Black Wolfram Wire Dia0.8mm Wolfram Wire for Lighting Applications
Description:
The coarse potassium bubbles in the sintered powder gradually
become long strips after multiple rolling and wire drawing
deformation, and the aspect ratio can reach 20 or more. During the
annealing process, the long potassium bubbles are broken and
segmented into small potassium bubbles.
Tungsten wire is also made by powder metallurgy. By mixing tungsten
powder, the tungsten powder is loaded into a mold and pressed into
a rod in isostatic pressing. The rod blank needs to pay attention
to uniformity, and then it is placed in a high-temperature furnace
for sintering, and the density is improved, but the internal
structure is not dense enough at this time. Then, it is forged to
reduce the diameter, and the density is further improved. At the
same time, the ductility and strength are also improved, which
provides a basis for subsequent drawing. Through wire dies of
various diameters, the diameter is further reduced until the
appropriate diameter is reached. In this process, the tensile
strength of the tungsten wire is also increased.
