99.95% Pure Tungsten Rods Bars,Tungsten Carbide Rods&Tungsten Alloy Rods Product:
Pure tungsten rod specification:
1)Tungsten rods surface finish:
Black:Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.
Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control.
2)Tungsten rods available size:
Forged rods size: Diameter(2-100mm)*Length<2500mm

Tungsten Copper Alloy Property Brief Introduction
W-Cu heat sink material is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape, these features make the application of this composite with great convenience.
1) high melting point, high strength,
2) smooth and clean surface,
3) good conductions, small linear expansion coefficient and good heat-resistance

Our Tungsten Carbide Rods Product Detail Information:
Tungsten carbide rods available types:
1) solid carbide rods
2) single central hole rods
3) double parallel hole rods
4) chamfered rods
5) Customized type rods
Tungsten Carbide rods Application:
Tungsten carbide solid rods are mostly applied for drill bits,end mills, and reamers with sub-micron grain grade YG10X, for non-ferrous precision cutting and wood cutting with grade YG6X, and for fiberglass reinforced plastics, titanium alloys, hardened steel with ultra-fine grain grade YG8X.
Tungsten carbide rod with coolant hole has a wide range of application, such as producing finished cutting tools, such as twist drills, mills, reamers, taps and burrs.
