Rhenium Tungsten Pin
Rhenium is a chemical element with symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. Rhenium has the third-highest melting point and second-highest boiling point of any element at 5903 K.
Weilai offers straightened and cutted rhenium tungsten wire which is used for wafer testing. Rhenium tungsten pin has high Vicker’s Hardness and Resistivity compared to pure tingsten wire.
By alloying tungsten with rhenium,some of the performance characteristics will be improved such as ductility and processability.This is for example a suitable characteristics where the wire dimension has to be the smallest possible combination with a high strength wire.
Diameter:Diameter of rhenium tungsten pin usually is 0.3mm or 0.5mm.
We can offer other rhenium tungsten pin of different types on demand.
