High-Performance Tungsten Rhenium Alloy Project To Promote the Application Range of Conditions and prospects and Problems and Improvements

Tungsten -3 rhenium tungsten rhenium alloy wire is mainly used for the electron gun , TCD filament , packaging and testing probe card, the alloying element rhenium uniformity and processing difficulty, products are mostly dependent on imports , the project by improving the level of technology and equipment level , successfully prepared tungsten rhenium alloy wire , and to achieve mass production, downstream manufacturers to meet domestic requirements , to replace imported tungsten rhenium wire, mainly used in electronics technology, high-temperature alloy technology and aerospace technology and other aspects :

Tube material often subject to temperature changes and strong vibration , tube filament tungsten rhenium alloy wire used , a wide composition range . Requires high -performance anti- sagging filament , generally doped tungsten -3 rhenium tungsten rhenium alloy wire , requiring good low temperature ductility filament , usually tungsten -20 -25 rhenium tungsten rhenium and tungsten rhenium alloy wire. Satellite tubes require long life, high reliability , anti- vibration , launch satellites , tubes typically are exposed to 5-8G acceleration of gravity , -3 rhenium tungsten filament material requires tungsten rhenium alloy wire as the filament in order to meet the requirements.

Medical treatment machines and industrial inspection machines accelerated electron gun filament heated tungsten rhenium alloy wire must be used , while ensuring the performance requirements , to meet the long life requirements.

Folding pressure rectifier filament choose tungsten rhenium alloy wire production, not brittle , splitting fracture , rectifier electrical parameters of good consistency.
Tungsten- rhenium alloy is also used in the X-ray tube anode target target surface , the radiation effect, electron impact resistance performance is good , focal path loss, the focus is small, reducing the anode angle , the rotation is an excellent anode material. Tungsten- rhenium alloy target having a tungsten target both high penetration ability, and a molybdenum target and good color characteristics, in practice , the use of low voltage, for different thickness of the soft tissue , light metals and nonmetal soft X radiographs , with good results ; using a high voltage , it has the same effect as the tungsten target , as a target multipurpose .

Many commonly used electrical switch contact material into a car horn contacts and ignition contacts, voltage regulator contacts , telephone contacts and so on. In operation, the friction between each pair of contacts and spark erosion and high frequency characteristics of the contact , the contact material shall satisfy the following requirements, such as materials, contact resistance, arc volt-ampere characteristics and erosion rates of small and small , tungsten- rhenium alloy contact material is used for the development of new products in recent years , its performance can be used with platinum, rhodium and other noble metal contact material comparable.

In short , tungsten rhenium alloys are widely used in resistor technology , thermal control , modern nuclear technology, astronautics technology, high temperature technology , instrumentation , power vacuum , electrical contact and wear-resistant materials.

High-performance tungsten rhenium alloy completion of the project to achieve a tungsten -3 rhenium tungsten rhenium alloy wire production, but only this one type of tungsten- rhenium wire unable to enter the high-temperature thermocouple industry , in the next phase , rhenium tungsten -3 tungsten- rhenium alloy wire preparation techniques , based on improved equipment and processes through exploration, accumulated successful experience and data , other types of tungsten alloy for late development and lay a solid technology, tungsten, rhenium and tungsten -26 -20 rhenium tungsten rhenium alloy wire production.
