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.
