FAQ


 


Q: what is the size of your tungsten products?


A:For tungsten wire, the diameter is from 0.008mm~3.2mm.


For tungsten rod, the diameter is from 2mm~100mm, length is from 50mm~2000mm.


For tungsten sheet, the thickness is from 0.05mm~2mm,  the width is from 50mm~600mm, the max length is 600mm.


For tungsten plate, the thickness is from 2.1~25mm, the width is from 30mm~600mm, the max length is 600mm.


For tungsten boat, the thickness is from 0.2mm~0.5nn, the width is from 5mm~25mm, the max length is 100mm.


For tungsten tube, the diameter is from 25mm~340mm, the max length is 650mm.


For tungsten crucible,the diameter is from 10mm~500mm, the height is from 10mm~750mm, the thickness is from 2mm~20mm.


 


Q: what is the surface of your tungsten products?


A:For tungsten wire,  we have graphite black surface,  alkali cleaning surface,  electric polished surface.


For tungsten rod,  we have balck surface and polished surface.


For tungsten sheet,  we have alkali cleaning surface and bright surface.


For tungsten plate,  we have polished surface.


For tungsten boat, we have alkali cleaning surface.


Foe tungsten tube, we have machined surface.


For tungsten crucible, we have machined surface.


 


 


Q:What is the thinnest tungsten sheet?


We can achieve the thinnest thickness of 0.025mm, and only a few factories in China can achieve this thickness.


 


Q: what is the properties of tungsten heavy alloy?


A:(1)High density: 17-18.5g/cc;


(2) High hardness and high strength;


(3) High thermal conductivity and low coefficient of thermal expansion;


(4) Good electrical and thermal conductivity;


(5) Excellent machining performance;


(6) Absorption capacity for X-rays and gamma rays;


(7) For W-Ni-Cu tungsten heavy alloy, it is non-magnetic.


 


Q:Can you produce WL20 tungsten electrode as per our physical properties and chemical composition requirements?


A:Regarding WL20 tungsten electrode products, The standard we generally implement is ISO 6848-2004. We can also produce customized products. If you have special requirements for physical properties and chemical composition, please send them to us, our technical staff will evaluate your requirements.


 


How long is the service life of your tungsten crucible?


Usually it is about half a year to a year. In addition, the service life also depends on your use environment and temperature. If the contact temperature is too high, it will affect the service life of the crucible.


We will recommend suitable material & sizes for you according to your requirements.


 


Q:What are the types or grades of tungsten copper alloy?


A:According to different chemical composition content, divide into different product grade levels: For example, if the tungsten content is 70 percent and the copper content is 30 percent, we will call the grade name W70Cu30.  And so on, we have W75Cu25, W80Cu20,W90Cu10 etc.


All types of tungsten copper alloys vary in density, hardness, electrical conductivity, bending strength and other aspect.
