Product
Description:
It is a composite of tungsten and copper. The coefficient of
thermal expansion (CTE) of the composite can be disigned by
controlling the content of tungsten, matching that of the
materials, such as Ceramics (Al2O3, BeO),Semiconductors (Si),Metals
(Kovar), etc. The products are widely applicated in the fields such
as radio frequency,microwave,high power diode packaging and
optical communication system.
Features:
a.High thermal conductivity;
b.Excellent hermeticity;
c.Excellent size control,surface finish and flatness
Semi-finished or finished (Ni/Au plated) products available;
