Application of Tungsten Rod

Tungsten rods possess special properties, such as low thermal expansion with good thermal conductivity, adequate resistance to electrical resistance, and high elastic modulus. Therefore, tungsten rods are widely used in various fields. Such as support line, lead line, printer needle, various electrodes and quartz furnace, filament, high speed tools, automotive automatic products, sputter target material.

Production Process of Tungsten Rod

Different average forging ratios and forging methods were used to draw the sintered pure tungsten bar, and the annealed tungsten bar was annealed under different annealing systems. The microstructure and physical and mechanical properties of the samples were analyzed by metallographic microscope, hardness tester and density tester. The results showed that:

When the total forging ratio is about 80%, the recrystallization of the tungsten rod forged at one end of one fire is basically completed after annealing at 1300℃ for 30 min, while the recrystallization of the tungsten rod forged at both ends of one fire is completed after annealing at 1350℃ for 60 min when the average forging ratio is larger. After annealing, the hardness of tungsten bars with the two forging processes will decrease, and the hardness of tungsten bars with the former process is less than that with the latter process before annealing and at the early stage of annealing, and this difference is no longer obvious with the completion of recovery recrystallization.
