Tungsten Nickel Copper Introduction
Tungsten Nickel Copper 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. The thermal expansion can be adjusted to match
with the following material:
Our Tungsten Nickel Copper Features:
No Fe, Co, Ni, Mn and other elements added as the sintering
activator, to maintain a high thermal conductivity
Excellent hermeticity
Can provide semi-finished or finished (Ni/Au plated) products
Precision machining and excellent dimensional control, surface
finish and flatness
With close technical support including product design, custom
manufacturing, testing and post sale supports.
