to be processed. Tungsten alloy ball can be marked words on the ball, but pure tungsten ball has no such properties.
     

Tungsten point/contact

Tungsten point/contact

Tungsten point/contacts are for use in high voltage applications, usually where highly repetitive switching is required. Tungsten has a melting temperature of 3,380℃ which gives it excellent arc-erosion resistance. Tungsten may develop troublesome oxide films, especially when used as the anode contact in some DC applications. Therefore, tungsten is often used as the cathode contact, and a palladium alloy used as the anode contact. Such a combination also minimizes contact interface resistance and material transfer.
   

Tungsten electrode

Tungsten electrode

Tungsten electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.

By special processing, produce hot-rolling and cold-rolling products with high quality tungsten slabs, such as tungsten electrode plate, heater, heat-shield and tungsten boats etc, which are used in electronics, electronic-vacuum and illumination etc. 

Tungsten plate

Tungsten plate

Tungsten plate is widely used in the construction of furnace tooling and parts and as a feedstock for the fabrication of parts for the electronics and semiconductor industries. Surface can be supplied in a shiny or matte; dependent upon thickness and width parameters. 

Tungsten Boat

Tungsten Boat

As a special and effective boat vessel, tungsten boat is widely used in metallizing, electron-beam spraying as well as the heat process with sintering and annealing in vacuum coating industries. 

Tungsten boats sources are used for the vacuum evaporation of materials that are in granular or pellet form. They can also be used to evaporate small lengths of wire or to evaporate materials which would not properly "wet" the surface of an evaporation filament. These boats are ideal for use in small evaporation systems, such as bell jars, for experimental and prototype work.

Tungsten wire mesh heater

Hot-zone designing and technology is including materials and fabrication methods for heating elements, shields and retorts. Temperature is important. Furnace temperatures, including operating temperature, maximum temperature, temperature ramp-up rate(s) and thermal uniformity, are essential to arrive at the optimum furnace design. Operating temperature affects heating element, shield and retort materials of construction, and power requirements and control-system design.

Tungsten heater filament, single or multiple strand tungsten, molybdenum, or tantalum wire. Stranded wire can incorporate a core of aluminum for wetting purposes.

Tungsten heater materials

Tungsten heater materials

The most important heater material is tungsten. In tungsten's natural formis usually obtained from the minerals wolframite (Fe, Mn) WO4 and schoelite (CaWO4). Because 70% of our original tungsten resources have been depleted, methods have been found for purifying relatively poor-grade ores. 

The quality of tungsten heater wire depends upon many factors, and the materials and manufacturing process are carefully controlled. The powder used to produce the ductile metal is initially of high purity. For the purposes of inhibiting grain growth, however, very small quantities of partly volatile alkali silicates and non-volatile oxides such as silica, alumina, thoria, or calcia are added to the tungsten powder.
  

Application of Tungsten Heater

Application of Tungsten Heater

Tungsten heaters can be stranded into single or multi wires according to the samples or drawings of customers. Pure wire and doped wire are both available. Diameter of tungsten wire: 0.2-1.2mm.

The main application of tungsten heater are as follows:  

1) Vacuum metalized applicant 

2) Aluminum spraying, ceramic coating, metal, plastic 

3) For aluminizing of chromo-scope & kinescope 

4) For mirror making 

5) For Automobile Head Lamp Reflector 

6) Compact Disc Aluminizing 

7) For dispenser type cathodes 

In response to the increasing demand for heaters to be used in conjunction with dispenser cathodes. The majority of heaters are fabricated to customer prints. 

8) For oscillight and conjunction of microprocessor chip.
